Wiring help

Hi all

Trying to figure how to wire a air con compressor to an inkbird.

I'm in Aus so we use different colouring, but i'm struggling to even find what the colours represent (not even sure they're US colours).

As far as i can tell, red is live, blue is neutral and brown is also live? I think i'd also need a ground, any suggestions here?

Thanks
Hawk

For running motors you need a hot and neutral. In that three wire cable I suspect there is an unswitched hot lead (brown), a switched hot lead (red), and a neutral (blue).

Ground is used for safety - tying the chassis and any metal bits that can be touched to earth ground - and at least in the USA would use a bright green or green/yellow striped wire that eventually would be wired into the cable plugged into the power point. It would not be part of the controls to motors.

I expect you would bring the brown wire to one pole of the "cold" relay on your Inkbird and connect the red wire to the other pole, thus providing a hot leg that is switched by the Inkbird.

It would be most helpful if you could find a wiring diagram for that machine...

Cheers!

Thanks for the response, appreciate your help.

I was planning on wiring it to an Aussie power plug, which has live, neutral and ground, and use the inkbird which takes power plugs directly.

How would that change things? And yes i'm still looking for a wiring diagram (without much success).

Sigh, knew this would be a learning project, main lesson so far, know the system before.

Don't think i'll be able to find a wiring diagram. Furthest i could find was https://device.report/manual/7153427.

Looks like a no-brand unit so can't track it down.

Not sure if this helps but on reviewing the actual wired system, the red and blue wires went into the main capacitor, with the brown going into something plugged into the PCB.
