Background is we are selling our house and moving out of state. I've been fixing big and little things and painting for several months now, as well as purging possessions and packing.
House was built in 1961/1962 and has mostly old two conductor cable supplying everything.
I might add that the previous owner who I think did this work or most of it, IS a licensed electrician in this state! And this is not the first thing I've seen done poorly or incorrectly in this house.
When we bought the house, every outlet was a 3-prong outlet, most with no ground. I found some that have a wire connected between ground and neutral, which I can only guess was done to fool the home inspector when we bought the house. There has been some newer work in the kitchen, bathroom and garage that I verified has a proper "Earth" ground by checking continuity to the copper water pipe being used for ground in the garage, and to the grounding rod in front of the house.
We pulled out the kitchen range to clean behind and I was going to check out the power outlet to make sure it was connected correctly and has a proper ground (gas fired range and needs 15A/120V power for controls, fans, lights). But I found that the range is not plugged into an outlet. Some previous owner ran an extension cord through holes in the cabinet and plugged the range into that. I don't know where the extension cord is plugged in--I suspect the same outlet as the fridge, but we haven't pulled the fridge out yet.
So I know I need to install at least a 15A receptacle for the range, per the install instructions for the range.
There is an over range microwave that has power consumption of 1650W per its user manual. It is plugged into an outlet that has opened another can of worms. Whoever put that in ran power to it via 14/2 Romex from a junction box below it that is original work for this house, and maybe used to have an outlet or a light switch.
Closeup photos of the junction box and outlet for microwave:
Here's a diagram I drew of the layout because I can't get back far enough in small kitchen for complete photo.
Can I do this:
1. Disconnect the range from the extension cord, trace that out and remove it.
2. Replace the original work box that is now a junction box, with an old work metal box, and then attach a metal extender box to the front of it.
3. Pull new 12/2 cable down into that box to supply the outlet to the microwave above and install a 20A GFCI there because there is NOT a proper ground.
4. Run flex conduit with 12/2 or 14/2 Romex through the cabinet from the new extender box to a new handy box attached to the side of the cabinet above the range, and install a 15A GFCI outlet there for the range.
Do I have to run a NEW power cord from the main box to the outlet for the microwave, and take power from anywhere else for a new outlet for the range? (to get it off of the fridge circuit)
Microwave consumption per its manual is 1650W which I calculate is 13-15A depending on system voltage (runs 118-119 here). I don't know if you have to assume 110V for max amps?
All this assumes the power cable coming into the junction box is 12 ga. If it's 14 then I can't use that for the microwave, but it could still supply the range.
I don't know what the other old cable is coming into the junction box. I can't find anything else that is off when I turn off that power at the breaker.
I would post this in the DIY forum, but it doesn't appear that I have privileges to do that.,
