Thanks both. Even now it seems obvious that it's perfectly adequate to maintain the armour continuity - after all, it's designed to provide a good link to the armour. A case of too much thinking.
Yeah theres some good products out at the moment. I don't buy into every fancy new thing, but I've...
I think I'm being dim here, but it's been a long day and I won't be able to sleep with this rolling around in my head - so can anyone help me out?
Replacing 3x junction boxes outside, serving 3 external lights which have become waterlogged due to poor original installation.
The first two...
Is this a flat? Looks like MICC feeding a red-link, suggesting switch fused isolator may be available downstream - in a main metering or intake room etc?
It would be really fascinating to see some statistics on electrical incidents in the bathroom. My partner is European. Not having a socket in any bathroom in the UK is still something that confuses her. Schuko sockets in the bathroom are the norm is most European countries. Most the uses are...
Personally I love using them. But I don't always. It was said earlier that it's clear that they should be used on plugs - however, BS1363 makes it clear that 13a plugs are designed to accept flex, not solid core or anything else. So surely they should, by design, accept flex with no ferrule...
I mean ultimately AFAIK it's out of zones, so why not (in reg terms)? I've used the paper thin stuff personally in my house for one job - but I've laid the concrete over myself, and it's quite obvious that it's happened (and noted accordingly at DB) so I can't really comment on what other trades...
Just hypothesising here - surely more points of isolation introduces more potential for confusion as stated, both by homeowners and other trades?
I could understand the need in commercial where there's multiple controls, multiple room stats etc. But in a typical British house, if the main...
Again it's an individual thing - but my point is that crimps mainly seem really suited to stranded cables and are available in such varying quality that there's a lot of room for error. I think this trend should have been realised when 17th was established by wider study. At that point an...
Agree entirely - it's a real bone of contention for me that they were included in 17th as an approved MF joint. There's too many variables in the style of tool available to crimp them, to the quality of the crimp itself. I mean you can go to Halfords and buy some blue crimps - but I wouldn't...
@Lister1987 is correct. Line 3 of the MF instructions provided with a Wagobox specify that the lid should be secured with a cable tie. This is in the seperate section of the pamphlet on how to achieve MF compliance with the product
By changing the RCD to a 30mA from a 10mA you have changed the manufacturers design. You have also decreased the protection intended for the product. I would be contacting the manufacturer of the hot tub.
Interesting and sensible stuff. To be honest, I don't really like to work to the "like for like" clause generally anyway. Even on a simple job like this I check for a zs as a minimum - even if I'm essentially just changing what's on the end of the flex. Makes me sleep better at night.
Yeah, it's a complex area - which admittedly I wish to study in more detail. It makes me wonder though - if I had simply replaced it with a maintained LED fitting would that simply count as a "like for like" replacement and therefore just maintenance? Or does that not pass regards emergency...
With all due respect, I haven't given a full description of the layout, square metereage, number of external doors, use or type of building or area, the fire risk assessment for the building etc etc - because the question I asked was specifically about stacking fittings up on a klik rose, not...
Yes. There will indeed be 2 redundant roses. One of these can be converted to contain the permanent live. The question was more theoretical, as to whether that method would introduce any risks (as I've seen it done elsewhere - see below)
Indeed. The new emergency light more than satisfies the...
Good afternoon - apologies if I'm overthinking this, but I was hoping I could put this out there for consideration.
Scenario is as thus. Picture a small corridor, suspended ceiling with 6x 600x600 T8 fittings in the grid. 1x fitting is a maintained EML.
All fittings are fed from Klik roses...
As above. That light won't support that feature without modification. But for the price, it isn't worth modifying. Your solutions would be either
a) exchange it for an appropriate fitting that features override. I believe tinegaurd manufacture them.
Or b) install a regular floodlight with a...
Oh absoloutely (I can get into pretty boring in depth detail about 13a plugs!) I just felt it a point worth mentioning. I'm guilty of getting wrapped up in thought on a job and often find myself having to strip it back a bit when in a job situation.
Sometimes you need to simplify things I say. Is adding an FCU before a light switch make the situation dangerous. No? Does it break any regulations? No. Would it make sense to a future electrician? Sure, even if they don't agree with it. So therefore it's not worth worrying about IMO.
Crysotile was only banned in the UK for use in buildings in 1999 - so 90's isn't a safe bet!
Although as established previously in this thread if it's sparkly, more likely superlux. Fibre cement boards are often used in soffit too.
But yes - generalising it to "the 90's being safe" is a...
