questions regarding my NVQ level 3

[davedwr1978]

hi
I was wondering if anyone could help regarding a few questions i have in my nvq please, i am struggling a little in wondering exactly what they are asking me to find, maybe someone could put it in simple form for me haha, the questions are;

provide written and if possible photo evidence for each job.

1. Verify compatibility of the electrical supply to the installation spec?
2. that planned installation are except able to the spec. ?
3. planned locations are compatible with other site services. ?

the jobs i am doing are

1. complete re wire of a kitchen.
2. complete rewire and refurbish of a plant room in a commercial residential home, all wiring and containment systems.

any advice would be appreciated, as i have completed the rest but i think i am going through some kind of block, and i wanted to complete it before i return to college in 2 weeks thanks guys.

I would say that 1. is asking you to provide confirmation of the supply voltage, frequency and maximum demand indicated in the installation specification match those of the installation into which you are planning to install. Measure voltage and frequency, check size of protective device in supply (if possible), derive from the specification the demand of the new installation and determine the demand of the existing installation and demonstrate that there is sufficient capacity.

It is possible that 2. is asking about maximum demand but the question is not clear, perhaps you could check the wording.

I would think that 3. is asking, for example, if the specification indicates a standard socket in shower cubicle, open unsealed electrical switching in a hazardous area, this sort of thing.
Are the accessories suitable for the location considering other services, does the electrical installation obstruct other service runs /equipment / access points or vice versa.

Only my ideas of the intent, but possibly useful.
