10-3 wire hook up to heat pump?

I'm more familiar with paired, out of phase AB hots to achieve 220V, but when I stepped up to 10 gauge needs, the only wire I found was 10-3, whats the proper procedure? I'm hooking up a heat pump with 2 blacks and a green, and it requires local bonding to ground via a lug on the outside of the unit. I assume it's black->black red->black white->green but what about the bare ground in the 10-3? It doesn't go to the external lug, so how is it handled in this scenario?

Thanks

You could have used 10/2. Since you don't need the white wire, just cap it at both ends witha wire nut.

Florescent Light Hum

I have a florescent light that is silent when first turned on. Then, perhaps after a half-hour it starts to hum. I suspect it is a heat related problem but I am not sure. What should I look at to track down the source of the problem? Thanks.Read More

Dead Circuit

Randy Smith on Apr 17, 2004

I have a 30 year old house with alum wiring. One entire circuit suddenly went dead. Nothing had changed, just went dead. The breaker was not tripped. Checked the breaker by switching wires and it is ok. There are no GFIs on the circuit. Circuit is 20 amps with 6 plugs, 2 lighting fixtures and one ceiling fan. Where do I look from here?Read More
