Hi, I want to connect a switch to the remote bridge of my phoenix inverter 12/500. Which cable size should I use (distance between inverter and switch approx. 1 meter) ? What is the current flowing trough the bridge?
I cannot find this in the manual.
It's a very low current signal, so 0.5mm² would be just fine as would 22AWG.
If it's too small the jaws of the connector might not grip the copper properly, more of a mechanical problem than an electrical one.
I think this is quite an old model. (Just checking I found the correct manual.)
Most of the remote switches are very low current and not particularly affected by wire size. Given the short run I'd be surprised if 0.75mm wire is not sufficient. Ideally put in a wire and measure the current with a meter. It's probably a few milliamps.
