I'm going to install a few accessories on my motorcycle and also add an auxiliary fuse box. I'd be installing HID headlights (35 watts), halogen driving watts (55 watts) and eventually an aftermarket horn.

I want to run everything through individual relays and power each device directly from the auxiliary fuse box. The run from the fuse box is probably only about four feet, but I figure it'll take six or seven feet to snake everything neatly.

Is 14 gauge wire sufficient for this purpose?

I'll probably use 12 or 10 gauge to supply the fuse block itself from the battery.

TIA.

A 14 Ga. wire is capable of safely providing 25 amps of current. Your 35 watt device will pull 3 amps of current. Your 55 watt device will pull less than 5 amps. 14 Ga. will be more than fine for what you are doing with it.
