it wernt that bad mate

 

[mtfpuk2011]

which bit did find hard

 

[PeterPan27]

Anyone reckon or no if 60 to 65 percent be a pass?

Hour and half just wasn't enough time tbh.
I counted back in last minute and reckon I got bout 60 percent

 

[mtfpuk2011]

its a floating mark mate there is no fized mark.i found all ok bar for icn and ics rest was a good paper

 

[PeterPan27]

Well didnt have e ought time todo last 2 questions but tey only 2 marks each so may not be major..
When said explain how test the cpc I started off seek permission etc do safe isolation I just basically said place link on line and earth at cu then measure the r1 and r2 at each point recording highest as r1 plus r2. But when had to do the insulation resistance test I jut basically said the safe isolation has already been performed when doing the R1 R2 but if it hasn't I would go they whole safe isolation again.. I Sao would test as a whole between L - N L-E and E-N and althought bs7671 says on a 400/230 1m ohm is ok anything under 2 m ohm I would test the circuit individually..

I found the ics icn easy just the rest haha. Where is phase rotation test done on a heater ?

 

[mtfpuk2011]

I believe the phase rotation test is done at the isolation point. What is the ics icn though?

 

[terminator]

My translate doesn't seem to be working?

 

[iamelectric]

ICN- breaking capacity but may not be re-usable
ICS- serviceable breaking capacity

 

[PeterPan27]

Breaking current that will safely interrupt but may not be usable

Other
Breaking current that will safely interrupt without loss of performance

 

[mtfpuk2011]

ok I got that rong then but I think.i.did all right on the rewt

 

[PeterPan27]

Terminator my explanation that bad eh haha

 

[PeterPan27]

If that only thing you wrong you defo past.. I'm looking at aug re sit

 

[mtfpuk2011]

I found it ok to be fair but wate see time .im booking just in case but hope I have done it ad tryed 91 last year and that is a bitch of a ex
