Should you use electrical tape on wire nuts?

If you ever find wires joined with electrical tape, or the wires are twisted together and then wrapped with electrical tape, get rid of the tape and join the wires with wire nuts. Never use tape in place of wire nuts—it's simply not secure enough, and it's vulnerable to damage.

How many outlets can be on a 15 amp circuit?

Technically, you can have as many outlets on a 15 amp circuit breaker as you want. However, a good rule of thumb is 1 outlet per 1.5 amps, up to 80% of the capacity of the circuit breaker. Therefore, we would suggest a maximum of 8 outlets for a 15 amp circuit.

How do you secure wires in a junction box?

If necessary, trim the wires as needed and strip 3/4 inch of insulation from the end of each wire, using wire strippers. Secure the cables by tightening the screws on the clamps, being careful not to overtighten and damage the cables. Plastic boxes usually have spring-tabs for clamps and do not require tightening.

Why do you not bond a sub panel?

So, why do you separate the ground and neutral in a subpanel? Because when we bond them together, it gives your neutral wire (the one carrying electrical currents BACK to the source) multiple pathways. That's how the chassis of some equipment will become energized.

Are wire nuts necessary?

Besides solder, if you want a good connection you need something that presses both conductors together with a very strong force. A wire nut does this, in fact the metal "helix" inside applies so much force it's similar to a crimp. The metal "helix" inside is like a self-tapping nut.
