wiring harness power consumption/limitations?

Post by skinnay » Fri Aug 13, 2010 8:01 pm

So I will have about 80 12" strands of el wire around my tent, and now the most difficult part is making the wiring harness for this. I think I will have 4 main wires coming off the driver and all the other wires spliced into them. but some of the spliced extensions will be about 2 feet long and might be adding up to a fair amount of wire. Should I be concerned with any power loss with this amount of wire. I'm guessing the total harness will be about 200 feet of speaker wire with 80 plastic connectors.

The charge that lights up the EL wire is Alternating Current which typically does not experience loss of power the way DC current does. I think you will be fine if you are running your EL Wire Inverter at 75% capacity or less.

BTW I have no electrical training what so ever....Just an accumulation of knowledge from my nearly 39 years.

Someone will be round to help you in a more precise manner shortly.

In terms of power loss AC vs. DC is not really a factor. What matters is the amount of current. Higher current = more loss through the wire.

But EL wire is low current, high voltage, so loss through the wire resistance won't be a concern. Speaker wire should be fine.

Thinnest wire you can solder is recommended.

El wire requires minimal current. It is 110V, AC , 2 - 4 KHz.

I recommend Ethernet (CAT 4 or 5) or telephone wire (CAT 3).

Good luck soldering 160 hair thin wires. Takes great tenacity. I would never use elwire this way. Too many failure points.
