    Advise for a final year apprentice.

    If in your years of experience you could pass one bit of advise to a final year apprentice about to qualify what would it be and why? Is there anything you wish someone a little older and wiser had told you before you finished your time?

    Ring Final Circuit

    I have a query about the Standard A1 Ring Circuit. It is my understanding that a 2.5mm2 cable is sufficient, this is because the current carrying capacity in a worse case scenario is 20A and because they are run in parallel this gives a total current carrying capacity of 40A and so a 32A MCB...
