Baby its Cold Outside!

Here in the South, we face alligators, snapping turtles, mosquito swarms, and 110-degree heat without a whimper. However, when the weather turns cold and the forecast is for icy rain, we become helpless!

With it expected to be 29 degrees in Baton Rouge on Sunday night, and even colder thru most of the Southeast, it seems prudent to offer some cold weather survival skills. While the folks in the Northeast and the Northern Plains States may laugh, this weather presents a serious survival challenge to us. Here are a few tips to help you get thru this safely:

First remember your Hurricane preparations (except instead of a raincoat you are going to need a heavy jacket!!):

• Stock up on food and bottled water, medicines, and if needed, infant supplies like diapers and formula. For me, necessities include Diet Mountain Dew and Reece’s Cups! Even if the stores are open, you don’t know how to drive in icy conditions and should stay home until the weather clears. Freezing to death in a ditch is not a pleasant way to go.
• Get the portable generator out of storage and make sure it will start. Store extra gasoline safely.
• Fill the bathtub(s) with water. If utility water service is lost, this water can be used to wash and flush toilets.
• Fuel your cars/trucks now, don’t wait until Sunday afternoon when the lines are long and the supplies short. But didn’t you say to not drive? Yes, and I meant it, but the vehicle can serve as a short-term emergency warm shelter and as a way to charge phone batteries.
o Have the radiator system serviced or check the antifreeze level yourself with an antifreeze tester. Add antifreeze as needed.
o Replace windshield-wiper fluid with a wintertime mixture.
• Now lets get the house ready –
o Seal off unused rooms by stuffing rolled-up towels in the cracks under the doors. At night, cover windows with extra blankets or sheets.
o Have a plan to take care of your pets. They need adequate shelter. In sub-zero temperatures, their paws, noses and ears can succumb to frostbite—bring them inside. If you can’t bring them in your home, house them in a garage or basement with plenty of warm bedding.
o Keep your pipes from freezing. Wrap them in insulation or layers of newspapers, covering the newspapers with plastic to keep out moisture. Allow a trickle of water to run from a faucet if your pipes have frozen in the past. This will keep the water moving so that it cannot freeze.
o Know how to shut off your water if a pipe should burst.
o DO NOT USE YOUR CHARCOAL GRILL IN THE HOUSE – Carbon Monoxide is deadly!!!
• Check in with elderly or disabled relatives and neighbors to ensure they are safe. Again, get them situated BEFORE the freeze comes – stay off the road!
• But I used to live up North, I know how to drive in ice and snow! Well, even if that is true, you will be on the road with hundreds of other who don’t. Did I mention – STAY OFF THE ROAD! AGAIN - FREEZING TO DEATH IN A DITCH IS NOT A PLEASANT WAY TO GO.

WHY WOULD A PERMANENTLY INSTALLED EMERGENCY GENERATOR NEED A CAM-LOK CONNECTION PANEL?
Having a well-designed set of pre-installed cam connectors, in a convenient area, will allow for quick, safe, and economical load bank testing of generators on a scheduled basis. They eliminate the need to disconnect permanent wiring and will reduce the time, and costs required to service the generator.
There are many factors to consider when installing a permanent emergency generator system. Call today and allow us to help you design a safe and easy-to-maintain installation.
Emergency Generators must be periodically tested under load to ensure they will start, run, and provide power when needed. Many emergency generators are sized for reduced loading, providing power to only a limited number of priority circuits. Tripping the main power source to test the emergency generator would leave much of the facility without power.
Therefore, the generator is tested by connecting to a portable, temporary load bank, basically just a large resistor that substitutes for the load the generator would see in an emergency. Connecting and disconnecting the load bank can be a labor-intensive operation, and puts the facility at risk if a power outage occurs during the testing.

J Custom Supply, Inc.
2025 Hurricane Preparedness Checklist

At J Custom we have been designing and supplying portable and emergency power systems for over 45 years. While most of our customers are commercial and industrial facilities that need reliable power systems during emergencies, we feel a sense of responsibility to our friends and neighbors to share some important information about what it takes to survive a hurricane. This is expected to be a hot summer and a very active Hurricane season. Please take this advice seriously as the lives of your loved ones may depend on it.
But wait! There is nothing active in the Gulf right now, so why worry about it until a storm actually comes? Because if you wait, the home supply stores, grocery stores, gas stations, and other venues are typically crowded and chaotic, and often sold out when hurricane watches and warnings are issued.
The most important thing you can do as hurricane season approaches is to get yourself, your family, and your home prepared NOW. Don’t wait until everyone is rushing to “get ready.”
You should prepare for two separate responses to an approaching storm: one is to have the necessities to stay in your home and ride out the storm, and the second is to be prepared to evacuate to a safer location and stay away until the storm passes.
The decision to stay or go obviously depends on the expected storm track and your comfort level. If you live in a low-lying or coastal area that is expected to be in the direct storm path, please leave! Expect the roads to be crowded and plan accordingly.
For Evacuation
Pack the items you would most likely need during an evacuation in an easy-to-carry container, preferably one that is waterproof. If nothing else, use some large plastic garbage bags to pack. Unless you have an open bed pick-up or a rear luggage carrier, it is not recommended to carry spare gasoline in your vehicle, however, you should fuel your vehicle as soon as a Hurricane Watch is declared in your area and never let the fuel level go down past half full.
You should pack some cash, credit cards, insurance cards, some non-perishable food items, some bottled water, and any prescription medications. If you have important papers in your house, such as wills, deeds, and vehicle titles, pack them in large zip-lock bags to prevent them from getting wet. Look at the size and capacity of your vehicle and be reasonable in what you will take. Yes, the things in your house are precious to you, but they can be replaced. Your first goal must be the safety of your family! If you will be evacuating with pets, you need their food and leashes for dogs or cages for cats. Call hotels in a safe/host location and ask if you can bring your pets. Ask the manager if a no-pet policy can be lifted during the disaster. Most emergency shelters do not admit pets.
If you have infants, you will need formula and diapers. Remember you may be on the road for many hours just to travel a short distance. It is a good idea to take a roll of toilet paper as many of the roadside facilities will see heavy usage and may be out.
Riding out the Storm at Home
If you plan to stay you should prepare for the loss of basic utilities. Your home should be stocked with six basics: water, food, first aid supplies, clothing and bedding, tools and emergency supplies, and special items.
Emergency Generator: This will be the subject of a separate article, as there is a lot to consider. The following assumes that you either do not have a home generator or are unable to obtain fuel. It is geared toward riding out the first few days without power or assistance.
Water: Buy several cases of water in plastic containers. Use all the extra freeze space to freeze as many water bottles. This will keep your food cold a little longer when the power is lost, and then still be available to drink. A normal person needs to drink at least two quarts of water each day. Hot environments and intense physical activity can double that amount. Children, nursing mothers, and ill people will need more. Have at least a three-day supply of drinking water for each person in your household as even if the water supply is not lost, it may be contaminated. Fill all bathtubs and sinks in your home with water, this can be used for food preparation, bathing, and toilet flushing if you lose water pressure.
Food: Store at least a three-day supply of non-perishable food. Select foods that require no refrigeration, preparation or cooking, and little or no water. Many homes have gas cooktops in the kitchen, which normally work without electricity if you light them with a match, however, natural gas was the first service lost in New Orleans during Katrina! If you must heat food, pack a can of Sterno, DO NOT USE A CHARCOAL GRILL INDOORS!!! Some suggested food items are ready-to-eat canned meats, fruits, and vegetables (remember to have a non-electric can opener!) and canned juices.
First Aid Supplies
Assemble or purchase a first aid kit for your home and one for each car. Include non-prescription drugs like aspirin or nonaspirin pain relievers, anti-diarrhea medication, antacid (for stomach upset), a laxative and some activated charcoal (for poison treatment.)
Most normal households will have most of these items, just check and be sure that you do!
Tools and Supplies
Paper cups, plates, and plastic utensils
Zip-lock bags to store food when opened
Battery-operated radio and extra batteries
Flashlight and extra batteries
Cash and/or change
Non-electric can opener, utility knife
Fire extinguisher: small canister ABC type

With the busy part of Hurricane Season coming on, it is time to repost this about Snake Bite Cables:


There is a reason we call them “Snake-bite” cables!!
Here in the Southeast, along with plenty of sunshine and high temperatures, we also get to enjoy Hurricane Season. There are many things that you need to do if a hurricane warning is issued and most of these things will be covered by your local, state, or federal Emergency Management agencies. However, there is one item that you may want that everyone (including me) is reluctant to even mention. A lot of people assemble a cable with male plugs on each end to be able to hook a portable generator into their home’s electrical system without a proper transfer switch. Understand that we DO NOT SELL THESE CABLES AND WE DO NOT CONDONE THEIR USE. We call them “snake-bite” cables because they can cause tremendous damage and even kill. If you want to be able to run your entire house on backup power, please have a proper transfer switch installed by a licensed electrician BEFORE the hurricane puts you in the dark. If you are in an emergency, where you need to run lights, fans, and your refrigerator on a portable generator, please use proper-sized extension cords and do not connect to your home’s electrical system.
Having said this, I know that many people will not heed this advice and either have, or will soon assemble, a snake-bite cord. So we hope to help you at least try not to kill anyone or burn your house down. A snake-bite cord is an electrical cable with male plugs on both ends. It can be plugged into the generator and also into an outlet in the house so that the generator is connected to the house electrical system. Usually the house plug is a larger 240 volt unit and plugged into a dryer outlet, thus providing power to all of the electrical systems in the house. If you do not know how to wire up this type of cable, please don’t call us – we won’t help you!
Assuming that you have obtained a snake-bite cable, and plan to use it, again against our advice, at least follow these instructions to try and keep from killing someone:

1. DO NOT START THE GENERATOR UNTIL STEP NUMBER SIX (6). If that snake-bite cable is powered up by the utility company or your generator, before you connect both ends, the male pins that are exposed are hot and they will kill you if you touch them. (Starting to see why this is NOT something we recommend?)
2. Turn off the main breaker to disconnect the house wiring from the utility line. This is MANDATORY, otherwise, when you start the generator you will feed electricity back into the grid and possibly injure or kill anyone working on the grid. You will be responsible for this injury or death and will suffer serious legal consequences.
3. Turn all of the breakers in your electrical box off. Yes, EVERY SINGLE ONE.
4. Plug the snake-bite cable into the house outlet you are going to use.
5. Plug the snake-bite cable into the generator.
6. Following the instructions that came with the unit, start the generator and power up the snake-bite cable.
7. Turn on the individual breakers for the circuits you are going to use. Remember that both the power available from the generator, and the available gasoline supply during a storm, will both be very limited. Choose wisely – central air conditioners, electric clothes dryers, and high-wattage hair dryers are not items you want to run off of even a larger portable generator.
8. If you stop the generator for any reason (refuel, check oil, etc) turn off all individual breakers before restarting, then add the load back slowly. Do not restart the generator under a full load.
Once the Storm has passed and utility power has been restored:
1. Stop the generator.
2. Check the Main breaker to ensure it is still OFF – remember, if that snake-bite cable is powered up by the utility company or your generator when you disconnect it, the male pins are exposed and will kill you if you touch them. (We told you this was a bad idea!)
3. Disconnect the snake-bite cable at both ends.
4. Turn all the individual breakers off.
5. Turn the Main breaker back on.
6. Slowly turn the individual breakers back on.
7. Properly stow the generator. We covered this in an earlier newsletter.
8. Offer a prayer of thanks for surviving both the storm and your use of a snake-bite cable!
Wait – how did I know the utility power was back on?
Good question, since you CANNOT be connected to the utility line while running your generator. So check your neighbors who don’t have a generator, look at any local street lights or call the utility company – just don’t tell them you were using a snake-bite!

Memorial Day weekend has come and gone. It is the middle of June and the the days have gotten long and HOT! The Gulf waters are hot as well and we are expecting an above average hurricane season.

So now is the time to get out your emergency generators and see if they will start. If you followed our posts about how to store them for the winter, a fresh tank of fuel and a battery charge will be all you need. If not, the carb is probably gummed up, the oil needs changing and the thing will be useless in an emergency.

Get it fixed and running NOW before the rush starts. If you don't have one, you should start shopping now, please don't wait until the day AFTER the hurricane hits!

I am running late on posting our 2024 Hurricane Preparedness Guide, however it will be complete and on our website by the end of next week.

08/15/2023

The DS-240 Double Set Screw splice kits are designed for repair of damaged or cut cables or for extending the length of a cable in the field. They fit 2/0 to 4/0 MCM wire. These splice connectors have been designed to operate safely at 400 Amps at 600 Volts, AC or DC.
Different size cables may be joined by using the DS-240 splice kit. This feature is useful where existing cable must be extended or long sections need to be replaced. A section of larger cable can be added to provide adequate protection from voltage drop or used to reduce the cable inventory carried for repairs.
The splices can be assembled with simple hand tools and hydraulic crimping equipment is not needed. Our insulation retention feature prevents the insulation from slipping down the conductor when under strain and the pull-out strength exceeds the breaking strength of the cable. Mil-Spec Heat Shrink Insulation is rated for direct burial service.
