Wire Size for Propane Solenoid

I'm going to run a new 2 conductor wire from the propane solenoid to the switch. The existing is # 14, the run is 25 feet or so. Can I go with #14? Thanks.

What current does the propane solenoid use?

Most are only 1 to 2A. The better ones will even drop the current once the initial latching has occurred, but they do vary a bit.

If the solenoid is 25 feet away ( so the total wire run is 2x25 or 50 feet).
A 1A draw will give a voltage drop with 14 gauge is 0.27v which is fine. If the solenoid draws 2A the drop 0.52v which is a little on the high side. I would use 12gauge if that can be fitted easily.

Check the current though it could be higher, which alters the calculations.

Ours draws nearly 2 amps.

It should be fine with 14 gauge. There are on line calculators that will calculate volt amps and distance to give yo wire gauge.

Re: Wire Size for Propane Solenoid

I have a similar run with #14 and serving me well with one replacement for a 27 year term. My solenoid was bad and I refit the wiring too, but not with specific need with any wiring problem.
