Hi
I have a 3 phase cooker range to install on unbalanced loads 47a / 9a / 9a.
Apparently.... I need to confirm that..
it needs a new supply that is rcd protected.
My problem is the board that it is coming from is a old memshield board 3 phase with all individual bs88 fuse carriers and no main switch isolator.
ive not come across one of these before. Usually it's a new mcb in the board and job done.
looking on the fuse carriers they mostly say 30a which I'm thinking I can't put a 50a fuse in them so would I need a new carrier?
my original idea was to put an ad box mounted to the side of the board and bring tails from the 3 phases neutral and earth through to a 3 phase rcd/mcb set up.

50a bs88 fuses - rcd - mcb - rotary isolator - appliance

i have pictures of the board and fuse carrier but don't know how to put the pics on here..?

any help or guidance would be appreciated.

thanks

it needs a new supply that is rcd protected ,. why the need for RCD? is cable buried in wall <50mm?
My problem is the board that it is coming from is a old memshield board 3 phase with all individual bs88 fuse carriers and no main switch isolator.there will be one. usually below the DB.

looking on the fuse carriers they mostly say 30a which I'm thinking I can't put a 50a fuse in them so would I need a new carrier. need a pic to see if the fuse carriers will take higher rated fuses.
my original idea was to put an ad box mounted to the side of the board and bring tails from the 3 phases neutral and earth through to a 3 phase rcd/mcb set up. might be the best option. depends on above criteria

As a five week wonder (if you're not familiar with that term it essentially means that the electrical 'qualifications' you hold amount to the sum total of Jack all), at the very best you are considering taking on work here that is way out of your depth. It could easily be argued that by taking on any electrical work whatsoever you would be out of your depth, let alone three phase work in a commercial kitchen. Certain parts of your question demonstrate this quite succinctly.

You want guidance? Get a qualified electrician to carry out this work. Sorry to be blunt but it is quite clear that you don't have a clue.
 
thanks

Rcd- manufacture spec to install with rcd

still cant load any pics. i go onto reply and click on insert image and all it comes up with is "add image with url"

at the bottom on post permission it says: you may not post attatchments?

i can email you the board and carrier unless theres another way?

thanks

open up a photo bucket account, upload your photos to photo bucket, this will give your photo a URL, get this number and type it in when it comes up with '' Add image with url"
 
thanks ive managed to sort it..

Mate, don;t want to burst your bubble, or take the mick, if I was you I would get someone who knows what they are about to do this work as Mr Skelton said you sound a bit out of your depth.

not quite a 5 week wonder.. but i have been doing it for the last 5 years, unfortunately in that time ive not managed to see every type of set up of the 1900's and need to ask questions from time to time from people that have, hence me raising the question.
ive gone into detail about the proposed setup to give people an idea of what im trying to achieve. if i could of put the picture up in the first place then we wouldnt be here now.
i would rather know then presume.

I'm not here to argue with you, nor am I here to be disparaging towards you. Evidently however you are way out of your depth. Your lack of knowledge surrounding the existing set up is just the beginning, your design knowledge is poor at best.

You may well have been doing this for five years, that doesn't mean to say you've been doing it correctly for five years!

Seriously, this isn't a personal attack fella. Get someone who is qualified to carry out this work.
 
im not here to aruge with anyone, i was just after information on a distribution board that i have come across and a setup i was proposing with an unfamiliar board thats all.. maybe ive gone into too much detail.
