Hello Benny, I am checking out the cable distributors thoughts on their particular brands and apparently they conform to a European standard and despite not being copper in total (the cores are aluminium with a copper coating) they reach the standard of 10 ohms at 100 metres, which is more than adequate for a domestic property..so, no worries on branded there. I should imagine that you would be paying a great deal more for solid copper (keeping the costs down)but it's your choice at the end of the day.

Hello Benny, "..thats not correct there is a bs std now for cable, en does not have a cable std.." whatever, just go with the information from the manufacturers as mentioned previously..it's no big deal as long as you have 10ohms @ 100mtrs the rest may be viewed by most people as 'nit picking'... but it's up to you.

CCA cable is harder to work with, as it often has a cheaper and less flexible outer jacket, often poor quality, and prone to being fragile at terminations as aluminium is.

 

OP, do yourself a favour and spend a couple more pounds - that's all it is - on quality, copper cable. You won't regret it!

So, I've decided to take my work back underground.... to stop it falling into the wrong hands
