Panel/Switchgear Yellow Electricity Warning Labels

Former Community Member
Former Community Member
Guys,


I am trying to find the specific standard that states what voltage value is to be placed on the yellow colored electricity warning labels found on panels/switchgear. As I understand it the electricity warning sign template is coming from ISO 7010. However having read ISO 7010 I can see it makes no reference to what voltage value should appear on the warning label.


Is it the nominal voltage, is it peak voltage, is it rated operational voltage ? 


What standard is specifying this ?

    It would really clarify things if BS7671 514.10.1 used the term nominal instead of maximum.

    I suspect it's just trying to cover the (perhaps unusual) case where there's more than one nominal voltage present within the same enclosure - you'd just have to have the highest on the label, rather than list all of the ones that exceeded 230V from Earth individually. Perhaps it could say 'maximum nominal voltage' though.
