Cu on floor

[m4tty]

Hi,

I've got a board to change on Friday but the current bs3036 board is about six inches from the floor. Is it ok to put the new board that low ?

Thanks

 

[Theorysparky]

yep

but i would find a wall to put it on though !!!!!!

Hi Matty,

more info needed

1. are you working in the seven dwarfs house ?

2. is the CU located in a cupboard

3. Is the cu likely to be accidentally damaged or messed with by children?

4. Does anything on your own personal risk assessment say that it should not be at that height?

Hi Matty,more info needed

1. are you working in the seven dwarfs house ? nope but able bodied people living there

2. is the CU located in a cupboard. Yep under stairs

3. Is the cu likely to be accidentally damaged or messed with by children? No kids there

4. Does anything on your own personal risk assessment say that it should not be at that height?

no.So all ok then. Cheers

i would have thought so mate, no less accessible than it was befor.

so unless they are willing to pay you to move to a more favorable location or your willing to do it for free then 6" from the floor it is.

i would say so anyway.

and

6" thats more than enough well twice what i have anyway

Just throwing it out there matty but if its existing then i would say its fine, if the cables are coming from above then bring it up but otherwise go for it, and if the customer is orite take your time explaining the rcd

 

[Robin Spark]

At least if the customer falls over in the dark when the lights go out they'll be at the right height to reset the cb or rcd

Matty if they are low like that and the cables come down I generally chop them out and lift them up a bit who wants to work that low off the ground especially when you get to my age. Good luck for tomorrow.

Thanks guys much appreciated.

Ive been round there today to do the pre-board change PIR/bonding runs and have come across a few things which I would like to ask you guys

Picture of board

1) Ive got 300mm widthways and 200mm height for the new board to fit where the old board is. Anyone know off the top of their head a board which will fit please. Or it may have to be put in vertically which will look abit poo. Other option is to build a backboard away from wall so it fits. Anyone got any thoughts on what they would do.

2) Lighting circuits up and down no earth. They have asked me to put a loft light and wondered if I could use a class 2 light fitting and come off the upstairs lighting circuit (no earth). They will be getting me to rewire the lighting next year as they want it up to scratch but moneys tight atm. All other fittings are class 2 so ill change put will put the usual sticker on board.

3) The immersion heater is on its own fusebox (one of them old metal rewirable ones) which is fed from a henly block in 2.5/4mm (imperial tho) which is dodgy. Is this the done thing in the olden days lol.

4) One of the rings fed one socket (the one top right in the picture) and it had been spurred off running all the sockets upstairs (4 in total) the spur cable is bigger than 2.5, id say roughly 4mm but more than likely old 7/029 or 7/036. As this is the upstairs ring i think ill put it on a 20A to be on safe side? good idea?

Ive got a few more but will wait abit as ill be writing an assay otherwise.

Cheers in advance guys

Mattyut the kettle on

Main switch with RCBOs, you may get a board to fit straight in then.

I could measure a 5way wylex for you tomorrow if thats any good,

I fitted it last week for the ASHP and PV.

 

[husky2013]

Just measured a 5 Way Wylex unit ( got a few new ones upstairs )the dimensions are : 190mm Wide, 300mm Tall, 200mm Deep at the widest point! hope that helps

 

[steptoe]

jeez Mrs St, the one I fitted last saturday is no way 8" deep or 12" tall,

what sort of one did you measure?

I would reckon the 190mm wide is about right though.

 

[husky2013]

apologies dimensions wrong way round

230mm tall

190mm wide

120mm Deep

 

[batty]

I would lift that up Matty just put a couple of noggins slightly deeper than the meter board fix a piece of ply or chipboard to that that way even if it overhangs meter board it won't matter then bring your cables in the back. If any cables come up I would just lengthen them.

 

[m4tty]

I was thinking the same as batty but wanted to hear someone else suggest it thanks mate.

Sorry I should have explained better the circuits in there are doubled up so total circuits will be 8 as getting rid of rewirable fusebox for immersion, wiring alarm into board so not plugged in to the socket the fuseboard is going to cover. He also wants a few spare ways for outdoor power etc.

Thanks again for your help on this one everyone. Much appreciated

I do the same as Batty, bringing cables in from the back. It gets rid of the problem of top-entry IP ratings on the CU.

 

[steptoe]

I have a few different sized boards kicking around I could measure over the weekend if its of any use to you,

back up to Grasmere(in the lakes) tomoz , so would be sunday before I get the chance.

raise it all up the wall to just under the socket, as said before mount a piece of plywood off the wall on some battens and fix cu to this. A new wylex 9 way board (with 1 80a RCD) is approx 290mm wide but a bit taller than your existing 6 way. Use joint box to extend any cables that need it and bring all cables in the back of board nice and neatly.
