Ooh upsetting the Admin3, not a good start!

Welcome to the forum BTW.

The Borg are pretty omnipotent, and frightening really.

Mind, could be Klingon, can't remember.

This will probably get me in heaps of trouble. ; (

Don't wake up Mr Smith.   :run

Are you asking what screws hold the lid on a conduit box? or what screws you use to fix it to the wall?

 

[kerching]

It is all relative to the substrate

I have fasten conduit saddles with 75mm wood screws and i have fastened them back with 20mm self tappers...discuss........10 marks

That is all well and good, but what do you use for the larger size conduit like 25mm?

Just doing someone elses homework

 

[Andy™]

put them every 150mm for 25mm

This is a question and a half this is ........on a scale of 1 - 10 on the Strange scale  , this is an 11 .

But I will attempt to answer in the in the finest tradition of this esteemed Forum and of course wearing my hat as the FSOTY ...Head of the Forum IT Dept

So :-  

A Bar saddle ...more properly called to a SPACER bar saddle requires a countersunk fixing .  The type depends on the material you are fixing to .  A WOODSCREW no smaller than No. 8 can be used and the length is variable for fixings into wood or into rawlplugs.

For fixing into steel etc again a c/sunk machine screw must used , a suitable size would be M5  or if you exist in a pre-metric world a 3/16 whit  or a 2BA can be used .  In my opinion the Monkeyman's use of M6 Rawlbolts is somewhat OTT  and should only be used to fix conduit boxes.

Now the easy one . Fixing a Consumer's unit ........anything you like.

Also easy , the box lid , assuming this refers to a BESA conduit box there are only 2 choices ...M4   or for pre metric conduit 2BA .

I wish you luck with your further studies, Mr Creative Maseratti

Hammerfixings ???

 

[roys]

If I understand what he means by a bar saddle, we use to call them hospital saddles, as they were used extensively in hospitals so that the conduit would sit well off the wall meaning less of a dust trap, or so I was told 33 years ago as an apprentice.

 

[Evans Electric]

I think you were told wrong Roys ..

A saddle is the basic arch shaped clip with two fixings that holds conduit flat on the wall.

A SPACER BAR saddle has a slim base and a seperate clip.

A DISTANCE SADDLE  spaces the tube off about 1/4" .

As you say , A HOSPITAL saddle spaces it well off the wall to prevent shytte  building up behind the tube , also used in food factories. 

After  many years in the trade I never heard of a BAR saddle TBH . 

But they could have changed the name of course as they do every few months with  EARTH WIRE .
