Choices for wiring aluminum to copper for oven
Following up on my earlier post about needing to connect No. 6 aluminum
in the wall to (amazingly thin) No. 16 copper for the new oven ... I haven't found any connector made for No. 6 aluminum and No. 16 copper. A split bolt I've seen is for 6 through 10, and a Polaris connector I've seen is for 4 through 14. Two appliance installers have told me they'd just use a wire nut (one guy specifies a gray or maybe blue one). An inspector and some electric supply guys think a wire nut is a bad idea. I don't much like the idea of using a split bolt rated for a larger wire. One installer says they're kind of a mess and require two kinds of tape. The Frigidaire oven manual says the insulation on the wire is rated for higher temperatures than ordinary household wire insulation. The manual, for more than one model, says the oven draws "up to" 4000 watts, but a plate on the oven says 3.4 kilowatts at 240 volts. So that's either a max of 16.7 amps or 14.2 amps. The old double oven had gray wire nuts. What would you do? |
