I see this model the on-delay is adjustable which is useful to prevent the supply bouncing
Is the 5s fixed delay-off time sufficient to prevent equipment damage , in general ?
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...

system is currently very much a WIP hence the janky mounting for the raspberry pi boards atm
eventually they'll be getting a case and another custom 3d print to secure them to the joist also
the raspberry boards are running of a tplink 5 port poe switch and also a decent cheap tenda unmanaged...
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

Any recommendations would be appreciated ? Been eyeing up both of these......

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...

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.

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...
