NVQ Lvl 3 Written Questions! (I need a hand)

[kiwiNCFC]

I am doing some of my unit work and there are a few questions I am stuck on.

Unit 306 (Install Wiring Systems)

1) Describe what procedure you would follow to ensure the electrical supply was suitable for your purpose?

Would I be right in saying that this is asking about the supply type? i.e tt/tncs/tns & what does it mean by procedure?

2)Describe how the costs are recovered for additional works carried out by your company?

I don't really understand this. In our little 2 man band if the customer asks for additional work we just add it to the bill. Is this what they are asking for?

Thanks in advance!

Would I be right in saying that this is asking about the supply type? i.e tt/tncs/tns & what does it mean by procedure? and will it carry the load safely?

2)Describe how the costs are recovered for additional works carried out by your company?
