Hello List Experts,
In the USA, once inside the electrical enclosure, we are generally
permitted to have uninsulated live electrical parts, if desired.
A review of Sec. 6.2.2 of EN 600204-1:2006, covering the general
requirements of electrical equipment of machines, seems to permit the same
construction, although I've been instructed in the past that at least an IP2X
protection is needed even inside the electrical enclosure. Note, for purposes
of this discussion, that it is expected that the servicer will disconnect power
to the product before opening the enclosure and that there are no residual
voltages after power is disconnected.
I would appreciate any advice concerning what is the expected minimum
level of protection for such 'live' parts inside electrical enclosures on CE
marked equipment.
Thanks in advance.
Good day,
