#2 romex would only be good for 95 amps. If protected with a 100 amp breaker be prepared to show load calcs that load is 95 amps or less.

Do I really need to wait 4 hours between coats of paint?

The cable must have a wire gauge sufficient to the amperage of the subpanel—a 100-amp subpanel requires #4 copper wires, for example.

Thereof, 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.

Also to know is, How many amps can 2 gauge wire handle at 12 volts? Amps @ 13.8 Volts LENGTH OF WIRE American Wire Gauge (AWG)
—————– —————————————-
125-150 8-ga.
150-200 6 or 4-ga.
200-250 4-ga.
250-300 4-ga.

Subsequently, question is, How many circuits can you have on a 100 amp service? Other electricians suggest another simple rule-of-thumb: 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.

Also, Can you put a 50 amp breaker in a 100 amp panel?

Yes, that means you may have a 150A breaker in the subpanel being fed by a 50A breaker. That is fine.

How many amps can 2 0 gauge wire handle?

Can I put a 50 amp breaker in a 50 amp sub panel?

It’s not only possible, but reasonable. The 50-amp breaker in the main panel is sized to protect the conductors from the main panel to the sub panel. A 50-amp breaker in the sub panel might be sized as such because of a high in-rush or start-up current requirement (as might occur in A/C and refrigeration equipment).

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

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.

What size wire do I need for a 100 amp sub panel?

You need a 3-3-3-5 copper SER cable to carry 100 amps (that’s three #3 gauge for the two hot wires and the neutral and a #5 gauge for the ground).

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

If the main panel is breakered at 100A, and the cable supports 100A, and the subpanel supports 100A, then the main main breaker protects them all. You don’t need any breakers for the sub. You can use thru-lugs or snap-in lugs in the main panel.

What is #2 wire rated for?

Copper
– ——
4 70
3 85
2 95

How many circuits can be on a 100 amp panel?

20 circuits

What size wire is needed for a 50 amp sub panel?

Check what size cable you will need for the amperage chosen and the length. For example, 6-3G cable is designed for 50 amps when the length of wire does not exceed 55 feet. Beyond that length, a thicker wire is required, due to the voltage drop.

How many breakers can I add to my panel?

Actually the limit is 42 regardless of panel size, although a 32 space is the largest 100 available, but not readily. Most 100s are 20 space or 20/24. As far as twins (or skinnys, or half size) breakers this has ONLY to do with what the panel will accept.

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

4-gauge wire

How many amps is #2 Thhn good for?

Conductor Size (AWG/KCMIL) 60°C/140°F TW, UF 90°C/194°F TBS, SA, SIS, FEP, FEPB, MI, RHH, RHW-2, THHN, THHW, THW-2, THWN-2, XHH, XHHW, XHHW-2, USE-2, ZW

2 95 130
1 110 145
1/0 125 170
2/0 145 195

Can you put a 50 amp breaker in a 60 amp panel?

Yes but the over current protective device (breaker) feeding the panel can not be more than 70 amps.
