    Extractor fan (60l/s) for kitchen wall

    Your pic looks about right. I would use a dp fan isolation switch like below. http://www.toolstation.com/shop/p86770?searchstr=fan isol Although 1mm cable would still be more that enough, if the rest is wired in 1.5mm I would keep it the same.

    Extractor fan (60l/s) for kitchen wall

    You don't really need one its just handy if you want to isolate for any reason. I always use a fan isolator switch when taking directly off the lighting circuit. http://www.toolstation.com/shop/p86770?searchstr=fan%20isol

    Extractor fan (60l/s) for kitchen wall

    Although I have seen people use a fused spur unit before, this is not required. Most use a local isolation switch, although again I don't believe this is a requirement. A 1.5mm cable is more than adequate to supply a fan.

    Hanging a light fitting from structural beam

    I would also imagine drilling a small hole wouldn't weaken the beam. Although if you did want to go around the beam, you can get decoratively coloured flex cable, bronze or brown maybe?

    Identifying timber frame construction

    Would this not be visible from the outside? Also try tapping the interior walls, you should be able to tell the difference between a solid wall and a stud wall.

    Changing garage door to door and window

    When i tried to do this on my own 1930's house, I checked with the local building dept and they insisted i went through building regs. He said that removing door access was inadvertently making it habitable. To comply with regs we had to install a sub floor and another skin of block work...

    Extractor fan (60l/s) for kitchen wall

    Well it doesn't mention backdraft shutters on the model he is looking at? I have seen alot of fans with no back draft shutters. I have a shuttered grill on my own house and it never flaps about.

    Extractor fan (60l/s) for kitchen wall

    Yes you would need the direct on model. Depending on the size of your kitchen and how much steam you produce I find that some times its worth investing in a larger model. Although these can cost considerably more. Yes a short piece of ducting and a grill is needed. A grill with shutters is a...

    Use shower cable for wall socket instead?

    The plug top fuses would provide the overcurrent protection for the appliances yes, However the cable and socket itself would still be protected by a 40A MCB. I might be wrong but i believe most twin sockets are only tested to about 20Amps. Its possible you could overload the socket without the...

    Schneider Electric SEA9AN18 Acti9 Isobar

    They do a dual rcd cu, they have these in the electric centre catalogue. The new Schneider domestic range is called easy9. Don't forget if its for a domestic property they need to be a fire retardant material, ie metal or enclosed in a fire retardant box to conform with new regs

    Removing section of a supporting wall in loft

    Haha 2020. Thanks again for you answers. The pic is quite deceiving, the chimney on the right has now been removed when the roof tiles were replaced so the wall is slightly wider than it looks. I would say the light switch is central on the wall. So strictly speaking, if I could come in 2 or 3...

    can i use these transformers for led striplighting?

    I doubt it very much, most LED's use drivers. Your better buying a complete new kit

    Use shower cable for wall socket instead?

    Looks like 10mm, but yes the cable often has the size embossed on it. Also you would have a 13amp socket protected by a 40amp MCB. Have you considered installing a small consumer unit on the end of this cable, then you could supply other things in the future?

    Removing section of a supporting wall in loft

    Also just to be clear, was only planning to remove approximately a doors width of bricks so I can walk through. Hence the perlins will still be sitting on a section of wall each, but was not sure if horizontal forces would push them inwards. Thanks again.

    Removing section of a supporting wall in loft

    Thank you for all your answers. I did think there would be horizontal forces in play. I'm even more concerned about having this guy do the work now! Not sure about any existing tie beams, I will have to look into it, however I suspect not. Where in the west mids do you live Woody? Don't suppose...

    Removing section of a supporting wall in loft

    Hello all. I have already spoke to a guy who specialises in loft conversions, but I'd appreciate a second opinion. Having just had my roof completely re-tiled, I'm going to have the loft boarded out etc. However there is a supporting wall, which the main joists sit on. This wall separates the...
