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

You can use the 100 amp panel off a 60 amp breaker if you determine that it is adequate, but I would suggest that in sizing your feeder wires and conduit it would be a good idea to size them to accomodate 100 amps.

Your feeder wires are where most of the work for this project will be..

## How far can you run a 12 gauge wire?

The following are the maximum lengths of cable you can use while still maintaining a 3 percent voltage drop for the given wire size (AWG) and circuit voltage….For 120-volt circuits:14 AWG50 feet12 AWG60 feet10 AWG64 feet8 AWG76 feet6 AWG94 feetOct 20, 2019

## What gauge wire do I need for a 50 amp breaker?

6For a maximum of 50 amps, you’ll need a wire gauge of 6. Fifty amp breakers are most often used to power many different appliances.

## What size wire should I run to my shop?

The minimum size wire you can use is #4-4-4-8 copper or #2-2-2-6 aluminum based on table 310.15(b)(6). Either of these provides about 5% voltage drop at maximum load. Code does not require you to upsize wires for voltage drop, but you might want to get to 3% which is the standard design goal.

## Can I put a 50 amp breaker in a 100 amp panel?

There is no problem using a sub panel that can take more current than you will ever feed it. Points to note: The cable to your hot tub will be rated for 50A (not 100A); therefore you must not upgrade the breaker in your main panel to 100A.

## Can you use a 100 amp breaker for a 125 amp sub panel?

A 125 amp rated panel with a 100 amp OCPD as the main and a sub with a 20 or more breakers.

## How many circuits can you put in a 100 amp panel?

20 circuitsIt can hold 16 full size breakers and 4 twins breakers for a total of 24 circuits. Many 100 amp panels are simply 20 circuits.

## Does a sub panel need a main breaker?

Subpanel main breaker A main breaker on a sub-panel is not necessary because this is in the same building (if you are in a different building then NEC 225.31, 225.32, 225.33 apply). That said, having a main breaker in the sub-panel is also acceptable.

## Can you run a 100 amp sub panel off a 100 amp main panel?

You can run a 100 amp subpanel off a 100 amp main panel because the total can be up to twice the amperage of the box, meaning you could run a subpanel of up to 200 amps. What’s critical, though, is that the subpanel is safely and correctly connected to the main panel and that you don’t overload the service panel.

## Can I put a 60 amp breaker in a 100 amp panel?

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.

## What size breaker do I need for a sub panel?

Subpanel Circuit Breaker Sizing and you can simply round up to the next higher size of the breaker. For example, if the load calculation comes out to 48 amps, you should use a 50-amp breaker to protect the circuit. Feeder circuits supplying subpanels are 240-volt and require a double-pole circuit breaker.

## What size wire is needed for a 100 amp sub panel?

This is typically a three-wire cable with three insulated conductors plus a bare copper ground wire. The cable must have a wire gauge sufficient to the amperage of the subpanel—a 100-amp subpanel requires #4 copper wires, for example.

## How much can a 100 amp service handle?

100-amp service is generally large enough to power a small- to moderate-sized home’s general branch circuits, plus one or two electric appliances, such as a range, water heater, or clothes dryer. This service may be sufficient for a home under 2,500 square feet if the heating appliances run on gas.

## What wire size do I need to go 100 feet for a 60 amp service to a workshop?

If this were my shop, and I needed 60a service at 100 feet, I would likely run 8 gauge wire, 8–3w/ground. this gives you the opportunity to run two 120v circuits off two different breakers from your main panel to the shop.
