Question About Temperature Controller Wiring
« on: July 29, 2016, 12:12:14 pm »
I'm trying to setup a second temperature controller for my fermentation chamber to have a warmer heating up a carboy to warmer than the chamber temp (which is also used for serving draft) but cooler than ambient room temp. I'm using the directions here on the AHA site as I did before, but the computer cable that I had on hand and chopped up to pull out the wires is a little different.

Instead of the red, white, black, or green colors that I'm used to seeing, this one has white, blue, and a brownish-red color. I can't find anything online about what each of these might represent. My gut was brownish-red would be for grounding (earth color), blue for active, and white for neutral. Has anyone seen or had experience with this combination before?

when I have seen those colors on a bunch of Chinese made LED flood lights the color code I found was:

brown = Hot
blue = Neutral
green with yellow stripes = Ground

The white may be ground? 

I would have to follow up with the manufacturer to know for sure. 

That or use a volt/ohm meter to tone out what wire goes to what blade on the plug.  Wide blade is neutral, Narrow blade is hot and the third (round) blade is ground.

Hope this helps (at least a little).

It sounds like your talking about a power cord. your best bet is to grab a multi meter and ohm them out. if you dont have one you can borrow one or if your in a real pinch use a set of speakers to check just cut one of the two wires hook it either up across the plug and sound will let you know whats connected to what.

Brown/Blue/Green-yellow stripe are standard UK wiring colours.

Good to know.  I guessed it was standard somewhere but hadn't tried to look it up.

Thanks!
