Here is a questionnaire I got handed from a sparky I know. I have no idea where he got it but interesting to see how much everyone differs, I know I did!
------------
You attend at a house partially constructed, the previous electrician left and it is now over to you to finish the work.
Upon inspection of the existing work all looks in order but you have a few potential problems. It is undertaken to the 16th regulations and during your inspection you find:
(please answer what you would do, if anything)
1. The kitchen has a split hob and oven, the hob is gas and requires a spark supply, what would you use to power this, it sits alone at a good 8 feet from the oven and it is not possible to connect to the oven supply, it is surrounded with sockets on a kitchen and utility ring main. RCD protected at the board and on a 32a MCB. Where would you supply this from and what fittings would you use.
2. During your inspection you have a look at the oven to see how possible it is to wire the hob from here, upon opening the 20a double pole isolation switch to the oven you find it is only 2.5 mm twin and earth. This comes from a 16a MCB in the DB. The client states the ovens power is only 2.5kW in your opinion would this be acceptable?
3. Presuming you are satisfied with the supply at question 2 you go to look at the oven and find the your client is incorrect. It is actually a 4.6kW double oven. Would this supply still be suitable?
4. Also in the kitchen, you discover a 1 gang socket under the sink, this is to power a dish washer sat next to the sink. The socket is within the sink cupboard and forms part of the RCD ring mains from a 32a MCB, would you be happy with this.
5. Whilst inspecting the DB, you find that the supply to the garage is from a 16a MCB and is RCD protected. The cable supplying this is 2.5mm Twin and Earth. The cable run is 30 feet. Within the garage is a small 2 way DB with a further RCD protection. This is supplying 1 x socket outlet, 1 x light fitting and 2 x 300w garage door motors. Would you be happy to leave this as it stands?
