A 1.5 mm wire is rated at 13 amps at 120 volts.
The earthing wire does not normally carry current.
No. The larger wire can carry more current.
what is the current carrying capasity of 16mm cable
It has to with the fact that when voltages go higher the current goes lower. The lower the current a device draws, the smaller the wire size needs to be to carry that current.
The neutral wire does carry current in a closed AC circuit. Clamp a clamp on amp meter around the neutral wire directly after the circuit load and it will read the same current as is on the "hot" wire.
15mm approx.
The earthing wire does not normally carry current.
As with any electrical installation, the wire size used depends on the expected maximum current the wire will carry. That cannot be determined by voltage alone.
No. The larger wire can carry more current.
Wire gauge is used to determine the size wire needed to carry the correct amount of current for the job. It must be sized appropriately for the current in the circuit you are building.
The wire size is large enough to carry the load current and that the cord is properly voltage rated.
what is the current carrying capasity of 16mm cable
The current caring capacity of a wire is based on the physical size of the wire. The larger the diameter of the wire the more amperage the wire is allowed to carry.
It has to with the fact that when voltages go higher the current goes lower. The lower the current a device draws, the smaller the wire size needs to be to carry that current.
An electromagnet isn't designed to output any temperature. If it does that, then you can be sure that the size of wire from which it's wound is too small to safely carry the current it is carrying.
Wires are sized depending on the amount of amperage they are expected to carry. High current required a large size wire and hence small amount of current only needs a small wire.
Couple of things wrong here. 30 isn't a wire size. If you mean a wire that can carry 30 amps that would be # 10. Now it depends on how many # 10 wires you want to put into a conduit that governs the size of the conduit.
