3% is an excellent design goal, and inherent in that calculation is the circuit design current, ampacity of the wire, the temperature of the space, and ultimately the fuse requirements. Numbers greater than 3% will work, no doubt for a while, but the risk is a runaway thermal reaction - as voltage drops, the current goes up, heating the wire, which increases it's resistance, which further drops the voltage, which increases current, which eventually burns the insulation and shorts. I've burnt up extension cords doing just this. I don't know why you'd want to recommend ignoring this.

Just when I thought I'd heard it all
Wow Hanley, just Wow.
Jeff, I admire you for trying to offer reason but you'll find the other side of the argument is belief based rather than proven physics and electrical engineering/design as set forth by the ABYC, NFPA and NEC and is not interested in anything those safety agencies have to say. Previously the belief based side has even advocated the ABYC is outdated and should be rewritten to align with the beliefs (don't hold yer breath waiting for that to happen). Anyway, thanks for trying.

I ran the motor fro many hours on a recent trip and the motor never stopped and ran very reliably.
Changing the pump with the moyer's kit and changing the fuel hoses was the right thing to do. |
