depending on the size of the extension you may be able to do it under your personal development rights (PDR), in which case you will not need any drawings. you can do some yourself if you like, i used excel of all things. you will however need a structual/architect to work out the loadings as a...

im not sure if you understood my post. normally you would run a 10mm earth for the water and then another 10mm earth for gas. however it is acceptable to run a single 16mm to the water and then the gas(or viceversa) as long as the cable is continuous, ie not cut/broken anywhere including the...

im not sure what you mean m8 :) you do not need the 3rd core, it gets disconnected at both ends. the armoured is protected by the armour sheath which should be earthed at the house cu but isolated from the shed cu. basically you are feeding the shed as an tt arrangement. why is every opne...

hi m8 as far as i can remember the earth on a pme system should not leave the building. you need to put an earth spike in for the shed and just supply live and neutral, so 2 core swa would be fine. use 16mm from shed cu to earth spike. disconnect earth from house cu end. hth matt

hi it does sound like a possible neutral problem, this sometimes happens if an protected neutral is in the unprotected side, but if its intermittent id rule this out. the appliances that trip the rcd, try them in the garage to see if they do it there. does the garage have its own earth, ie...

No internal doors are to be alarmed. everything is chased, there are no visible wires. if i have no contacts i cant have any protection through the night, or am i missing something? i have quotes from installers but they are far too expensive compared to what i can put it in for, being an...

hi guys this is a fantastic idea. we are in the process of buying a property and our homebuyers survey has picked up on a few things which we were not aware of. if we pull out now we'll lose about £1000 of which about £600 was spent on surveys. so people will have to get there house in...

thanks for the info andrew so i guess that each room will have 2 zones. 1 zone for contacts and 1 zone for ir sensors so they can be isolated. its becoming a little clearer now :) do you know of any alarm related websites cheers matt
