a 6A, type C circuit breaker should do it, without tripping when the light is first turned on. how many watts does the new light use??

how long is the cable run? what do you currently use, and expect to use in the future?

rob nelson, you're gona have to make a lot of mess to your kitchen if you want to switch this from where your existing light switch is. your other alternative could be to put in a switched FCU between base and wall cabinets, supplied by the ring. if you wanted to then turn these lights on...

thanks for the replies i will go ahead, with this. thanks plugwash for similar thinking. ps as far as i can gather, 4mm ring was used because of wool-fibre insulation under the floor..

if it helps: http://www.diynot.com/forums/viewtopic.php?t=26936 use both as earths (ie get 3core SWA), for the reasons in the above post. part of the gland will include an earth connector, take this either to CU, or your earthing terminal. what did you mean by TS??

its what id prefer to do. however when suggested, they were put off by the extra cost (changing all kitchen sockets to match). but i don't know if there's a reasonable alternative.. thanks for your GET advice. not sure what manufacturer they currently have...

hi guys i have been asked to add on an fcu via spur to a ring as usual. however when inspecting, i have seen that this ring has been wired in 4mm2 cable, and consequently there is not much room in the socket terminations to add on another set of 4mm conductors (not even 2.5mm. ps this is...

i dont understand why any double sockets have not yet been designed + approved for use at 26A. to the end user, a plug is a plug, and they would not think twice about connecting 2 appliances on the same double socket. circuits are protected in the CU, and appliances by the fuse in the plug...

you're both correct, i shouldn't commit without actually inspecting. however my reason for being so sure is ive had (what appears to be anyway) the exact same cutout fit for that upstairs flat that i mentioned in another post. i watched siemens install the meter. if the fuse is removed, a screw...

@pj57 can you clarify whether this cable run and conduit is being run outside the house??

@adam haven't read any report. but thanks for confirming that they are only rated 13A. i didn't know if jaymack had found a new product or something..

the rating of the socket is normally on the back of it. i have only ever seen 13A total, but maybe there are some out there rated at 19A.

this is definitely a PME supply.

i would imagine both machines have a 13A fuse each?? there is a possibility (however unlikely) that you could end up using both at the same time. therefore ideally you shouldn't get one double socket installed for use of both (the socket will only 'cope' with 13A total). get two separate single...

@hdrw yes, sorry for not being clear. the layout is such that the shortest route between METs is obstructed by the old upstairs supply. unfortunately ban-all-sheds is correct, and the cable has been sweated onto the sheath. i can't replace it. for now im going to leave things as they...

@plugwash the TNS has been there for 40years at least, before PME even started. i can't use both in it's present state, as potentially the full neutral current could flow through the parallel path to the sheath, and the cable is undersized. i definitely would not connect the 2 earths...

thanks to all for your replies. i have spent a couple of minutes making this neat little diagram to show whats happening: http://i7.photobucket.com/albums/y278/user56565/earthing.jpg there is an earth link between the METs, also run in 4mm however i will be replacing this with 16mm once the...

can you supply a bigger picture with more detail.... as far as im aware, cheap electricity is normally 1am-8am. the meters i have dealt with normally have 2 readings, one that says 'normal' and another 'low'. there is an LED lit next to the one that is currently in operation. unless you...

@adam151 Thanks for your reply. Parallel paths are inherent when PME is in use even in a single property + installation, example main bonding to earth via gas/water services. These also provide paths for neutral currents to flow and are relied upon if the combined PEN were to be broken. In...

hi. This may look quite long but im sure theres an easy solution to this. There are 2 flats, one above the other in a detached property. The main supply came into a cutout in the downstairs flat, and from here, it was split into 2 sets of cables, one set for each flat. Earthing was provided...
