[440volt]

I'm remodeling the kitchen and putting in new appliances . Im putting a 220 line in for a double oven where the refrigerator once was. The outlet where the oven is going is a 4 x 4 box with 1/2" EMT from the breaker box. Two questions:

1. Will 1/2 " EMT accomidate two 8 gauge hot wires and two 10 gauge wires for ground and nuetral.

2. With about a twenty foot run from the breaker box to the appliance direct connect box, can I use smaller than 8 or 10 gauge wire for the ground and nuetral?

Thanks in advance.

I did the wire fill calculation for you, for 2 - #8 and 2- #10 THHN wire, in 1/2" EMT. Conduit will allow .122 sq in at 40% fill of wire, and the wire adds up to .1154 sq in of volume.

These wires will just fit in that conduit, just barely legal.

No electrician would do this. If at all possible, change out the conduit to 3/4", but I suspect the reason your asking is to change the conduit would be difficult.

You may want to use wire lube, be sure it is rated for wire pulling. DO NOT USE soap, oil, etc.

Yes, the neutral can be #10 THHN copper.
