Welcome. My name is XXXXX XXXXX would be glad to assist.
Are you running residential cables or pipe and THHN wiring?
pvc and thhn.
Then with the THHN, #8 wire is good for the 50 amps you need, a #10 ground wire is all that is required for ground sizing.
Thanks. And for the initial line from the circuit to the fuse box, is #4 good?
What size breaker on the wire?
Is this conduit alos?
1 1/4 conduit for about 60 feet from the circuit to the 125 amp breaker box. The breaker on the jacuzzi wire is to be 50 amps. I will be installing it all.
I hope I answered your question properly.
Not sure, so let me give you the max on all the wiring------------#8 THHN is max at 55 amps, #6 THHN is max at 75 amps, #4 THHN is max at 95 amps (since they do not make a 95 amp breaker, you can up to a 100 amp)
Does that give the answer? Or is it something else?
If you want 125 amps worth, you need #2 THHN wire
I see. Almost exactly. So, is #4 good enough for this from the circuit to the fuse box? It is a 100 amp line with 2 hots and one common (right?). Does each "hot" carry a portion of the total amperage (100 amp/2 = 50 amps)? Once again we are reaching my knowledge limits. I need that 100 amps total, I will be wiring another fuse for my electric car.
You have it correct. The ground wire can be smaller, on 100 amp the ground wire can be #8 THHN
So, run your 3 wires for hots and the neutral, the #8 for ground
So in summary,Circuit to fuse box, #4 for hots and neutrals, #8 for ground will do.
That is correct, they will carry 100 amps
Ok, this was awesome. Thank you very much. I'm totally paying for this service. Thanks very much.Aloha,
