Can mains Smoke/Heat alarms share the same electrical circuit in the domestic distribution board/consumer unit as an Intruder alarm under building regs/BS7671/ what ever regulation covers mains smoke alarms? Just seems wasteful to waste two ways in a electrical distribution board, not to...

It's hard to say for sure, but your description makes it sound like the left hand one was the feed to the pantry light/switch, the top wire was the feed/supply from the bathroom and the wire on the right hand side was for the switch for the light you have removed. But without seeing how it was...

Because my filter (see below) does not have a input afaik, only a output.

Ideally it should be screwed into the wooden studs, but I'm not sure where the studs are in the wall.

So the other day, I needed to remove the bleeding vent from my bathroom towel rail so I could pour in the system cleaning chemicals to it, having just isolated both valves at the bottom and then drained the water from it. First issue was the hive TRV valve decided to open up when the the...

That makes logical sense, but the way I read it, was the surge protection specifically contributes to the voltage drop.

So according to this article: https://www.se.com/us/en/faqs/FA158852/ Plugging a UPS into a surge protected power strip can cause more powerful equipment plugged into the same surge protected power strip as the UPS, to draw necessary voltage away from the UPS, causing the UPS to switch over to...

So like many people of my generation, I was taught how to wire a typic UK plug falling under the BS1363 standard when I was younger and have seen so many people wire/re-wire the typical UK plugs over the years, yet very few if any use ferules with the wire cores, whether it be the uninsulated or...

Agree it is hindsight not the best way to light the room, but how would you light a room what measures 6.8m long by 3.75m wide and has a kitchen island at one end with a cooker hood coming down from the ceiling.

Are you saying that you prefer incandescent and halogen lamps over LED's and CFL's? I would much rather 17 x GU10 5W LED spots in my kitchen diner than 17 x 50W Halogen lamps. (85W vs 850W).

And what's the lowest "normal" voltage one has seen in person?

Wow, that is high! Ever seen it above 253v?

So to set the scene, my elderly grandparents live in the rural Kent countryside and have had a APC UPS for a while as they live out in the country and get a fair few power cuts, and not only their internet/router but also there landline phone depends on the mains power being it's a VoIP landline...

So growing up, it was common to see alarm bell/siren boxes like the photo below. They are not so common today as far as I can tell. What caused them in the style below to go out of fashion and why?

Rebooting the panel fixed it (shame you can't do this from the engineers menu and have to instead physically power down the panel). I may still upgrade to the V11 panel with built in Wi-Fi and save the £72 a year I pay for the sim in the panel.

Hi all, since yesterday, my Pyronix Enforcer 32-WE alarm at home (which uses the Digi GPRS SIM module) has not been polling according to the Pyronix cloud, yet I can still send and receive SMS messages associated with the GiffGaff mobile number associated with the panel. Has anyone seen or...

So many would likley have seen you can buy shaver sockets that include built in USB charging sockets. Question is, when such a shaver socket is certified to EN 61558, does that certification apply to the whole unit with USB sockets (and thus suitable for use in zone 2 in a bathroom) or only the...
