What size of wire is needed for a 100-amp service?
What size of wire is needed for a 100-amp service?
The cable must have a wire gauge sufficient to the amperage of the subpanel—a 100-amp subpanel requires #4 copper wires or, more commonly, #2 aluminum wires, for example. (Aluminum is often used for feeder cables because the cost is typically much lower than that of copper wires.)
What wire do I use for a 100-amp sub panel?
When installing a 100-amp sub-panel, you will need to use either 4AWG (American Wire Gauge) copper cable or 2 AWG aluminum, three-conductor cable. Aluminum cable is cheaper than copper cable and carries the risk of corrosion. Three-conductor cable comprises four wires — two hot wires, a ground wire, and a neutral.
What wire size do I need to go 100 feet for a 100-amp service to a workshop?
For a 100 ampere circuit, the conductors will likely be required to be 3 AWG copper or 1 AWG aluminum.
What type of wire is used for overhead service?
SE-U (Service Entrance – Style U) Cable SE-U is most commonly used for service entrance applications, to connect the meter socket to the main breaker panel. It is also commonly used for overhead service drop applications, to connect the overhead service cable to the meter socket.
What is the minimum size overhead mast for a 100 amp service?
1½-inch rigid steel conduit mast is required for a 100 to 150-amp entrance, when the service wire attachment point is on the conduit.
How big of a wire do I need for 100 amp?
The rule of thumb for 100 amp is that you go with a wire size gauge 1. 125 amp requires a wire size 2/0. For 150 amp, the right wire size is 3/0. For 200 amp, you will want a wire size 250 kcmil. For 300 amp, the right wire size is 500 kcmil. 400 amp service requires a wire size of 1,000 kcmil.

What’s the correct wire size for a 100 amp riser?
Electrician: Mike G. The proper wire size is 2 #2 and 1 #4 Aluminum. If you’re using a cable for the riser then that would be a 100A SEU.

How big of wire do I need for a 100A breaker?
A 100A breaker would require a #8 cu or a #6 al. If you are calculating full load then the grounding conductor must take voltage drop into account and rise a full two sizes more just like the current carrying conductors or a #4 cu or #2 al. So once again take some time and think about what you need.
