Portable Generator Signs One Family Home

[infinity]

I've been looking at the requirements for signs and how they've changed from the 2017 to 2020 NEC. Under the 2014 and 2017 when installing a generator inlet we would put a sign on the service equipment stating that there was an alternate power source. It looks like this is no longer required under the 2020 NEC unless you interpret the "optional standby power source disconnect" to be the inlet.

2017:
702.7 Signs.
(A) Standby. A sign shall be placed at the service-entrance equipment that indicates the type and location of each on-site optional standby power source. A sign shall not be required for individual unit equipment for standby illumination.

2020:
702.7 Signs.
702.7(A) Standby.
A sign shall be placed at the service-entrance equipment for commercial and industrial installations that indicates the type and location of each on-site optional standby power source. For one- and two-family dwelling units, a sign shall be placed at the disconnecting means required in 230.85 that indicates the location of each permanently installed on-site optional standby power source disconnect or means to shut down the prime mover as required in 445.18(D).

Interesting. No signs for portable generators

It was my understanding that portables never required that signage.

There is the requirement for signage indicating bonded or floating neutral.
