when you sell a house it is perfectly normal to have to sign a legal declaration prepared by the solicitors saying something like "has there been any building or electrical work done on the property in the last 5 (for example) years? if so supply details below...." if you say yes the...

and then there is the violation of notifying the work according to part p of the building regs. I strongly advise you to leave the work well alone.

with a push to break the light will come on if the door is ajar, i think he only wants it on when the door is fully open as he said in the original post "The moment the door is slid back to be closed, the light to switch OFF". I agree with your other points.

you guess correctly, think of the capacitors as small rechargeable batteries, it helps that clock circuits and LEDs dont use much power. to keep the PC running you would need a ridiculously sized capacitor, a lead acid battery is smaller for the amount of charge held which is what is used in a...

I believe it use to be 240V +-6% then when we moved down to 230V and mainland Europe moved up it became 230V +10% -6% for us (and i think 230V +6% -10% for them) . i believe at present the average voltage in the uk is 238V. edit 1: (i didnt check the values but Im sure if there not right...

what about SP RCBO's? i thought they were the future? i know the point has been discussed before but Ive not seen the conclusion.

^shouldnt the switch be rated equal or higher than that of the protective device of the circuit. And the protective device should itself should be higher than the anticipated load as you describe, but lower than the cables maximum (given the length and installation methods of the cable not the...

when in france years back the caravan we were in gave a distinct tingle when you had one foot on the step and one on the ground outside, we reported it straight away (was Haven or Eurocamp or something similar), i dont recall them sorting the situation whilst we were there. We found having the...

The focus on the article seems to be that the plumber did not spot and sort out 'faults' on the electrical system and that he shouldnt be touching the electrics now the new regulations are out as he isnt 'qualified'. Well before part P he still wasnt qualified and all of the 'faults'...

can the OP confirm that it is just the cooker, and clarify that this is the oven and electric hobs, or if it is the oven and gas hobs etc (also turn it off and see if anything else goes off) and then tell us the rating (kW) of the cooker (and anything else found to be on the circuit). The rating...

what is the 45A breaker which is already in there feeding? and what is the load (kw's) of this?

no! you bond metal objects that may bring potentials into an area, to ensure they all remain at the same potential. A bath alone can not bring a deadly potential into a bathroom, its the pipes you are concerned with (and CPCs of circuits etc).

sounds like it had an N-E fault (or possibly some other fault), on a typical 16th board the situation would still be the same as plugged in appliances would be on the same RCD, but i guess you are saying that at least you wont get nuisance tripping on the other circuits (at different times with...

the 17th came in at the beginning of the year (feb?) the 16th went out at the end of june. I cant understand why people go to measures to 'ensure that' they can wire to the 16th. i understand when moving a lightswitch wired to an old fusebox but if your doing significant work why pay all that...

heres a thought, could the light you are working on be on an FCU (fused connection unit) the work you have done may had blown this fuse rather than tripping anything in the CU? just a stab in the dark, all I can do without been there!

its not the age of the property its the age of the electrical work been done. If you add new sockets you must first make sure that earth, over current RCD etc stuff are all present and correct and work is done in accordance with current wiring and building regs. not sure about like for like...

^read it again SS is right in what he said.

It will use less, but not proportionally. Incandescent lights are more efficient the more current they have, this is most noticeable when they are run at/near/over their maximum. So if you reduce the current a bit you loose a lot of light. So for example (made up numbers) if you give the light...

no I am another one that thinks you are wrong and that you have probably misunderstood what consultants, cibse and bsria have been doing with bits of yellow and green wire. Anyway I have said my bit I will sit back too many cooks spoil the broth and all that.

Probably? I how about definitely! and you definitely wouldn't bond it either! grasping the reasons for bonding can be a pain, especially when you already have preconceptions as to why it is there and why everybody else has been doing it, but really holmslaw you need to forget everything you...
