Can anyone clarify exactly what changed in CU's for 17th edition?
There seem to be for sale CU's that are marked as '17th edition' and those from the same manufacturer that *seem* to have identical features but are not (older stock or something more?)
What would be wrong with a modern Wylex split load box with both sides protected by RCB's that's not marked 17thEd?
