Question:

How can I splice 4 gauge electrical wire together?

I need to splice some 4 gauge electrical wire together to get a couple more feet, Are there wire nut big enough? or can I just tape it really good? What do i do?

Answer:

This is almost funny. What's your sign? Seriously, call an Electrician, or at least give me your girlfriends number so I can call her when you're dead.
4 gauge wire. .can I just tape it really good?. OMG. please call an electrician before you burn your house down or kill someone.
You need to get wire lugs. These are made for larger wires. Lowe's and Home Depot has them. Regards, Dale
The tape will not make a tight enough - solid connection. A loose connection will get very hot. #4 can carry a lot of amperage. Obtain some copper - split bolt - kearney connectors, that can be installed with two wrenches, It will have a divider in the center so each wire will be clamped individually, (must be tight) and wrap at least three wraps of a good grade of electrical tape - a large hardware store can help you.
you will need a split bolt (copper) and mastic pads. if indoor put both wires in a UL approved box 4-4 inches. MAKE SURE THE POWER IS OFF ! put both ends together in the split bolt and tighten. take a 6-6 mastic pad and wrap the split bolt / wires. then wrap electrical tape around the mastic area. this makes a real good connection and water proof.
