Maxxy, if you did not understand the question, why did you waste yours and everyone else's time adding drivel as your answer?

crafty1289, why is who I am relevant?

I asked the question because I do not know much about electricity and expected respondents in this forum to be more knowledgeable than myself, and give me a straight answer.

I asked the question because last week I bought 2 core + earth cable: it was of type a. I described in my original message. This week I bought 3 core + earth for wiring an extractor fan it is of type b. I described in my original message.

I wanted to know the guidelines or rules or standard practice for using one type or the other. I am certain there are rules for using one type or another. Simple enough?

b. each core has multiple thinner wires and the earth is insulated.

a is CABLE. This is used in permenant installations. Larger sizes have multiple strands in the cores.

b is FLEX. It is not called CABLE under any circumstances. It is used on appliance leads.

two core and earth CABLE is called twin and earth. often abbreviated to t+e. 3 core and earth CABLE is often abbreviated to 3c+e.

With flex, is isn't called x core and earth, since the earth is also insulated and is the same size as the other cores. You just say 3 core and 4 core.

I do not know much about electricity

Get plenty of advice before hand if you do do this yourself. Try searching this forum for other posts where people have installed extractor fans
