oh but if there was space on the RCD side of the exisitng board i take it i can just move that circuit over to there?

so an easy senario would be i go in and install downlights in the kitchen i will now have to comply with hte 17th regs and protect that circuit with an RCBO if the consumer unit is say a full board and no room for movement. the rest of the board (apart from earthing and bonding) is not of...

the water heater would be on all the time so when the hot tap is turned on it comes through hot. it wont be used as an on off switch as such. more like switched on left on so how come its in there regarding 30cm away? is that not right then?

thanks mate that helps me out to continue with this ..... from july 1st if i went into a property to change a circuit do i now have to RCBO that circuit? or do i have to say your CCU now needs upgrading or do i just note on the certificate that it doesnt comply with current regs? Plus...

sorry i only read half your reply, thats where i kind if disagree with one of the regs, in a kitchen a socket can be only 30cm away meaning you can use it with wet hands very easily so if thats ok this must be ok

ok so that gives me the scope of common sense and not specific regs like locations containing baths or showers. So a very small sink used to wash face and hands would be ok with a 13Amp fuse spur just to the left of it. afterall much bigger sinks in kithens can have them only 30cm away

Hello guys I just wanted to run this past you i am aware of the 17th regs regarding domestic where all unprotected buried cables less than 50mm etc have to RCD protected but how does this relate to commercial for example a building that has had drops of switch lines in plastic oval...

Hello Im all up to speed with the regs regarding special locations containing baths and showers with distances and IP ratings etc but i just wanted to ask this.......... I am presently working on a holiday home that has a sink in each bedroom, now above each sink is a 13amp switched fused...

thank you for the info much appreciated

many thanks mate for your time on this issue :-)

as always thanks spark123 :-)

Hey spark123 just to inform you ive just chatted with him and he gained some advice over the phone. he did the ramp test and the rcd was tripping at 23mA so all cool there so he then did the same no trip test by using the martindale plug with the back three holes exposed and used his...

Hey spark thanks very much for the info, great help as always :-)

does maintained mean the light is used as part of the normal lighting circuit switched on and off with the lights but when the circuit fails the light stays on via the battery charging from the permanent live then non maintained means the light only comes on when theres a break in the normal...

so if he carries out the ramp test and the rcd trips before 15mA then the rcd is faulty what kind of current does the Zs test put through a circuit? Plus is there anything the ring final circuit could have wrong with it etc?

unfortunately that part is beyond my knowledge at the moment, i know that its a block of flats he is testing so its a general 30mA rcd i know he ran the test on the rcd ans it was fine out of interest how much current does a circuit take when Zs tested? i take it the ramp test will prove...

unfortunately i do not know the exact details of the rcd, he did all the relevant tests for the rcd ans it was fine and also did no trip zs tests on other circuits and it didnt trip so it must be something to do with the ring im guessing?

Yeah when i spoke to him on the phone he said everythin was unplugged. what are the list/range of possibilities that can trip the RCD on a non trip and i will run through them with him next time? Many thanks mate

Hello I work on occasions with an old school spark who doesnt use a PC much so i said i will ask the expert brains on here regarding this issue Upon doing a Zs test on the ring final using the usual plug on lead from the MFT1552 tester, He applied the non trip Zs due to the ring final...

hello guys Many thanks for your info my circuit now looks like this 3 x halogens on indivdual built in PIRs. 1x 70W son on a timer all protected by a 10A type C MCB cheers
