During the later days of my apprenticeship and early days as an Electrician, I was sent to report to the Electrical Foreman on the site of the now Hilton Hotel in Bath, my task "Bond all the Bathrooms on the site H to C to Bath with no testing in those days, got quite fast at it towards the end...
Hi all.
I am seeing different figures here all over the net, table3a (p363) states a 30ma RCD has a trip time of 300ms max.
So at 5x is the maximum 60ms? I seem to recall 200ms and 40ms for a 30ma and these are the figures I am seeing over the net...
Please I just want the correct figures for...
I really hope that someone can help! I've watched some YouTube videos and searched online but nothing really helps.
We have a Hortsmann VMK 7D SRS, in a rented property.
What I need to know is:
* What time is the cheaper rate (economy 7) set for
* Do we get an extra cheap rate boost between...
Hi have 60947-2 Main Switch with added 61008 with settings for mA and mS, now come to test and it’s set on 300mA with delay of 0.5 so 500ms, now what I’m wanting to know is: 500ms is the maximum tripping time for a S type RCD, so what’s the point in having more settings as this has a variable...

Hi, my daughter has a mitsubishi colt 1.1 litre 56 plate. Her car beeps 3 times and then changes the radio station. This has baffled me. Does anybody have any ideas please. Thank you.
What is the reasoning behind having a 0.8 disconnection time for up to 120 volts Uo, but it then jumps to 0.4 seconds as soon as you go over it? Wouldn't it be better 0.8 seconds for 150 volts Uo and under, 0.4 seconds 150 volts and over Uo?
Back when I started out a simple board swap to a nice new plastic 16th Ed split board would set you back £400 all in including labour , maybe even a bit less.
I have just seen a quote from a well know utility provider for a consumer unit change for £1656.82
WOW
Evening, just revising for 18th update course and wondered if someone can just clarify something. (I might just be confusing myself, too long staring at the BBB)
Reg 411.3.2.2 ii) does that also include luminaries?
I understand 411.3.4 applies. Do notes 1 & 2 of 411.4.4 mean that the use of an...
Could someone shed some light on the following please?
411.3.2.1 implies that the 5s / 0.4s disconnection times only apply to earth faults. I've not found anything else in the regs that suggests they apply to short circuits.
435.5.2 says faults should be disconnected before the fault current...
Evening all, happy Friday!
On the new forms there is only one column for RCD disconnection times.
I understood you would just record the highest of the 5x readings but on looking around to confirm I found this article on Professional-Electrician:
"The model forms in Appendix 6 have been...
My niece has a 2004 Mazda Tribute with a strange air bag light problem. She can make a 40 mile round trip without the light coming on if there are no high load devices on, but if she turns on the heater or lights the air bag light comes on a few seconds later. To me this means the problem is due...
Hi everyone, long term visitor to the forum but first time posting a question... be gentle
This question is with regards to the changes to the 18th edition certificates, which only require one disconnection time recorded.
When recording the highest value taken when carry out RCD tests, Reg...
Hello everyone. I installed a new instruments panel with a tachometer for my old car (Fiat Uno) the board is for a Fiat Palio but the connections are the same and the panel fits perfectly. The only problem is the tachometer, it displays 4000 rpm when the car is turned on but idle, and goes all...
I don't know why I've not noticed before but the disconnection time for final circuits greater than 32A is 5 secs on a TN earthing arrangement. Does that mean a shower has a disconnection time of 5 secs? Although this circuit would also fall under protection of an RCD??
Also, cooker circuits...
I'm trying to find a list of trip times for 30/100/300/500ma rcd devices to make some flash cards.
I've found table 3A but it's somewhat confusing. If I read it correct, the table suggests a 30ma rcd should trip at 10ma. I must be reading it wrong?
Anyone know how to read the table correctly...
Could anyone confirm if we test 100mA RCD's at x5?
There is a lot of information on the web that says you only test at x1 but Table 3a in appendix 3 clearly shows a max disconnection time for a 100mA RCD at x5 to be 40ms.
Thanks all.
Bought a new little Cudis metal DB the other day.. on the circuit labels they now have CAR CHARGER.. the first of many I'm thinking!
Have many sparks fitted any of these yet and what have been your experiences?
I've done one for myself, just like a new cooker circuit really.
I believe the...
