[Rhodes22-list] Strange Electrical Problem

[Luis Guzman]

Let me add to that the wires have a maximum amount of current that they can carry. if you go pass the maximum, the wire will start heating up and eventually will catch on fire.

You always want to use a wire that is rated above the maximum current that your circuit will have, the same as breakers. Though you have to take into account the initial load of some circuits, like electrical motors, that will spike up when started.

Hank is correct in that a larger hose will carry more water which is analogous to the current, but this is at the same potential head (water pressure) which is analogous to the voltage.  Any restriction in the hose will reduce the flow which is analogous to the resistance.
