What size wire do I need to run a 100 amp sub panel?
Also, what size wire do I need to run a 100 amp subpanel?
A 100 A sub-panel requires a two-pole 100 A breaker - if you want 100 A. You can use #4 AWG 75 deg C or 90 Deg C copper wire in conduit for a 100 A breaker provided the breaker is labeled for use with 75 deg C wire.
Similarly, can you run a 100 amp sub panel off a 100 amp main panel? To the best of my understanding, there is no code issue running a 100A subpanel off a 100A main panel, so long as the wire size is correct, and the installation is correct. For a subpanel, you need four wire service (two hots, a neutral, and an equipment ground).
Likewise, people ask, how many amps can a 100 amp panel handle?
What size wire do I need to run a 60 amp subpanel?
In practice, however, it's common to wire 60-amp breakers with 6-gauge, 3-conductor wire because an appliance that needs a 60-amp breaker seldom draws the full 60 amps. If you're installing a 60-amp subpanel, however, it's best to connect it to the main panel with 4-gauge wire.
