Oven Electrical Question
I am replacing my built in oven/microwave combo with a separate thermal oven
and a microwave. The oven will take 220 V, the Microwave is a plug-in (built-in) above the oven and requires 110V. Can I extract 110 V for the MW from the 220 V junction box (line to 220V thermal oven )? The 220 V line has a 40 Amp Circuit- breaker. This house is 25 years old. I cannot tell if 3 or 4 wires go from the main panel to the junction box. -- Walter www.rationality.net - -- Posted via a free Usenet account from http://www.teranews.com |

No, you'll need to run a dedicated circuit for the microwave

25 years old is probably 3 wire. That makes the idea impossible, even if
you were willing to put in a load center. It would be a bad idea in any event. "Walter R." wrote in message ...

I cannot tell if 3 or 4 wires go from the main panel to the junction box. ... but you need to find that out first. With 3 wires, it's impossible to do it safely and legally (you need, but don't have, a neutral). With 4 wires, it's merely impractical. Here's the problem you run into with four wires: the microwave almost certainly is intended to plug into a 15A (or maybe 20A) 120V circuit, but your existing wiring is likely 8-gauge. 120V receptacles aren't rated for wires that large, and cannot grip them securely, so you'll have to have 12- or 14-gauge wires going to the receptacle for the microwave -- but it's a Code violation to put anything smaller than 8-ga on the 40A circuit that you now have. -- Regards, Doug Miller (alphageek at milmac dot com) It's time to throw all their damned tea in the harbor again. |
