How do you properly wrap copper wires? We have been using electrical tape and it's melting the tape. This is in a camper, and it's in the electrical box. We're using this tape because the wires kept touching and arcing off of each other...I'm guessing :/
If the wire is not heavy enough it will heat up from the amount of current through it. If there is a short circuit somewhere, the wires will heat up regardless. It may not be rocket science, but it certainly is electrical engineering.
Shut off the power to that area. You have a major problem someplace other than in that box. You are waiting for a fire to happen so turn off the power and get out until the problem is fixed. Contact a local qualified professional electrician to do the work. That is cheaper than burning the unit to the ground.
It is not how you wrap the wires. It is how you connect them. You should use wire nuts or wire crimpers or splice joints. The tape is melting 'cause you are getting a loose connection and causing sparks. Once you get the wires tight you should cover the joints with electrical tape to keep the wires from touching any thing that they should not be touching..
