I'd love to, but too much grease causes my acne to flair up. Something I am sure you can appreciate.

i'm 100% with spin on this one. EAWR is statutory and so by law, an employer must ensure the safety of employees. this means that anyone using electrical equipment ( and that includes plugging it in ) must be trained,skilled or instructed. BS7671 is not statutory. fitting of RCDs in industrial/commercial situations is a way of improving safety, nobody will disagree with that, but they are not obligatory, except in the circumstances that spin has already outlined in previous posts.

Does a commercial install not need rcd protection if there are no special locations And no sockets for public use
(It's a car showroom)

Cable runs on tray then in stud walls

Cable in stud walls was my concern of doubt for the rcd

Mate its always the same on here, people quoting the regs, they should get there heads out of the green book, and try and think about applying common sense to the question.
Garage workshops and showrooms contain motor vehicles; they come in from the rain and snow, leaving puddles of water on the floor.
People will stand in the water with extension leads and who knows what in their hands
Not to mention electric car chargers
So what do you think about rcds ?
There are several other things about this sort of installation which are peculiar to them.
Be very carful of how you specify the lighting, because of colour rendition and it picking up paint blemishes.
If you want to PM me with details (don’t need to know who it’s for or where.) I will help you spec and price this job.

I'm assuming from your sobriquet, that you may well have worked as an electrician in the Navy.
Not being an Andrew myself, I don't have much experience of on board electrics.
Considering how much water is about on boats and ships, how many RCDs were fitted on the boats and ships on which you served.
Dare I ask how many people serving in the Navy have been fried because of a lack of RCD protection?

do they still flog sailors, or is that now classed as S&M?

We all understand the omission of RCD under skilled or instructed persons. But are you also saying that the >50mm does not apply? Because it reads to me that it will still apply no matter where the circuit is installed?


Great info though

Infinity, which Regulation requires that RCD protection be provided for cables concealed in walls?
What does it say?

have a look at 522.6.8., the first 4 lines.

Thanks your correct. I'm not sure why I had misinterpreted it like that.
infact I even have 522.6.8 highlighted in my book from the update course!
Infact 522.6.7 also covers it!

so basically an RcD protection for concealed cables is only ever required in domestic situations?

 

[telectrix]

usually, i would say yes, but imagine an office full of dumb blonde secretaries, pinning things to walls. in that situation, i'd be inclined to fit RCD protection to everything. each situation needs to be evaluated and installation completed using common sense as well as the regs.

 

[infinity]

Yes but dumb blonde secretaries are probably even more likely to hire a professional to hang pictures rather than risk a serious nail injury?

 

[Stroppy]

Skilled/instructed could be used in, say, a factory where the socket is restricted to authorised workers plugging in a known tool or load, but in a showroom where the public go, non-electrically-savvy office staff will be plugging in four-way extensions, computers, fan heaters, lit display stands, reps laptops, cleaners with their wet-vacs and God knows what else.... Far too uncontrolled to say they are all skilled/instructed.

The question should be: is there any compelling reason not to install an RCD? Such as the electronic testing lab situation.

bend a nail, you can hammer it straight again.

as a ship is really a in TN-C system RCDs cant be used on ships. the Hull is the neutral and earth. Well it was when i worked in the yards wiring frigates
Totally different regs see BGB Reg 110.2
