Was testing voltage for safe isolation on my multimeter today as I left my fluke t90 at home, however something strange happened.
I put the multimeter on voltage ac and then measured between earth then line, it sparked and tripped the RCD.
I can only think iv done something silly and wrong...
It came to light recently that electrium (own wylex,crabtree,volex,etc,etc,) and MK are supplying cooker switches,shower pull switches,dp switches etc built to a bsen number that's unsuitable for isolation according to the big green book! I spent ages on the phone and emailing trying to get an...
Hello I work as a maintenance man in a hotel that has recently been fitted with Greenwood Unity CV2GIP bathroom fans. These fans run constantly, full speed when the light is on and trickle speed when the light is off.
No isolation switch has been fitted for these fans other than turning off the...
Hello everyone.
I am due to take my practical exam for Level 3 on Monday but am totally unprepared. I seriously struggle to remember the safe isolation and testing procedures so literally ANY advice would be perfect right now.
Thanks!

Hello guys
I have an old 1960s flat i have carried out and EICR on, I have come across one issue i am unsure of:
the consumer unit is located within the flat with the meter adjacent, the only point of isolation is the Ryefeild panel outside in the communal cupboard.
Would the defect being no...
Hi Guys
Client wants 3 wall mounted under-the-unit sockets for washing m/c, dishwasher and tumble drier. There is a lightly used ring cct available above the units. He doesn't want 3 isolation switches above the units due to having a stainless steel splash back and there's no access below.
Is...
Anyone know of any safe Isolation lockouts that work on the new Hager boards?
My current ones don't fit.
The mini circuit breaker style ones don't work as the hager MCBs only have a hole one side.
The clamp on ones don't fit as the shape of the lever on the MCB and main isolator is curved on...
Hey guys,
My boss wants me terminating new supplies in a -48v d.c Distribution board. Easy enough but the board cannot be turned off due to critical load.
Now my question is this. Is it safe and or legal to work on live -48v d.c. and what would the consequences and dangers of possible short or...
Hello all
I am currently re wiring a flat which has a damp problem in the kitchen at the rear. I will be installing a 6" extractor fan with a pull cord on it to help reduce the damp. The fan will be supplied from the lighting circuit. I am aware that you need a 3 pole isolator when it comes...
Morning All
this might seem like a strange question but we are re-wiring a lot of kitchens where the kitchens will be ripped out the day before we start works, but they would like us to isolate the Kitchen Ring and cooker circuit before its ripped out as some points are surface mounted on the...
With the ease of EICR's and the like, and for customers to isolate those "buzzing" shaver sockets, isn't it time we started fitting them on isolator switches, either existing fan isolators or fused Spurs?
Can't believe some electricians still hang them on the live lighting circuit without any...

I'm sorry for all the Vid posted just thought you may be amused.
Hi, is there a max distance an fcu can be from an appliance ? Im looking to fit a wall heater on a dedicated circuit; I know the fcu needs to be near to the heater for isolation and maintenance ? I cannot find anything to define "near", in Reg 537.3.2 at least. Anyone know ?
