Panel 302 Main Switch

[Lazy Pelican]

We have a 2006 B39 with a Panel 302.
I'm having problems with the shore power. I'm tripping the onshore power pedestal fuse, but not the main circuit breaker. It might be my shore power lead, which I've now rewired and checked continuity & it seems ok, assuming the resistance should be close to zero.

Does the ' Residual current circuit breaker F1' have a separate fuse, or is it just trip switch?

Any suggestions welcome.

OK it's sorted. We've moved location, so wether it was the lead or a dodgy power pedestal I'll never know.
