For protection against shock, at least, I thought that this wasn't always required, based on 414.4.5. Is there another reason that they might need enclosing, hidden away in the depths of the regs somewhere?Even ELV should be contained and is a non compliance.
Fair point which goes against my thinking of Regulation 526.5For protection against shock, at least, I thought that this wasn't always required, based on 414.4.5. Is there another reason that they might need enclosing, hidden away in the depths of the regs somewhere?
Basic protection is generally unnecessary in normal dry conditions for:
(i)SELV circuits where the nominal voltage does not exceed 25 V AC or 60 V DC
(ii)PELV circuits where the nominal voltage does not exceed 25 V AC or 60 V DC and exposed-conductive-
parts and/or the live parts are connected by a protective conductor to the main earthing terminal.
In all other cases, basic protection is not required if the nominal voltage of the SELV or PELV system does not
exceed 12 V AC or 30 V DC.
thank you
This question actually came up on my niceic interrogation session.For protection against shock, at least, I thought that this wasn't always required, based on 414.4.5. Is there another reason that they might need enclosing, hidden away in the depths of the regs somewhere?
