Smart homes are not just about apps, cameras, and voice assistants.
The real work happens behind the wall.

Before adding smart lighting, thermostats, cameras, EV chargers, access points, or backup power, the wiring plan has to make sense.

That means checking the panel, planning cable runs, thinking about Cat6 or Cat6A, leaving room for future upgrades, and making sure outdoor devices are wired the right way.

Because a smart home is only as smart as the wiring behind it.

Stop wasting time digging through product pages for specs, sizes, and product details.

Nassau product pages include a spreadsheet that keeps the information organized in one place, helping buyers, contractors, and estimators review what they need faster.

Less searching. More clarity. Smarter ordering.

Check the spreadsheet before you order.

10/2 and 10/3 may be the same gauge, but they are not the same setup.

10/2 has two insulated conductors and a ground. 10/3 has three insulated conductors and a ground.

Before you order, check the voltage, amperage, and whether the circuit requires a neutral.

The wrong wire can mean reorders, delays, and wasted money.

Order the right wire the first time. Shop Nassau National Cable.

Some electrical work is better tested before it goes live. ⚡😅​

When the job can’t afford surprises, make sure you’ve got the right wire, the right specs, and a supplier that knows the difference.

This happens more often than people think.

If nobody can confidently identify the cable, stop and verify it first.

A few minutes of checking can save hours of problems later.

Need wire for a 50 amp breaker?

For runs of 100 feet or less, Nassau’s guide points to 6 AWG copper or 4 AWG aluminum as the usual recommendation. If the run is longer, you need to account for voltage drop, which can change the wire size.

That is why ordering by memory is how mistakes happen.

Check the breaker size, wire material, run length, and application before you buy.

Your backup supplier should not be found during the emergency.

On large data center and mission-critical projects, cable is part of the construction schedule. If the primary supplier cannot deliver, or the scope changes mid-project, the backup plan should already be in place.

Nassau can support high-volume data center cable projects as a primary or backup supplier.

Have you ever had a supplier delay mess with a project timeline?

**Measure before you order.**

Sounds obvious, but this mistake happens more than it should.

A wrong length does not just mean the cable is off. It can slow the job down, force a second order, and waste time you did not need to lose.

And of course, we are always here to help with reshipments, exchanges, and anything else you may need.

UF-B and NM-B look similar.

That is where the similarities end.

One is commonly used for indoor residential wiring in dry locations. The other is designed for outdoor, wet-location, and direct burial applications.

Choosing the wrong cable can lead to failed inspections, rework, delays, and unnecessary costs.

Before you order, make sure the cable matches the environment where it will be installed.

Right cable. Right job. No headaches.
