Pig tailing two hot leads


Just installed a motion light. I want to tie it to an existing hot lead for pig tailing it, one wire, to a 20 amp breaker. What is the right way? Twist nuts, crimping together and taping. We can tie two hots together with pig tail so we have only one wire going to breaker? The motion light will be tie in with a 175 W mercury vapor lamp on a 20 amp circuit.

This is my first thread and I will appreciate the help. Thanks in advance.

wire nuts (or if you are in Canada, apparently they call them Marettes (I think))

yes and you will have to do the same for the neutrals as well.

Normally it is easier to tie in the new (motion) light to the existing (mercury) light at the connection box at the latter.

You should not break into the middle of the cable going to the existing light unless there is more than a foot of slack in the cable since you must cut the cable in half and put both ends into a junction box with at least six inches of each end inside the box. About a quarter inch of the cable jacket should be visible inside the box after the cable is fastened in place; remove the jacket before inserting the wire ends into the box.

The pigtail itself is a short length, perhaps six inches, of wire used to help connect wires that don't reach, or to avoid trying to put two wires under one screw terminal that can only hold one wire. Most likely you won't need a pigtail when connecting together the wire to the mercury light, the wire to the motion light, and the wire going back to the panel for power/neutral.
