Make sure the wire as well as other devices on the circuit are rated for the proper amps for the install. 100-amps is the minimum panel amperage required by the National Electrical Code (NEC), but 150-amps is increasingly common.

How far can a sub panel be from the main panel?

4.5 to 5 feetThe panel must be easily accessible, so don’t install it too far above the floor; 4.5 to 5 feet is about right. The cable you run from the main panel to the subpanel also depends on the amperage rating.

What wire do I need for a 60 amp sub panel?

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.

You can have as many subpanels as you want,provided the combined total demand doesn’t exceed 160 amps.

Can you feed a 100 amp sub panel with a 60 amp breaker?

That 60 Amp should be a 100 amp correct? It is not violate anything for a main breaker to be of less amperage than the max in the box. If it is used for lights, it will probably be okay. … The “100 amp” rating of the subpanel is the max rating that you can feed it at.

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).

What size breaker do I need for a 100 amp subpanel?

60 amp breakerYou can feed a 100 amp panel with a 60 amp breaker, theres no problem there. Running smaller wire will save you quite a bit. Yes you will need 4 wires, and you can use 3#6 thhn and a ground which could be #8.

Can you feed a subpanel from a sub panel?

Yes, it’s redundant, but it’s still required. The wire feeding the new subpanel must be protected from overcurrent by an appropriately-sized breaker. … If using both, 1 must be sized for the conductor, and the other can be that size or larger — convenient if you buy a panel with a 100A breaker preinstalled.
