JohnD if u are fully conversant with BS 7671:2008 enlighten me with the answers to my questions 8), if not continue to correct people and somebody will hire u ------------------------- "You can't arrest me, I'm a Rockstar" -------------------------------------------- "It is much more...

Anyone know if is correct current discrimination between Type C 32Amps and downstream BS 88 (fuse) 32 Amps :?: Good weekend fellas 8)

Hi fellas Circuit should be taked as two parts, one test for radial-record results,second test the ring-record results.For recording the values in schedule of test results record 1st radial(0.11) ohms, and for ring somebody sugest me that should be recorded the highest value for ring(wich was...

OK fellas, lets forget CCU and CU, any electrician express himself in his way, give remarks at that circuit, this is the main question... Cheers 8)

Holmslaw u right,this circuit could be taked as two circuits,or could be treated as radial at whole, if u make a note on schedule of test results about it 8) , in special that I had readings as follow: for p-p loop 1.0 ohms, n-n 1.0 ohms, cpc-cps 1.0 ohms, and from 5 socket outlets just one had...

CCU - Consumer's Control Unit :) I'm very puzzled when you say "3 phase+n isolator BS 88 fuse 32Amps, thru 3x4mm single core conductors(phase,neutral,earth)..." 3 phases but only got P+N+E? Think that u have one CCU in one side and one 3P isolator in another side, from CCU u have 3...

No replicas boys :?: , is all about experience :D I wait for it... 8)

The CCU is TP+N,main switch is 100Amps BS 60947, untill here everything is ok :D ,on CCU u have 4 circuits,one of them is the 32 Amps type B MCB which feed a 3 phase+n isolator BS 88 fuse 32Amps, thru 3x4mm single core conductors,(phase,neutral,earth),enclosed in PVC trunking, where the phase is...

So :D , you have on CCU 32 Amps type B MCB which feed a 3 phase+n isolator BS 88 fuse 32Amps, thru 3x4mm single core conductors(phase,neutral,earth)... From isolator is connected a ring final circuit thru 2.5mm conductors You must test this circuit and complet the test of schedule results...

How other mates wrote u before, many modern meters check for voltage and will not allow to test if earth is not present. I ve got MFT 1553 and I ve done home EFLI correctly and after without earth(with earth leed connected to some metal wich is not earted ex. bath tub wast), the meter will show...

The results were for 5 socket outlets between R1-Rn and R1-R2, where the values between R1-Rn and R1-R2 was approximatly almost the same... Thank u

I ve got, end to end for R1,Rn,R2 which is P-P is R1 loop,N-N is Rn loop, CPC-CPC is R2 loop,after, R1-N2, R2-N1 measure at sockets outlets-record values, after R1-CPC2, R2-CPC1 measure at sockets outlets-record values, I think the highest values were because of resistance what they have mounted...

P-P 00.7 ohm N-N 0.07 ohm CPC-CPC 0.07 ohm 8)

I ve asked u about R1+R2, or R2 measure because in my two light circuits test rig I had the mettalic trunking as cpc, so I get just R2 value and record it, R1+R2 was t possible because of innacurate value due to mettalic trunking. And sorry I think I miss some I had 2 isolators, both of them...

Yes 30 A BS 3036, :?: what do you thing about breaker type B 40 Amps to feed subpanel,and main isolator in subpanel was RCD 63 Amps,I think for RCD in subpanel was accepted armoured strand of swa as earth,normal in any installation a suplementary earthing conductor (at least 10 mm for 10 mm...
