Thanks, the metalclad unit is a good idea... for the SWA side, but what about coming out of the metalclad with tails? Through seperate 20mm knockouts perhaps??
And then on into seperate lengths of steel conduit? :smiley2:
Would you get two 25mm tails though a single gland?
Are you trying to wind me up. April fools was yesterday
I'm always a bit late...sorry. I'm still on the yellow book ;-)
I'm joking about the book of course, but I have to admit, the last time I looked at one of these books was during my half day 17th update all those years ago
Anyhow, that must be a massive gland to fit two 25mm's through! Surely too big to fit in a 25mm knockout?
How ever you you enter the box with your tails if they are exposed they need to be double insulated and restrained in some manner so any external movement on the cable will not act directly on the terminations... can you not terminate into a 25mm metal through box and bush it to the box running the cores straight through and tapping of the box for earth?
That enclosure will happily take a 38mm gland possibly even a 50mm. I would say you would get 2 x 25mm tails into a 32mm.
Oi Oi Oi ! Clueless... thanks cockney reject
I'm sure the reg for ferrous enclosures was still included in that version. The reg number in the current edition which you should be using is 521.5.1
Get out of it CR... I'm not defeated! If I was I wouldn't be here asking for opinions would I? I've seen things done in all sorts of different ways, so it's nice to ask how others deal with such situations, especially when you normally work for yourself and don't have a whole company of experience to draw on. I think my wholesalers only keep the 'Basics' range in stock so that's all I'll be able to pick up in the morning. I don't reckon they have a 32mm knockout either...so it may have to be a grommet out of a 25mm hole.
Turn it into a figure of 8 and no problem
Set of very fine hole saws currently on sale in either Aldi or Lidl for a tenner
No problem electrically with doing that but it's a bit unsightly on the outside of an enclosure. Also compromises IP ratings if on the top surface.

Yeah and after doing 2 holes they have less teeth than most of the chumps on the jeremy kyle show
Just on the top surface??
Me thinks the OP only wants to use bits he's got, or ripped off from another job, and doesn't want to get his wallet out!!

maybe he's a yorkshire man.
That's ma boy... spoil em I say!Tight but not that tight Mr Tel .. Ill have you know I folked out £5 quid on our lasses xmas gift ...Ohh and still had change for a pint ontway home!
Unlike some people, who think they know absolutely everything, I do consider myself an 'apprentice' most of the time. I can happily accept that there's always something new to learn. Particularly with electrics because it's not a full time occupation for me, and sometimes I come accross unfamiliar situations and seek to ask advice. Fortunately, there are some professional forum members who offer this helpful advice. Unfortunately, there are others like Mr. Reject who's comments are as useful as a fart in a wetsuit. What a pity they don't have anything more constructive to do in the evenings...TBH xt600 Given that you have been given various solutions that are neat and comply yet come out with various excuses from a wholesaler not stocking the basics to suddenly having no room to fit anything ... what is it you want from us then your a member of nearly 3 yrs and assuming from previous threads that your a practicing Electrician to the public although you give o profile details then you should be expected to first assess the job - quote it if required and get the correct gear .... if your lacking available room you may need to create more room or re-site the isolator (all this should have been assessed already).
Yes, been a member for 3 years of this and other forums, but rarely visit due to the condescending and patronising way some members treat others for simply asking questions.
Tails through grommets as you describe wont be acceptable
I would argue this point Mr Darkwood, surely if the IP rating is maintained what is the problem?? and your mention you rarely look at the regs book?... if this is the case how do you know if your work complies, ive been doing this job for 25yrs and advising on regulations on here for several yrs and I have to refer to it at least every few weeks, Which just goes to prove what an ambiguous publication this is. When the pen pushers who write this stuff and charge us £80 as often as they possibly can to read it actually write something that is universally understood by electricians I may just consult it a little more often! you mentioned running into a metal clad board through 2 different holes to fit your tails in and i genuinely believe you didn't realise this was a big no-no....Although I completed my training nearly 15 years ago this was actually one of the things i DO remember! I was just playing Devil's advocate...it appealed to my humour, but in hindsight maybe it was inappropriate.
Weigh the job up correctly at the quoting stage Fortunately I didn't have to quote for this particular job. It's a two year project. Things get changed or added almost every day so although it's a very interesting build (passivhaus) it can be frustrating at times.
Have the correct loose stock
Get a wholesaler who stocks basic electrical accessories I shall pass on this message to Denmans! As I guessed, they didn't actually stock a 32mm gland!!
Use your regs book more often.... having the 17th update cert' only shows you know about new amendments but it comes across you are less clear about other regulations.
Drop the excuses, always give a professional standard of work and keep a good stock of spares with you, having various grommets as what seems your only stock item is poor level of preparation you'll spend more time running around wholesalers and either cutting your profit margin or unfairly charging customers for time because you dont carry the basics ... 20 - 32mm stuffing glands should be part of your stock IMHO! Funny, but I probably have a lot more 'stock' than you do, but it won't be all electrical. Last week I was fitting a wet underfloor heating system, the week before I was constructing radon traps and laying concrete floors. This weekend I will be fitting an EPDM roof. Next month I have a kitchen to fit and some wood flooring to lay. And I guess you're now thinking of the old saying 'jack of all trades, master of none'? Well, I've been self employed for 26 years and never once had to advertise my services, my works vehicle isn't even sign written, and although ALL my work is through recommendation I have almost never found myself short of work.
I think I must be doing SOMETHING right, and the diversity of my job keeps me very happy indeed!
Sorry to get slightly off hand but you were starting to sound like a young apprentice always got excuses why they can't do what has been suggested ....take as constructive advice and not a rant at you :book:
