I'm remodeling a kitchen. I need to junction 14 guage wires for a lighting circuit that are near impossible to get to or re-route. Is it permissible to junction 14 guage wires in the same box with a 12 guage dining room receptacle? Just to be clear, i wont be co-mingling 12 and 14 wires on the same circuit, im only junctioning them in the same box.
Also, I know the rules about how many wires can be in a certain box. I was thinking about using 4S metal box with a mud-ring to ensure I have plenty of space.
