120 15 amp service ?
210 7 amp service ?
A 5kw or 5,000 watt heat strip will use 20.8 amps if wired to a 240 volt circuit. This would require a dedicated circuit using AWG # 10 wire on a 30 amp breaker.
Service entrance wire should be AWG #3 copper.
You need to look at the regulations that apply in your country. If in doubt, use a neutral wire of the same size as the live wire or wires.
6 AWG.
AWG 10.
As a service entrance wire you need AWG # 3/0 gauge copper.
If it's just a broken wire, you need the correct size 'butt connector'. Get the heat-shrink type, strip both wire ends, crimp on the connector, shrink the connector tubing ends with a lighter (BBQ lighters work really well). Done. If you need to add wire to make the connection, you will need at least two butt-connectors.

Need to know what the size of the wire is in the coil and the physical diameter of the coil.
depends on whether thermo used on gas or elec. unit, heat pump, strip heat, etc. red wire is hot wire. White wire goes to heat. yellow wire goes to outdoor unit contactor. green wire goes to indoor fan. blue or brown wire goes to reversing valve on outdoor unit.
You would use a set of wire strippers made for stranded wire and proper size. If the strippers are made for stranded and solid make sure you use the size identifications for stranded not solid!
Not that I have ever heard of. Electricity produces heat and heat is the cause of most electrical problems. The wire is heating because too much current is being conducted for the size of the wire. You need to either replace the wire with something larger or add another wire. The temperature of the wire has nothing to do with the coating, the heat is being generated inside the wire when excessive current is passing through.

No, example- If the wire is blue with a white strip, (which is your remote wire for the amp turn-on) the wire is blue, the strip is not the color.
To make a fused jumper wire you need a couple parts: In-line fuse holder. Solder. Soldering iron. Wire. Which ever clips you want. I used alligator clips. and heat shrink. What you want to do is take the fuse holder, Strip the ends back a little bit (Most of the times they come pre-stripped), next, take a chunk of your wire and then strip it the same amount. Once you do that, you need to solder them together (I typically twist them then solder them) Once soldered together, slip a piece of heat shrink over the end of the wire to cover the soldered joint, then shrink it with a heat gun or a lighter. Be careful as it'll get hot! Do that for the other side of the fuse holder. Then add your clips on the ends. With that, you have your fused jumper wire.
The wire size depends on the amperage, not the voltage. The fact that the welder runs on 440 volts does not affect the wire size! You need to ask this question instead: What size wire do you need for a three phase welder on an eight foot run if the nameplate amps are 45A?
Use AWG #6 wire.
