I am working on a legacy electrical design, where one of the actions from a recent design review queries the use of 3x 230v door mounted LED for indication of 3ph 400v to the panel's main incoming busbar.
My understanding is that this is not specifically prohibited in 60204-1 but is generally considered to be poor design practice and not as safe as practicable, where I would expect this to be flagged at a design review. Also there is no requirement for this in the end-users site specification. As far as I can see, 60204-1 has specific requirements for touch safety, bonding, wiring and uses of door mounted devices, but it does not specifically state that LV on panel door-mounted equipment is not permitted. Similar issues arise with the use of 230v vent fans on doors etc.
I am expecting that the design will be amended with an ELV alternative, however I wanted to query the regulations for the client.
