Current standards require the the main lugs before the service disconnect be protected.

Is that a FL thing Dave? I can’t recall ever seeing lugs covered like that on new homes, around here anyway.

It has been in the NEC for several code cycles. This is from the 2020 NEC:

230.62(C) Barriers.
Barriers shall be placed in service equipment such that no uninsulated, ungrounded service busbar or service terminal is exposed to inadvertent contact by persons or maintenance equipment while servicing load terminations.

Just learned something. Thanks Robert. I suppose our local AHJs don’t look for that. Time to update my report software.

@mdurante

No my understanding it is NEC requirement.

408.3(A)(2) Service Panelboards, Switchboards, and Switchgear.

Hit refresh.

I don’t think the barrier is required for the grounded conductor.

[rmeier2 (Robert Meier)]

Correct. Not required.
