i thought you could no longer plug an oven into the ring main,even under 3kw,or have i misread something?

thanks for the replys. system is ok, no rubber.lighting earthed,pipes bonded, securespark, do you mean a seperate rcd for the sockets and another for the cooker,or a rcd with two mcb's,and do away with the 2 mcb's in the main cu?or could it be done with a main switch unit with 2 rcbos?

what would be the best way to add rcd protection for a cooker cable to be moved and reburied {not in the kitchen} and a few sockets added in bedrooms,, the consumer is an old wylex with just mcb's and a main switch, i don't think that you can get rcbos for them.

same to neutral, they hav'nt been connected yet,wanted to find what could be the problem, out of interest, what's the reason it is showing 140v thank you both.

i was putting a couple of wall light fittings up.and was testing for voltage with a multimeter,on both lights it was showing 143v between live and earth,also 3 or 4v on the earth and neutral,what would cause such a low volt reading,there are no other problems,and the lights work ok.

thanks for the replys,taylor would the switchfuse be 100 amp same as the main fuse?what size armoured would have to be used. i have told them to contact their supplier.

a mate of a mate has just moved into a 40 year old house,and he knows my interest in electrics,he asked me to help him find the consumer unit as he couldn't. it was'nt that hard,it had an outside meter on the kitchen extension,but the cu wasn't directly on the inside wall,a washer was...

lost me,just wanted to know how to connect cooker and hob to existing 6mm cable,as i understand it the 6mm is rated around 46 amps as long as it dos'nt go through insulation and no volt drop. could the 30 amp fuse be changed to 40 amp?

thanks luminaire, sorry rf don't understand,

what's the easiest way to connect a 6kw hob and a 2kw oven,to an existing 6mm fed cooker outlet.thanks

thanks spark,that's ok if you are doing a rewire and you can design it from scratch,what i was asking is how you sparks are coping putting these regs in existing installations. where you have the old wylex boxes,or split load cu's, can you also answer the question about battery backed...

thanks all,so if the alarm has a battery back up,can it be put on one of the socket rcd's,as the alarm would still be working even if the rcd tripped? and would you have to tell a customer that they would have to fork out for a second cu just to have a couple of smoke alarms fitted. sorry for...

thanks for the reply,i would assume no one would want cables surface mounted up and down their walls. i read various forums and most popular cu seems to be just the double rcd type.so are sparks just putting the smoke/burglar alarms on let's say the rcd with upstairs sockets, just trying to...

been reading threads about smoke/burglar alarms,but still a bit puzzled. if you fit the new type of consumer unit with a main switch and two rcd's,how would a smoke/burglar alarms connect to it,as i understand it the alarms have not to be on the same rcd as sockets,but would'nt there be a ring...

it's a 5mtr extension lead, i will check the continuity of the cpc on the lead and the circuit, thanks

thanks for the replys, rflighting,i don't have a rcd tester,but i could probably borrow one,what would i be looking for?and if it's the rcd or the cables.why does the washer work on another socket on the same circuit? taylor,yes the kitchen is the only circuit on the rcd,all the sockets go...

a kitchen has been run in a 6mm radial(no idea why 6mm) one side of the kitchen is the old red/black cable,the other is the newer brown/blue. it looks like the kitchen is only a few years old and new sockets have been added to one side of the kitchen into the radial circuit,the rcd is a...

sorry taylor,but i hav'nt disputed any of the advice,my last question was about jaymack stating that under the 17th, 2kw would be the maximum,which i assume would exclude all ovens being plugged in. i appreciate all the advice put forward.

so with the new 17th regulations,no cooker can be plugged in.

thanks everybody,just thought might get away with it. jaymack,are you saying that no device over 2kw can be plugged in,or just cookers,and why?
