Can you use 6 gauge wire for 100 amp service?
You can feed as many 100A subpanels as you want with #6 wire, as long as the wire is supplied from 60A breakers. Breakers protect wires.
How far can you run #2 aluminum wire?
Example calcuation 2 – Aluminum Wire, 3 Phase power Cable run: 400 ft. 1 conductor per phase utilizing a 750 kcmil Aluminum conductor installed Direct Buried will limit the voltage drop to 2.64% or less when supplying 194 amps for 400.0 feet on a 240 volt 3 phase system.
What is #2 copper wire?
#2 Insulated Wire #2 grade insulated copper consists of unalloyed wire – thinner than 16 gauge – which includes heavy, double or plastic insulation. The grade generally covers many common types of telecommunications wiring as well as electronics such as outlet and extension cords.
How many watts can a 125 amp panel handle?
Another way to determine the max electrical draw for your house is to find the max amperage of your circuit panel which may say 125A. In that case, your house’s max draw at any given time would be 125A x 120V = 15000 watts.
Can you run a 100 amp sub panel off a 100 amp main panel?
First the panels you are looking at that are rated 100A simply means you can use them for any application up to 100A. You can for example add a 60A breaker to your existing panel and protect the new subpanel with a 100A rating.
What size wire do I need to run 50 amps 150 feet?
