Hi, I'm a new DIY member hoping to get some suggestions on a (to me) perplexing problem with my basement overhead lights. There were originally 4 of them, and through the years, I've added 4 more by running cable from the existing fixtures. They are all controlled by three 3-way switches which...
Fault finding. Good to systematically and logically investigate the problem, then the culprit has been staring you in the face...
phone call from new customer- no power.
get there, split rcd board. “It’s that big switch that won’t stay up”, says the woman
Ok, the rcd. Unplugged everything I...
Have been to a farm today that has a 100mA time delayed RCD main switch covering a DB that has MCB’s on majority of circuits ( less than 32A) and 30mA RCBO’s on sockets, lighting etc.
What I was thinking was does this comply with regs as circuits less than 32A should disconnect in less than...
My guys were testing a 500ma time delayed RCD today with our Fluke tester, can’t remember the model, 1556???
I had a go and couldn’t get it to trip either. The tester was set to time delayed setting, 500mA, did the 30s countdown but didn’t trip. Am I doing something wrong?? And yes I was...
I asked my wholesaler for one today only to be told they're discontinued. A quick google of MK 6400s seems to confirm this. Does anyone know why this is and if Mk are producing a new version for some reason?

If anyone has time to explain how time-delayed RCDs function, or point me to an article that explains it I'd be very grateful.
I understand the principles behind a standard RCD, just very curious how that same design can then incorporate a time-delay.
Many thanks,
Could someone who uses this software tell me what the Rated Time Delay box is for when filling out the Main switch/ Switch-Fuse/ Circuit-breaker/ RCD section of an EIC?
Is it for the recommend range in which a time delayed rcd should trip 130 - 500ms... or is it something else?
Hi People,
Carrying out a EIC on a recent cu replacement on a TT system. 100 amp 100MA time delay RCD used up front but cert is asking for time delay in MS- how do i find this out?
Thanks

I have been asked to install a time-delay switch for the car park lighting at our village hall.
At present there is a single (2-pole) switch inside the building which controls the outside (bollard lights). However, when closing up the building on dark nights, once the bollard lights have been...
Hi all, just wondering if anyone with a lot of experience had any thoughts on this;
I've seen on farms that are usually tt earthed the mains come in and through an s type time delay rcd and then sub mains go to different buildings which are protected by standard 30ma rcds. Sometimes faults in...

I'll eat my hat if this ever gets going!!!! The coalition legacy will be more nuclear and some vague promise of carbon capture - everything else will have been binned!
