Wire Gauge for track and accessory bus #17

Open SteveBranton54 opened 2 years ago

Lot of chatter on the open chat suggesting the standard should allow 14 AGW wire on these buses. Need to at least take this question up and decide.

Our discussion 6/6 was to maintain the standard at 12ga knowing people will use substandard wire no matter what the standard is.

I think the intent should be to develop a standard that people WILL follow. 14ga makes sense for the Anderson PowerPole connectors, because the 30A terminal can crimp to either 12ga or 14ga. It’s also a roughly 30% cost savings, which isn’t insignificant.

12ga was and still is a good choice to address the voltage drop from the booster to the end of the bus. The following are really crude numbers using a voltage drop calculator. All of the following assume the booster is putting out 14V.
12 ga bus 300 feet long 9.2V at the far end.
14 ga bus 300 feet 6.4V.
12 ga bus 100 feet long 12.4V.
14 ga bus 100 feet 11.5V.
many assumptions and approximations are taken.
