hahahaha....i had to read it twice to undserstand it. his mother likes alan as well as easter....

Never to late mate. You'll do just fine, especially if you like the theory behind it. I started and and finished my college a few years back with no site experience at all. I used to be a qualified chef for 16y prior to that.

I don't think are such things. You only can get two prep days at college for the AM2

My first job on my own....I like to make sure I do everything by the book, don' like to bodge things and hope for the best later. 

Sorry mate, been a long day......hehe hehe I was worring for nothing.... I just answer the question myself....in case of a fault/ overload the MCB will turn the circuit off....

Hey Andy. I am on my last leg of the NVQ ( aprenticeship) mate. (An RCD only disconnects the supply in the event of an earth leakage.) I  need some advice . because the cable is protected by a 40 A MCBO at the origin of the installation

Hello everyone. I need some advice. I am wiring a shed (more like a room then a shed). I am wiring it in 6mm swa clipEd direct outdoor.  The distance between the C.U is approx. 30m. I am protecting the cable with a 40A , 30ms disconection RCBO in the C.U. At the other end of the cable, the...

It worked fine....

Hello mate I will PM you my details

...as reasonably practicable...lol

Thanx Narator. I think this post deserve to be pinned, as is so important.....

hahaha, is this the assignment for 305?. I am sure that you can come up with at least a couple of examples for each cable. Think logicaly of each external influence...

I will have a go at it....I started this topic to learn some things, after all The PEFC is determined by the low resistance of earth and the parallel path to earth of the consumer side ( I am thinking of bonding connection as the test is taken with the installation energised and earthing and...

Thanx everyone for your answers. yes, sorry, for domestic installations is less probable for the PFC value to exceed  6kA. apart from big cities where fault current (Ipf) might be higher. Also earthing system and location of the installation, determines the value of PFC.

thanx for sorting it out. all fine now
