Can you run a sub panel off of a sub panel?
You can connect a sub panel to a sub panel, if the allowable capacities are observed(# devices, wire current capacities) and you keep neutral and ground separate all the way through both sub panels.
What size ground wire do I need for a 100-amp subpanel?
You are correct that for a 100A feeder, the associated ground wire needs to be an 8AWG copper or 6AWG aluminum wire.
What size wire do I need for 125 amp sub panel?
If you’re a homeowner and need 100A delivered to a 125 subpanel within 100 feet at 75 degree C, for example, then you’ll need, according to universal recommendations, a #1 copper or a #1/0 aluminum wire.
What size wire is needed for a 50 amp sub panel?
In most cases, 6 AWG is an almost perfectly-sized wire for a 50 amp breaker. In limited cases, you will probably have to use a larger 4 AWG wire. That’s when you have a long circuit and are sending electrical current at some distance (100 feet or more).
What size ground wire is needed for a 60 amp sub panel?
For 60 ampere breakers, electricians and professionals suggest using a wire size gauge ranging from 6 AWG to 4 AWG. All household wires have a rating of at least 600V, so only amperage really matters when it comes to determining wire gauge.
What size wire do I need to run a 200 amp sub panel?
The ground wire in the feeder needs to be a minimum of 8AWG copper and a grounding electrode (ground rod) will need to be driven at the shop and connected to the shop subpanel by an 8AWG copper wire.
Can you feed a 100 amp sub panel with a 60 amp breaker?
You can feed a 100 Amp panel with a 60 Amp breaker. Keep in mind that the sub panel needs to be rated above the breaker size.
Can a 100 amp main panel feed a 100 amp sub panel?
First the panels you are looking at that are rated 100A simply means you can use them for any application up to 100A. You can for example add a 60A breaker to your existing panel and protect the new subpanel with a 100A rating.
Do I need a ground rod for a sub panel?
Yes, any sub panel outside of the main building requires it’s own ground rod and a ground wire back to the main building. And yes, a sub panel in the same building as the main does not need a ground rod – only the ground wire.
