how to wire 100amp box off of another?

Question

I am wiring my garage with 100 amp box, how do I run wires from home box to garage box 10-2 wire orhow ,thank you

Answer 1

The best thing in the other 2 answers are you should get an electrician. Another good point is you don't say if the garage is attached or not. If detached, there are many more rules for another building. You should run 10-3 with ground for a 30A feeder, and if an attached garage, forget about ground rods. The neutral and grounds must remain separated in the subpanel. I doubt you really need 100A in your garage, especially if you have 100A service, since the house needs part of that. The size of wire for larger feeders depends on the type of wire. The other answer of 4AWG for 100A only applies to the service to a house, it would need to be bigger for the garage, and bigger if you need romex or UF. But they don't make bigger, so your only choices are SER cable or a conduit method. There really is so much to know you should get an electrician.

Answer 2

A 100 Amp Load Center can have from 6 to 20 spaces for circuit breakers.
The normal size feed is #4 AWG copper wire.
The bare minimum with your #10/2 (ground?) will allow you 2-15 Amp circuits (lighting only).
If you were to use 10/3 Wground, you could have 4 -15 Amp breakers, or 1 -15 Amp lighting circuit and 2 -20 Amp receptacles.
I would use 8/3 w/ground (at least) unless you are going to use some heavy equipment.
You didn't say whether you were staying indoors with this wiring or going outside.
Type UF is for direct burial or buried in conduit. This of course is a different set of rules. Hope this helps. Good luck! !
With your 10/2, You should use a 30 Amp breaker in the box you are coming from.

Answer 4

no no.
you have to have a neutral and ground
you can put a ground rod next to the garage box to run your ground but you have to have 3 equal sized wires
from the main box to the sub panel.
also they have to be way bigger than 10gauge.
I don't have my code book handy but I'm thinking
#2 for 100amp service.
you would run the wires from the main panel on a
NEW 100amp breaker to the new sub panel which
would also have a 100 amp main disconnect breaker.
the neutral wire would go from the neutral busbar on the main panel to the neutral busbar on the sub panel.
Since you do not appear to be experienced with this,
I highly reccomend you get an electrician.
