Evening chaps, wonder if you could give me a bit of advice. New member so go easy if I have posted on wrong thread!!!
Looked at a job today at a local golf club. The problem lies in the "green-keepers" section of the course. There is currently an existing 240v supply, fed via a 40a mcb, into a sarel box, which feeds a 3 way dis board, just a main switch, no rcd (!) and 2 circuits. I did not get a chance to have a good look but there are 2 13a S/S/O with flexes from 13a plugtops in the sarel box, running off in all directions (!) to feed 3 containers that have been adapted for lawn mowers and other grounds maintenance parafinalia.
It seems the 240 supplies some lighting, and some power within the containers. Now, this is all highly dangerous. So much so the local Health and Safety have been down and issued an ultimatum that the supply should be stepped down to a 110 volt supply, and in turn, to then feed any lighting and power requirements within the containers.
Apart from the sarel box, everything will, and at the moment is, exposed to the elements!!
My questions are as follows;
1) Is the 40a MCB supply ample enough?
2) What sort of tranny would you advise me to use?
3) Am I right in thinking the cable size feeding the 110v stuff needs to be increased due to the step down in voltage?
4) I assume a tranny can be left out in all weathers??
5) Cabling to lighting and power will be exposed?
6) Earthing arrangement?
7) Anything else anyone can think of??
Many thanks as this is going to be a MAJOR headache now the H and S have got involved.
