Extension Cord Gauge Electrical Question...? Why do you need a larger evaluate cord when doing long runs?...
Why do you need a larger evaluate cord when doing long runs? Like Christmas lights for example, 8 amps worth at the end of a 200' run of 14 indicator cord. Besides the voltage drop, which I don't think would hurt the lights, how is it a sanctuary hazard? Please explain, thank you. :)
Answers: 8 amps on a 200' run? You should be using a 10 appraise cord. The danger comes when your trying to verbs too much amperage through the wire. Fire results when too much amperage travels through a rope. Amperage is electron flow through a conductor. If too much amperage flows through a wire, ample heat can be generate to melt and burn the flex insulation or surrounding materials.
electric wire is for electricity is what pipe is for hose. the heavier/bigger it is, the more it could carry. the longer the run, the more resistance is surrounded by the wire and therefor you requirement a heavier wire to compensate for it. hope this help
