One of my customers has asked me to enlarge a loft hatch. The house is 1920`s with an old syle roof (made in situ). Does the loft door need to be fireproof ? would 10mm MDF be ok ? I dont want it too heavy. I will need to remove part of one joist , but of course, this has a strut/hanger on it...

Heres the RCD/ Fuse spur http://www.greenbrook.co.uk/proddetail.php?prod=M92W

I am about to fit a fan heater to my father inlaws bathroom. I have fitted an RCD fused spur from the upstairs ring main which ran through the airing cupboard (outside the bathroom) which will feed the fan. Do i need to fit an aditional switched fused spur adjacent to the appliance(as requested...

Should be no problem. It`s only a matter of measuring the resistance of the primary supply and load supply cables. I have a resistance meter that conforms to 16th edition regs. eg 200ma pass current.

Yes the airing cupboard is outside the bathroom. I would just need to run the cable for about 1.2 mtrs through the loft, then down through an internal cavity wall (about 300mm) to the heater.

I do indeed intend to use the old immersion cable as the fan supply. It seems ideal, as it terminates in the airing cupboard just feet from the fan position. So I was going to use a double pole isolater as a junction box and extend out to the fan .

I was trying to keep the work down to a minimum so would be utilising a redundant immersion supply.Therefore I didnt realy want to get involved in too much wiring. The bonding is up to date at the supply and uses 10mm cable.

I am fitting a new IPX4 rated fan heater in my father in laws bathroom. The consumer unit is an old Wylex fuse type, so I was intending to fit an RCD in its own enclosure adjacent to the CU and feed it from a spare 15 amp fuse. The fan heater will be cross bonded with 4mm earth cable. Would...

Thanks for all the advice. You are quite right about the incoming supply fuse. This was 60amp feeding the Wylex board. I have already had the electricity supply company out and they have uprated this to 80 amp

I am fitting an electric shower for my father in law. I have notified building control and wish to comply with the law. The consumer unit fitted at the moment is an old wylex fused type. I intend to fit an additional shower consumer unit with dp rcd and 50 amp mcb with its own 25mm tails. My...

Hi I need to replace an unvented water heater in our village hall. Does the new unit have to be WRAS approved as I was going to get a Heyco one which does not have this rating. Can anyone advise?

Hi I thought as much, its just nice to have conformation. Thanks for the prompt reply. Cheers

Hi I intend to make a new front entrance to my 1980`s bungalow . I will be removing an existing double glazed window and substituting it with a upvc front door and smaller window. I wish to leave the original lintel, so my height is restricted to about 2055mm. The door I have chosen is 900mm...
