Hi all, I'm brand new to the forum. I'm a DIY'er on my third house renovation (over the last 20 years). Having consulted a professional electrician, I know I need to run a new 10mm earth to the water meter. I happen to have a brand new, sealed, 50m roll of it from a previous project. BUT, it's 15 years old and been stored in a shed. Should I use it or fork out for some new stuff? I can't find any guidance online for totally unused, but old, cable. Thanks!
