    Bosch oven in Germany needs wireing

    I have met this combination before. It was a pair of appliances (oven and hob) designed to be connected together internally (by way of a special plug and socket) and only one electrical feed was taken to the oven. The hob then had its own feed directly from the oven - either single or 3 phase...

    Over-run extractor to come on same time as shower

    Could it not be incorporated into the DB? Then run a new feed from there to the fan or light or whatever this thread was about now!! Otherwise, a 2way DB outside the bathroom could be used.

    ...Which floodlight?

    I have experienced the fluorescent lamps designed to replace tungsten halogen - they appear to be fine when left on for longish periods but do not like being switched on and off using a PIR. As you don't have any, just a switch then I would use those. Light output is probably equivalent to 150w...

    Over-run extractor to come on same time as shower

    I'm sure that is correct - all line conductors must disconnect at the same time (on a 3 phase supply) - that is why although a motor could be protected by BS88s or 1361s or similar, it must have an overload relay which allows this to happen. Of course in a single phase installation, only the...

    ...Which floodlight?

    Unfortunately it is difficult to satisfy all of the factors you describe. Assuming you still want to replace the floodlights then there are a few alternatives. If you want to keep the existing then there are a some factors which would help. The lamps themselves MUST be horizontal - so no...

    New Kitchen extractor wiring install

    Presumably the timer is so that the fan will stay running for a pre-determined length of time after you have switched the light off. If this is the case, it sounds unusual that it has humidistat control aswell as the fan would normally be switched on when the light is on. If it is the case that...

    What size RSJ?

    Thank you for the replies. I too have had a busy week and only just managed to get back on here. I have priced a 254x146x31kg and I will most likely put one of those at ridge height. I will also be putting one above the door on the inner skin. From what you have suggested, I expect this will...

    What size RSJ?

    I realise that may have sounded a little strange! It is a "standard" garage (if there is such a thing!) of 7.7m x 4.1m with walls of 3m high to eaves. In the rearmost part, I have made provision for some storage at a height of 2m from floor, extending from rear gable by 2.4m. This will be hung...

    What size RSJ?

    Thanks again for the reply. I take on board what you say about the full length of 7.4m. If this was reduced to 5.4m then the difference in size would be so much? In that case, if I change the goalposts slightly (again!!) and had the 5.4m still at ridge height but ending at 2m from the rear wall...

    What size RSJ?

    Thanks for the reply - very helpful! Just to clarify as I'm not by any means an expert in this field(!), a catnic would suffice for the roller shutter? I wasn't sure they were made in that length. Assuming I wanted to use RSJs - just to complicate the job further(!) I was hoping to fit my...

    What size RSJ?

    Thanks for the replies. Although "messy" as you say, a column in the centre of two widthways beams would be ok. I would like thelift at the front doorway to assist with moving objects into the garage and engine lifts at the doorway. In addition, I would like the lift at the back of the garage to...

    What size RSJ?

    You're right - I expect it will be silly money!! The width is 4.1m to outer skins. I was thinkiing about using the width for the lifting gear but the full height isn't available then! Any suggestions?

    Wiring a generator for backup power

    I used to connect my 110v tranny to a 110v supply using a lead with two 110v plugs on it. Then I plugged the 240v plug into a double socket and used the sedcond outlet for powering my cordless drill battery charger and radio. Works very well on a 110v only site - just smells a bit "fishy" when...

    What size RSJ?

    Hi. I am a newbie to this forum so please forgive my questions if they appear basic! I am in the process of building a garage using 4 inch solid concrete blocks with a 2inch cavity (so double skin). I am approaching the time to fit the 2 lintels for the rolloer shutter but am a little unsure...
