UL Classification Marks

Toolstation have a Rotary Isolator 4 Pole 25A 11kW 415W which they show as "EC947 UL approved".
I've been looking on the UL.com website, but so far haven't found a technical explanation - I assume it's a reincarnation of IP Code, with the US again taking over as World Lawmaker, again.

So what are you asking

EC is Euro
U.L looks like an equivalent of BSI, not an I.P rating.

It's an American approval, the UL stands for ''Underwriters Laboratories'' and has a similar standing as the BS kite mark has in the UK!! UL means nothing as far as UK/ European standards go unless the product also holds a EC number....

UL has absolutely nothing to do with IP ratings whatsoever!!

Thanks for the quick replies, engineer54 and snowhead.
I'll ask Toolstation for the IP rating.
