SWA to Switch?

[Colin33]

Any suggestions as to how to terminate swa into a switch/fuse neatly? I've run it through a metal box and out to the switch with the switch cover covering the point where the sheath is split but wondering if there's a neater way to do things?

Set of very fine hole saws currently on sale in either Aldi or Lidl for a tenner

Yeah and after doing 2 holes they have less teeth than most of the chumps on the jeremy kyle show

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

Turn it into a figure of 8 and no problem

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.

Just use grommet strip then.

They should have that on the shelf

a heat gun makes it a lot easier to apply with the thicker stuff

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.

Our chippy swears by Lidl drill bits... and he normally moans about just about everything!!

personally I would rather have them coming out same hole.

ive got a 12-38mm cone cutter in bag so no probs for me with hole too small (if I need bigger then 52mm step cutters are availible)

Just on the top surface??

Poor technique mate

 

[NickD]

Just on the top surface??

It's just that it's easier to compromise the top surface because that has to be to IP4X or equivalent (can't admit 1mm dia object) other surfaces only IP2X (10mm object, British Standard Finger, oooh Matron).

Is your wholesaler a little bloke from Peckham with a battered old briefcase and a yellow 3 wheeler??

I really can't see how a wholesaler doesn't have 32mm stuffing glands on the shelf it's hardly a specialist item even the smaller ones in the more remote parts of the county I live in keep them on the shelf and no2 arbours and 32mm hole saws so I'd be very surprised if your local doesn't hold them in stock

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).

Tails through grommets as you describe wont be acceptable 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, 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....

Weigh the job up correctly at the quoting stage
Have the correct loose stock
Get a wholesaler who stocks basic electrical accessories
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!


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:

Even if I couldn't find a 32mm stuffing gland on my van, I bet I could find a 32mm bush and lock ring. Then use a couple of clips to keep the tails steady if needed.

1. the metclad sw-fuse sintra posted will almost certainly have 20 / 25 /32mm knockouts in the casing , you shouldnt have to drill anything.

2. you dont need 25mm tails anyway for a 63A supply..........
