Glowworm Micron 50FF - no electrical supply

Much safer to use a combi check type voltage tester (to GS38) if poss, gassafe.
Most multimeters have large exposed tips & poor finger guards etc. View attachment 17161

i like the long unexposed tips on a multimeter... I just googled combi check gs38 and it had those nasty 2mm exposed ends! Pfft... Can't shove them in the connectors and test for resistance & voltage etc...

I agree to a certain extent but you can always pull the tip covers off & pop 'em back on when done ,whereas it is very easy to earth out the long exposed tips if live testing with most multimeters. :bulb2: shocking !!

I find the tip covers to be a pita too and always pull them off then end up loosing them. I know it is a requirement but they are totally impracticle for use on a boiler. You can never get them in.
Decent multimeter leads have good finger guards and tips on them too.
Melted a few good screwdrivers undoing the lives on a spur and shorting it out on the earth directly above it:nono:

Get some proper gear fluke TL175 and crocodiles

U twist end and it's a long spike or short 1000v cat iv insulated probe.

Fuses blow for a reason, 99.9% of the time. I'd want to know why before replacing, otherwise you end up with a pocketful of broken fuses.

Ooh check out ermintrude & his fancy fluke case... That's an expensive extra that!!

Couldn't agree more, fuse is there to protect wiring therefore fault should always be found before replacing. As others have said anyone with knowledge of a multimeter should be able to identify and isolate the issue.
