Here are some of the questions I can remember from the 302 exam I sat just before christmas.

1. List where you test on a 3 phase and neutral installation to confirm Safe Isolation?

2. What documents are required for a new installation, who is responsible for determining next test and who the forms are given to?

3. Sketch layout of a TN-C-S domestic intake position? Page 15 in OSG

4. You are testing Earth Fault Loop Impedance on a TT system.
Why is it necessary to isolate the installation before testing?
What do you have to do with the earth conductor before testing?
Why can reading be recorded as the electrode value?

5. Ohm meter giving incorrect reading.
2 methods to verify?
What do you do if faulty?

6. Identify 3 factors which can affect the time taken to complete an installtion?

7. You are working onsite for a few weeks
Suitable storage for tools/equipment?
Precautions for materials onsite?

8. 3 methods to make area safe before starting work?

9. You had to draw a diagram for a an earth fault loop path for a TN-C-S system for a fault on a fixed load within the installation.

Struggling to remember how the rest of the questions were worded but here a few ideas from what I can remember.

There was a question on working out resistance in a parallel circuit.
You needed to work out metal conduit size using onsite guide.
There were a couple of questions on faults you may see on a consumer unit and a pendant.

Can't think of any more at this stage, but get in contact if you need anymore assistance.
