Hi all.

There seems to be very little information on past papers for the 2396 design course being run by City & Guilds.
6 of us sat the exam last night and i thought i may share a little of what i remember from the paper........the memory is not what it used to be.
Questions: In no particular order
1
A) Asks for the table numbers for grouping, ambient temperature etc
B) Installation of 36x 150w High Bay discharge lights split over 3 phases. Work out the Design Current, Cable Size, Protective Device, Volt Drop etc.

2 (I think) Small retail unit on a farm. TT installation with 20 ohms Ze and 2.10 KA. Calculate earth fault and short circuit when installing 4.00mm t&e, 30ma rcbo for a length of 17M
3 explain the effects regarding the proximity of services:
I Electrical
II Communication
III Other Services
4 TT installation Using 100ma RCD. State test measurements and likely results.
5 Explain why not to carry out RCD test before any other test is carried out.
6 Explain why greater risks to electrical installations in bathrooms.
7 List 10 risks with electrical installations in caravan parks.
8 i) Explain where switching for mechanical maintenance should be located on a conveyor belt with 10 operatives (230V motor)
ii) Select a suitable emergency switch and give reasons why.
9 Give details of safe and efficient earthing system for a portable generator in a marquee.
10 Provision for ADS in the marquee
11 List 3 types of notices to be found in electrical installations.
12 List items to be found on a circuit chart for a distribution board

Thats all i remember for now. There is of course a lot more which seems to have been erased from the memory.
Hate to say it , i think it will be a small miracle if I pass. The 5 others were no better off by the sounds of it. I would advise taking a separate course on speed writing to get everything down in the 3 hours appointed. Regards. Steve.
