What he said! Seriously, it's nice to see you here.

B32 MCB -> Socket -> Unfused RCD Plug -> flex -> 60 Amp MCB -> SWA -> CU -> B32 breaker -> ambitiously loaded ring circuit peaking at about 38 amps The weakest link failed.

The builder: 1 - removed some tails from a full 5 way Henley block to make room to power his new CU for the extension 2 - cut the end off his RCD plug (unfused) extension lead 3 - connected the flex to the switched fuse that powered a static caravan containing a hot tub, tumble drier, and fan...

Thanks - trouble is I did that last time! I don't think I have any old style left now.

I'm sure someone instantly knows... I have an old style 2 row mk grid box, with 3 switches on each row...the old sort with the metal clips top and bottom. To best of my knowledge these modules are now only available 2nd hand so I'm looking to change all 6 switches. Do I need to change the...

Thanks for suggestions. Yes it sounds like … a motor! I’m not sure yet how easily I can get to the other two but will see if I can compare heat next time. Every connection at motor, isolator and terminal block of panel seemed ok. I didn’t check the connections on the relay but will do.

Bit late to this party! In my area, Links and CEF generally have a tester day on the same day....and both then waste far too much time badgering all the sparks in the area to go to theirs. I play them against each other, got it down to £25+vat last year at CEF, and then I just take my main MFT...

Hi, I'd appreciate a bit of guidance from the industrial sparks here, I'm out of comfort zone! The setup is a wood pellet conveyer system with 3 motors driving an Archimedes screw, a vertical lift and another screw. I've been told the whole lot has run for 3 years without issue Last delivery...

Out of interest, was there a lot of PV in the immediate area? I had similar, and my suspicion was that in this upper class residential area a lot of early PV adopters without battery storage and lack of daytime loads was pushing the supply voltage up. I couldn’t prove it though.

To be honest, it’s just a light in a shed I’ve been known to overlook the lighting volt drop requirement as it simply doesn’t seem sensible since LED lighting has pretty much taken over. As you have said, the fact a customer could just plug in a light adds further fuel to the argument. When it...

I read the same but my knowledge of AC coupled battery setups stops at that Tesla thing…. Thanks for the reply.

Ok so next solar-newbie question - Can you use a hyrbid inverter without batteries connected? The underlying question is whether to get a hybrid inverter ready for the presumed addition of battery storage, or save a little money initially.

You need a micro-SD card. You put the firmware on it, stick it in the tester, turn it on, wait until it turns off, remove it, and off you go. I'm not updating mine this time until I finish a large testing job, but I've done it before and it was fairly simple.

@Phoenix - firmware 9.0.0 for X1 allegedly sorts out the auto-start of loop tests.

As mentioned above a clue can be whether a it’s an instant loud trip (magnetic mechanism) or takes a bit longer (thermal trip) If you are getting a quick mag trip then there’s a chance of a very very low continuity reading to help track it down. (Btw if it’s a glorious old Crabtree C50 board...
