I would appreciate your input lads

Going to embarrass me self now as this is from memory but is it 1mm if on the top ?

Edit ; To be honest i wont accept any holes / gaps on a new install .

 

[Silly Sausage]

IP4X, <1mm

Would you use an insulated gland plate then?

 

[wade88]

Well ill be terminating from the bottom, and did my homework on eddy currents earlier and noticed the cutting slot between hole method mentioned so i think i will do it this way. Thanks fellas.

Tell you what though, i am DONE dragging that SWA around till ive had some lunch. Total calories burnt lugging that stuff around, 7689, need to get myself to greggs to get some good high fat calories back in me. Steak slice here we come.

Just be careful of the ip rating if you do go down this route .

I filled the slots with epoxy resin.
Width to equal plate thickness.

I would check the current that your bay lighting is pulling, as its going to make a big difference and might take 1 phase over the edge.is it 200 or 100 anp main inc fuses? Might be best to put a small 3 phase board there especially if you going to be loading the new board with 3 phase motors and maxing its load. What size swa you putting in?

This I felt looked poor,I'd have mounted the db closer to the trunking or trunked it in.Although with the amount of effort your putting in wade88 I reckon this will look great when finished.Not meaning to teach you to suck eggs but remember to do as much labelling as you can,it helps no end when you need to isolate or fault find.

We always use insulating boards entering/exiting metal switchboards and the like, for our single core distribution cables, which can sometimes be in multiples of cables per phase... Haven't slotted gland plates for donkey's years now, but it is a suitable and viable solution where your working on existing board/panel...

I've used both Paxolin and PVC sheet for glanding single core cables. It's a neat solution.

 

[Knobhead]

Both unacceptable under M&Q. We had to use metal.

 

[Silly Sausage]

Tony, only a brief explanation required...
Why are are steel lock nuts a complete No No?

 

[johnboy6083]

ill answer if i may archy, Using a steel locknut means that the eddy currents will be induced into the locknut, which will heat up, as will the gland, which will cuase cable insualtion failure.

Tony, why are pax and PVC unnaceptable in M&Q regs?

 

[Bobster]

M&Q state all enclosures are metal.

I havent done anything to the existing installation mate. That photo i took was just as it is. I will simply be moving the DB2 isolator to make space for my enclosure with the service blocks in.

My query was regarding the enclosure i have made, as there will be multiple cables entering and exiting of course, i had originally cut individual holes per cable (for the sake of tidyness) but as you made me aware of the high and likely possibility of eddy currents, i will now be employing the method Tony has kindly illustrated and cutting some the necessary slots between each 100mm section.

I will post up a photo of the finished job so you can all tear me to bits then
