Subject: AeroElectric-List: Tyco W31 switch / breaker
From: Dj Merrill <deej@deej.net>


I am in the process of refurbishing the panel in my aircraft, which uses 
Tyco W31 switch/breakers for some items 
(https://www.aircraftspruce.com/catalog/elpages/pbcircuitbrkr2.php). I 
noticed that the W31 terminals are labeled "Line", which I presume is 
for the electrical bus, and "Load", which I presume is for the device 
being switched.

However, the person that wired this aircraft originally hooked them up 
backwards, with the copper bus bar connected to the "Load" terminal, and 
the devices being switched connected to the "Line" terminal.

My question is, does it really matter?

If it does, now would be the time to rewire since I have it all apart, 
however, the way it is hooked up at present does make for a neater and 
cleaner installation.  It has been flying this way for over 15 years, 
but if it is "wrong", then I should probably make it "right".

Thanks,

-Dj

It doesn't matter.   These are thermal breakers so current direction can run either
way.
