you need to apply for a competent persons scheme i.e Napit or Niceic etc, you say you are fully qualified so joining one should not be a problem.

i will check the things you suggest Prodave, thanks for the information, hopefully will do it soon.

problem i come across quite a lot is that a switched fused spur is fitted above the work top and then they fit a single socket under the unit, so they can plug the appliance in, the problem then being they have 2 x 13 amps fuses in the circuit and no fuse discrimination.

Hi All, I wonder if some one could help me, i have a Samsung 32 inch lcd tv, i have no picture but do get the sound, i have tried replacing the Capacitors ( one was bulging at the top) but it still has the same problem, i tried ringing Samsung ,but they just passed me onto there recognised...

you seem to worrying about breaking capacity of the fuses, when you will get no where near the fault current that will damage them. The fault current you measure is important so you can compare the result to the ones in the time/graph characteristics in the regs book, i.e 160 amps minimum for a...

if you are a Napit Member you could always ring there Legal team for advice

you should really get the information from the manufacturers and you also have to work out the space heating for each room, are you MCS registered or is the Builder

thanks steve, we eventually got to the main question

I did a test and inspection on a domestic premises and noticed the RCBO's installed were type C, these have a much lower Zs value than the type B, apart from that i always assumed type C's were for circuits with equipement that had a high start up current. Are type C RCBO's acceptable in...

Hi All , That was my point from the begining, i always dis-connect the CPC from the earth bar at the consumer unit and connect to the phase conductor,its the only way to be sure of continuity and ignoring parallel earth paths, Thats why i disagree with the procedure in guidance note 3 for...

Surely dis-connecting the supplementary bonding for checking the correct measurement of the lighting CPC (R1 R2) or Zs is no different to dis-connecting the Main Earth and removing any parallel earth paths ,when carrying out a Ze test ( with the consumer unit switched off).this is done under...

Hi Andy, All i was trying to say was that when completing a test report you are testing the cpc of a circuit for R1 R2 and Zs with supplementary bonding in the bathroom you may assume you are ,but in effect testing the supplementary bonding. It maybe that when testing you might not know that...

you have to be carefull as the person responsible for the PV install has to have all installation certs available for commissioning paperwork otherwise it doesnt conform to MCS requirements.

Hi I am testing a property at the moment and have considered what i feel is a bit of an issue, also if a fault developed at the bathroom light fitting, with supplementary bonding in place would'nt the fault current be more liable to take the easier path to earth and go the pipework instead of...

when testing ZS at a bathroom light fitting ( last light in circuit) and a supplementary earth has been connected from the pipe work in 4mm, surely this would give a false Zs reading. Also when carrying out continuity test for the same circuit, guidance note 3 shows placing a link between the...
