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.

Suspect confusion of EN with CE marking. Any old tat easily attains a CE mark, especially when self certified funny enough...

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

 

Thanks. And thanks for the quick replies. Gives me a lot of things to mull over.

Now I just need to look at placement of pirs on my place. Every bloody corner looks out onto a window or a rad or is somewhere near a rad lol!

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!
