New circuit for Utility room.

[Megaohm7]

Been to price a job where a customer is having a utlity room added to his property. I have looked at the existing C/U and it is a wylex with BS3871 mcbs and an RCD main switch. Earthing arrangement is TN-S and earthing conductor is 6mm and there is a 6mm bonding to gas. I was thinking about Henley block and a seperate C/U for new ring and lighting circuit to the utility room. The bonding would be upgraded too. I have suggested updating the original C/U but customer only want the new circuits in the utility room. I would only be responsible for the new circuits that I install which would be highlighted on the certificate.

I would not bother to take two separate circuits to the utility room, the lighting and extractor fan could be spurred off the radial, or ring, through a fused spur. This way you could use a simple main switch and rcbo set up, separated from the main cu through the henly block. Your EIC will only be for the work you carry out, and should be as detailed as possible to ensure your only liable for what you have done.

Thanks Manator, That's a good point and also I need to sort out a sufficient extraction fan to suit building regs. Makes everything simple too.

Sorry to butt in on your thread mega but who's responsibility is it to ensure an extractor fan is fitted. If the customer doesn't specify an extractor fan and you do the job as per customers instructions, who's breached the building regs? It would be the customer?

that will be the customer then

but mega should put this on the cert and suggest the consequences of not having it

but then if there is no sink or toilet then why need one ?

A moot point re who is responsible - if you fit a spur/isolater for a fan with fan to be fitted later then it could be argued that you being the professional should advise the client re Regs requirements/ if you fit a fan to existing fan that did not meet regs then likewise it could be argued that you should have advised. Doing this would be your protection, maybe never needed but for the effort easy life!

Most of these probs are not new - easy option - advise - we should all be in possession of the relevant info.

Get a copy of 'Guide to Building Regs for Electricians' same format as OSG. when you can advise/enlighten it sure makes you seem knowledgeable in your clients eyes.

Al depends if its under building control if not you can't force them to have one if it is they won't get it passed unless they have one.

I've got the electricians guide to the building regs ( green book ) and I will look at it later but I will advise on an extractor fan

I've wondered that! because an appliance you would have in a utility room, most people would have in their kitchens and as far as I know there is no specific requirement to have an extractor fan in the kitchen.

No requirement for extractor fan but some ventalation is required be it an extractor or cooker hood that vents outside recirculating ones are not sufficient.
