Hi all, studying for 2391 and confused on disconnections times for TT systems
Now I’m comfortable understanding the disconnection times for TN systems that need to be met which is 0.4s and because the Zs will be low enough to cause a high Ipf to cause the MCB to operate within 0.4s… also from...

Back to the Men's Shed today to complete the installation of the 4 LED battens in the attic.
These were a joy to fit, having screwed the units to the supports yesterday and run the cables.
I pre-wired them, leaving decent Tails, because their location is tricky and overhead, so wiring them at...
Hi,
There are a few variations of this question here so apologies if its a bit of a broken record but I can't quite find the exact answers I'm after. Straight to the point:
Has anyone recently had a first time NAPIT assessment?
If so, were you able to show work in your own home? I know this...
I have read all I can find about radio 4 and tele switching, but can't find if this changes when our clocks change. It all started when I decided to get a smart meter fitted, and once fitted may as well get duel rate and recharge my 3.2 kWh batteries over night as well as using solar, this seems...
Hi Guys
Think it's time I brought myself a 'decent' punch down tool.
Any recommendations would be appreciated ? Been eyeing up both of these......
Thanks Sy

Hi everyone,
Long time lurker here, my project is simply my late 1800s house with various horrors hidden on every supposedly simple job.
Although not all horrors are electrical I do find this forum great for trusted reference when I encounter anything untoward and can usually find what I need...
Why is it that so many timers, programmable thermostats (and the like) are still manufactured without the ability to automatically change the time between GMT and BST at the right moment, despite being sophisticated in so many other ways?
OK, a rhetorical question and I know there are some that...
Hi all

Carried out a ZE test got 14 ohms and got same reading when did ZS on the board (yes did disconnect earth for ZE) .. the main earth is wired into the...
Hello,
as a relatively newly qualified electrician (mature trainee who completed his NVQ in 2023) today was the first time I've seen a melted plug. It was at a rental property and the tennant had a fan heater hanging on to what was left of the plug. I'm guessing that the fan heater had been...
Hi all,
Curious one and hopefully some one of you could give me some advice.
A customer has had a steeltech shed installed at their premises. A large one. Wants 3x light fittings and 5 double sockets intalled. There's an electric roller shutter door on the shed also to be plugged in. My plan...
Hello all
Well, been putting it off, but I need to upgrade my 17th edition to the 18th.
Not been a practising sparky for over 5 years, but I have been unemployed for 6+ months and hatefully... I'll have to go back to what I know (well, used to).
Not ideal but hey ho.
Found a couple of online...
Hi
I'm looking for some advice for adding a time delay on my parent's shower room fan.
My parents had a section of their garage converted into a shower room with toilet. But the builders did something a bit odd. They fitted a pull cord light switch by the door and then a separate pull switch...
Hello, 1st time post from an amateur. I have some old Habitat decorative lights that are powered by a transformer. There seems to be a break in the wiring as the lights go off when the wire is moved around so I was going to shorten the wire. The problem is that I can't find a replacement...
Autumn is now here, it's that time of year where the clocks go back and lighting control moves forward. A time when UK customers with gardens want to light up their outdoor spaces earlier in the evenings; meaning they'll be looking for new lighting and a reliable method of wireless switching...
Having to wire around a messed up output for a month or so. Some sort of program corruption is keeping the central lubrication system from operating at the correct intervals. I've never had to do this so I'm not sure which sort of On Delay/Off Delay setup could be used. But I need a 1 minute...
