I'm about to upgrade the bullet connector pairings on my 3 motor phase wire leads and controller wires to Anderson powerpole connectors - as I have a few kicking about. Just wanted to check about the connector ratings ...

The controller's 30A (might run a bit more). However, is this much current drawn by each of the 3 phase wires or is that split between them ? The Anderson powerpole connectors I have are marked as rated 30A but I think that's more to do with the size of the crimp wire housings than the current carrying capability.

Nonetheless, would appreciate if anyone can comment on whether these connectors should be OK to use. They have to be better than than the ones that are on the controller at the moment, which are not very reliable seating together and the soft rubber housings over the bullets can get very hot.

The ratings are kinda a bit of a red herring when trying to work out what rms current is being used by each phase cos it's done by current / voltage block time rather than a nice conventional sine wave..... So go by the existing connectors size, if the new ones have a bigger connector area then they are fine
