So to begin with, I am not a DIY'er when it comes to electricity. I prefer to allow the professionals to handle these matters as it's not something I'm confident in and not too knowledgeable about... my dad however has always been a DIY'er and I'll give him credit that throughout his years he's done many electrical projects not only at home but also for the community. Lately, his mind hasn't been as sharp due to age and the potential for maybe even dementia so of course I want to check what he's doing. At their house they had a subpanel that was ran power from the main breaker box. Inside the sub panel, there was 3 breakers, which led power to:
an outlet in the "pump house", a small 3x3 almost doghouse looking add on, which is used for a small heater in the winter for making sure the water line doesn't freeze up
a single light receptacle which is used as a back porch light
a single gang receptacle which sits right next to the subpanel and is only used occasionally for maybe plugging in a shop vac when vacuuming out cars.
For some reason my father stated he needed to replace the subpanel and what not. He took it off and then decided that he would use a junction box instead of subpanel for this circuit. His plan is to simply connect the 4 hot wires with a wire nut, the 4 neutral wires with a wire nut, and I'm assuming the 4 grounds with a wire nut and place them in a junction box. I'm not too sure on exactly what works and what doesn't, I even recommended that I pay someone to do it for him, but he's always been stubborn and refused it of course. So I simply ask, is what he's doing even technically the correct thing or is it something that I need to make sure doesn't happen? Is there any method that I can at least tell him to do if his idea doesn't work because I am certain he will do something to hook it all up within the next two weeks. Thanks!
