Is the new one 240 also?
Your wall outlet is 4 prong and the cord from the oven is 3 prong? This is a new oven?
The wall is four prong, the new one (It's a cook and hold) didn't come with a cord, but they only require 3 wires and has no spot for a neutral. Yes it's new.
You would use the two hots and the ground. If the oven was using 240 and 120 you would need the neutral wire.
Can I put the neutral together with the ground or do I just leave it hanging there? ETAAnother question is a 10ft cable safe to use? It seems UL don't certify them
What size wire is the cable and how many amps does the oven draw?
I did not buy the cable yet. It's under 30A
ETA: I see what you mean. 10ft not UL certified
Yup. Also I would need a 4 prong one like thishttps://www.amazon.com/dp/B0014KO11O/
The white wire just cut and tape or just tape.
There are two wires over one of my outside doors that were probably a security light at one point. When I test them one is hot the other is not. When I flip a switch in the garage both of them turn hot. Does that make sense?
Is there more then one switch? Does another switch make them both not be hot?It's possible when you turn the switch on its a completing a circuit somewhere (perhaps turning on a light?) and and therefore the neutral would be live.
You are measuring to ground or metal conduit? What do you get going across the two wires with switch on/off?
I'm measuring with a voltage testing pen. I haven't tried crossing them and probably don't feel comfortable doing so.
No self-respecting DIYer would use one of them. Don't cross them. I am talking about going across them with a meter. One lead of meter to hot and other lead of meter to neutral.
I beg to differ, while not very accurate it's by far the easiest and has it's use cases.
But it could read induced voltage which will make it seem you have a hot wire when you don't. Maybe the new ones are better.With meters so cheap I would never use a pen.
