NICEIC assessment

[kung]

If you cant beat em ! as the old saying goes !

Had NICEIC assessment today and passed with Clive collett. Very nice guy ! helpfull and knowledgable etc as said in past post while i put in an extra socket at me mums had Ze of 6.2ohms ! dont ask ! some clown done a right bodge on a CU upgrade 5yrs back and no tests or certs included in price etc etc phoned mate at SSE and within an hr had a nice PME with Ze of 0.13ohm ! i have heard not as bad as thought it wouldnt be hard if you know how to test/inspect/install and know how/where to find answers you will pass if not learn first ! PM me and i will tell you what questions he asked/tests etc etc
Regards

No need for PM's

We want to know the questions AND YOUR answers

And ill put this thread in the right place shall i?

1) What would you do if the Ze was high ? told him about the 6.2 etc and got browny points !
2) Why do we do R1 + R2 test ?
3) What is the min IR value from bs7671 ?
4) Max Zs on 30ma RCD (p49-50) (table 41.5)
5) What are the zones in bathroom ?
6) Are you happy with your test results and why ? show me in regs where ?
7) I f you had a TT rod and got on loop test 69ohms would you be happy with it ? if so why ? 200ohm or less anything above would be unstable !
8) Whats max Ze for TNCS/TNS/TT ? show me where in regs ?
9) on 30ma RCD test whats max opperating time on x1 ? thats 30ma test current within 200ms ! and on x5 ? equates to 150ma test current should opperate within 40ms !

as V = R X I volts = resistance x impedance so R = V / I & I = V / R ! = Ohms law ! also V X I = P or W (power or watts )

= for those of you in black and white the cue ball is just behind the blue ball !


Some questions he asked

with my KT61 on PFC test had to do loop on PFC & PSSC and calc KA = PFC gave 0.16ohms so 243 / 0.16 = 1518.75 Amps / 1000 = 1.52 KA ! & PSSC gave 0.18ohms so 243v / 0.18 ohms = 1350 Amps / 1000 = 1.35 KA so PFC is 1.52 KA !
ETC ETC

Hey all
Anyone with NIC how long was it before you got your welcome letter with your reg/membership number in ?

Well done mate!

Not as bad as you think

Paperwork should be with you in a few days i would think.

Depends on how soon he sends the info back to H.O.

Also forgot to mention i have an old loop in loop out cutout system so told Clive as nextdoor is a childminder i couldnt just tell her and expect her to keep sprogs away from taps/metalwork etc and at home i couldnt do IR test only on single disconnected circuit as i did with cooker circuit but she was out when i did the IR on board as a whole eg L/N + E.
