Faulty immersion heater, testing tips UK electrician. TIS MFT Pro 

Superb in depth video Mark. Almost had dejavu watching this. had exactly the same call out last week. Good stuff mate!!!👍

Thank you. Really useful video.... it's almost like being onsite and gaining experience. Appreciated. Just done a final ring circuit and practising the testing at college.

I did an eicr today which is prior to changing the consumer unit, it is currently a square D consumer unit with type 1 mcbs, ground floor sockets mcb had a ringmain plus 2 radials for 2 heaters (4 Lives), 1st floor socket circuit had ringmain and 2 radials to heaters as well, a right game trying to get them back in the mcb's after for the mcb terminals to grip all 4 wires... extra mcbs or rcbos required for the new consumer unit I'd say. Have to say I havent done an eicr for a couple of years nice to have a change

Nice one. Always useful, when was the tank installed always provides a clue about fault finding and element problems.

Don't worry i am not stalking you 😎 . Vids getting more interesting every time i watch.

What a really good explanation and informative vid. Just found your channel. Waiting eagerly for more. Thanks.

Mark whats the formula to work out what resistance you would expect on the element?. Cheers keep up the vids 👍

Good video. Thank you very much.

Hi Mark, Before you did the insulation resistance test, did you drain down the tank?

Sorry forgot tho thank you another for a great vid.

30 second job into 20 minutes you robbing bastard 🤣 Great video mate, I see this so often lol. Timer wrong, turned off, stat tripped most common things I see.

With doing insulation resistance tests at the element. Will it effect the timeclock which has an electronic circuit board?, unless you disconnected the load side of the time clock

Great video 😎
