Hi,
I want to trigger the main power relay in the boot from the ignition switch on the dashboard a distance of 4.5 meters. (14.7ft)
From the Internet I've found this:
'The current draw of the coil is not normally shown but is typically 150-200 mA.'
Using wirebarn's voltage drop calculator.
Entering:
13.8v,
1amp current(instead of 200mA)
wire length of 4.5m 14.7ft
=22 awg.
The question I have is. Even though the calculator requires a cable of 22awg do you think that it's best to up the cable size 1-2 sizes or leave it like it is?
Regards
22AWG will be good enough to trigger a relay at this distance.
It'll depend on the specific relay, but that should be fine - it you can post the relay in question, we may be able to find the minimum operating voltage.
Hi,
Thanks for your reply’s.
Gord, I intend to run micro relays like in the attachments. I hope that helps.
regards

If the relays are reputable, you should be fine.
