Help with Wylex board

[multimick]

Always fit live boards now mini rcbo no earth never had a bad one. spd built in if you want it

No difference drilling extra holes in back of enclosure to knocking out 20 mm holes in bottom and putting grommets in

Knocking out holes that the manufacture built into the design is one thing drilling new holes into the manufacturers enclosure is a completely different thing, but don't get me wrong, my original comment was said with my tongue firmly in my cheek,

So what do you do for glands or conduits when knockouts are wrong size/place?

 

[Mike Johnson]

Isn't that the same as cutting a board front cover to fit a different MCB or RCD to the manufacturers recommended, obviously the glands are not to the manufactures original design or they would fit without modification.

 

[Timbo]

Or when you have a board with no knockouts.
Oh, sorry customer, I've just fitted your new board, but I can't cut any holes in it for the cables to enter!
Get real, Mike.

 

[multimick]

Ha ha been away for a while but some things I don't miss

 

[Mike Johnson]

And the holes you have cut have compromised the board the manufacturer tested and fire rated, on the one hand others have suggested that you can not put a Hager MCB or RCBO into a Wylex board even though they fit without modifications, but we can drill holes and fit glands that are not the same as the manufacture used to fire rate and test their board, can we have it both ways? tongue still firmly in my cheek.

 

[westward10]

Consumer units are not fire rated they are merely constructed from materials which are not readily combustible.

 

[Mike Johnson]

But do the manufactures instruction that are supposed to be adhered to allow for modifications to the board?

I would have used plaster board rawl plugs, the metal screw in ones. Man, you've gone to a lot of trouble for the sake of a rawl plug ?
Or possibly screw a piece of ply on to the wall into the joists, it would only be a little bigger than your original board.

Drywall anchors far better imo. Like these

Why didn't you say they were umbrella or brolly fixings you were linking to

To avoid regional differences in what things are called. I should have called them hollow wall anchors. But if I ask for a box of dry wall anchors at a certain size and that's what I get. If I ask for umbrella or brolly fixings I'd get a confused stare.

Same as 100A Service blocks, we call them Isco's, you call them Henleys

If I asked my fixings suppliers for drywall anchors the response I would get is which ones do you want

The post that sparked this interesting debate, about regional variation of terms used for fixings intended for use on hollow walls, also included a link to the specific type of product being reffered to.

If you asked your suppliers for drywall anchors and showed them the image in that link, I imagine they would simply ask how many you wanted.

Some interesting reading on page 2 about knockouts.

some manufacturer have the same board but come with round KOs, square KOs or none at all, so you can drill what you need.

I would drill new fixing holes and have a good solid fixing to a wooden joist rather than use the supplied holes and possibly miss the woodwork in all four fixings.

Even brolly fixings can come loose if the plasterboard is the thin stuff.
