ELECSA Certification Scheme Elecsa assessment soon questions about EIC for job

[Deleted member 26818]

Could he then use both the house and the shed as two separate jobs for assessment?

I think the answer to this is yes, as they are 2 seperate Jobs

 

[telectrix]

yep. that'll save a bit of diesel/petrol.

Change the CU and use this as your assessement,if it is your first which I think it is, concentrate only on the CU change in your house.(You only need one job on 1st well I did unless it has changed)

The assessor is not there to test your design skills but to make sure you are SAFE and COMPETENT to carry out electrical work.

He or She will ask you to demonstate basic testing procedure ie PFC ZE or RCD trip times or even continuity of protective bonding conductors along with asking questions re knowledge of the BRB.(Basic)

They will look at you EIC & both schedules to make sure you are testing correctley and recording correctley.

You will find that the assessor is only human and they were in the same position at some time in their carreer and will know that you are apprehensive and uneasy.


The info from the forum members is spot on and that what this forum is all about.(IMO).



Good luck and post how you get on.

hi
surely the shed feed would still need rcd protection from the board as the cable is a normal pvc twin and earth conceled within the wall down a corner, it is less than 50mm can someone correct me if im wrong

cheers everyone for the help.

 

[malcolmsanford]

Your quite right if the T+E is subject to regulation 522.6.6 and therefore 522.6.7 then that cable will have to be RCD protected.

 

[lucus]

though as much so is there anyway of having rcd discrimination i did think about using a rcbo instead of the 20amp mcb in the house fuseboard, would this work? or would it just trip the main rcd aswel?
thanks for the help.

 

[Deleted member 26818]

Could be on or the other, or even both.

 

[telectrix]

if you are fitting rcd protection at the house end to protect the cable feeding the shed, then you don't need rcd in the shed.

 

[SimpleSimon]

Tels right, unless your cables in the shed are buried 50mm without any mechanical protection than we're guessing they are surface mounted, run in conduit or trunking therefore dont need RCD protection.
However just another point, what are you doing for earthing? If your going to TT Im afraid your going to have to change the CU from a metal clad one to an all insulated one. If TNCS have you called DNO like Malcolm says?

Yes, here's the ESC advice on the consumer unit type:

NDQ14
Is an RCD main switch (such as a 100 mA time-delayed device) still required in the consumer unit of a new domestic installation forming part of a TT system?

​

NDA14
For a domestic installation complying with the 17th Edition where all the final circuits are RCD-protected, an RCD main switch is no longer required, provided that the consumer unit is of all insulated construction.

Is that stating that if u had an RCD s type 100mA main switch you can have a metAl clad CU?

 

[IQ Electrical]

Not a consumer unit main switch but if the rcd is between the supply and the consumer unit, disconnection is achieved on any fault on the supply side so why not?

Makes sense. I was just following regs
