Hi Am running one swa cable 6mm ( mcb at house end cu is 40a )and using a cu in the outhouse as a distribution box with mcb's 16 a for power and 6a for lighting a bit OTT but think is ok. Already have the cu's so cost not an issue Putting the rccd on the house end will protect the cable...

Thanks guys It won't take out everything as the rccb in outhouse cu situated in the house should blow first intend to fit. 63 amp unit. Cover provided by the emergency lighting. Should therefore be fine I think. Cheers

Thanks guys Think I will fit a non time delay unit in the cu for the outhouse situated in the house and leave the cu in the outhouse (distribution box) with just a disconnector switch and the MCB' s . No worries on the lighting front as installing emergency lighting over the bench just in...

Thanks for that. Yes we do run on an earth rod (Very rural) Why would you also need an rccb in the out house as well. Surely protection is provided by the rccb unit in the small cu at the house. The cu in the out house is really just a distribution box using mcb,s Sorry if sound a bit thick

Hello Have bought a small consumer unit to power an out house. Unit will be sited in the house next to the main board. Will replace the double pole disconnector Switch with an RCCB for safety. Can you please tell me the difference between a time delay RCCB and a non time delay. Board is...

I have a large house with two CU units about 5 years old professional intallation. The lighting one has a red 100a Switch disconnector (apart from lighting in contains a 20a RCBO for the Front gates and pond and a 45a RCBO for the shower). The other used for power etc has a 100a rccb. Is there a...

Much obliged to all who helped me Over and out Cheers Andy

Said in jest . Built my own house and everything is certificated and correct. I do not break the rules just question them sometimes. Even got a cert from Thames water because my bath is larger than normal. The reason I went on the forum was to ensure I got good advice about the rules. I said...

Role on wi-fi electricity !!

As you say it is about knowing it is there Our outside power supply - 4 massive wires with no earth enough to run a large hotel come up through a wall in the lounge the other side of which is the boot room with all the meters ect. I stuck a a bloody sign behind the mirror on that wall to...

well it has certainly dived opinion

my priority is our safety and not meeting the needs of the wealth and safety dept who seem to tie themselves in knots. Most inspectors (and it will be inspected) take the same view i.e. is it fit for purpose and totaly safe which is good enopugh for me. Not trying to bend the rules just...

Seems to me twin and earth in metal conduit is acceptable. Due to the wording it would stand up in court. Also does not say it has to be burried

Said that tongue in cheek. Will use good quality metal Cheers

Looks like I am ok and it does not specify plastic or metal conduit. Many thanks to all

Below the gravel is solid concrete. No chance of any work in that area could lay warning tape on top. "There are no problems only solutions" Cheers Andy

Thanks guys From the back of a socket but could change that Good earth in shed but need to earth the conduit. Nice little CU in shed with circuit for the light and one for the two sockets

about 40 feet - i only ask because that is what is there already. Nice tidy job shame to rip it out. realy tough conduit has been used with threaded joints.

Will talk to the buiding inspector and see if he will grant a dispensation for running the swa in the gravel splash strip next to the house. when I buildt the extension he gave me permsiion to use Wi FI smoke and co2 alarms with a remote alarm in the main bedroom than hard wired ones...

Is it accetable to run from a spur to a shed using 2.5 T and E cable in steel conduit securely clipped to concrete posts and concrete boards. Assume an earth clamp to the conduit to a sutiable earth point is required. Cheers
