Two basic types are available:
Thought of this is to let others know on what's going on how wires are connected regarding multiple outlets Short answer: Unless you are really loading this circuit heavily (~16 or more amps) you will be fine. There is no limit to the number of boxes or splices, only a length limit. In the specifications of most of the commercial and industrial jobs we wire they require an increase in branch circuit wire size if we exceed 100 feet.For a Wire Junction Box, you need to power the metre at the bottom of the puzzle until it sits between the blue bars. They're circled in green on the diagram below.
One may use this table to determine the safe wire capacity for junction boxes. For example, how many 12 wires in a junction box? If it is a square box with the dimension of (4 X 1 1/4) inches, then 9 wires of size 12 can be fit in the box.
