After reading most of the post on this site concerning what gage wire should one use, I was amazed that most say (from the fuse panel to devices) 14 gage. I have been in the low voltage wiring business for many years, and I do not understand, because, 18 gage is more than sufficient for even 24 volts, and that is a constant 24 volts, not momentary. If this was a higher voltage, perhaps 14, but it seems to me that purchasing 14 gage wire compared to 18/2 stranded wire is wasting money. But then again, that is my opinion. Heck, if you want to use 6 gage wire, be my guest. What I am really saying is, this is very low current, and the need for a thicker gage wire isn't necessary.
