Non separately derived system grounding

Actually it likes them so much it fixed a problem between the NEC, UL and the real world.

Luckily we are not as obsessed with this non-issue as you are.

Did you open the link?

I think you meant to say as "you, NEC, UL are" as I am only repeating what the other two say.

What about all those other things I mentioned in that post you quoted?

These portable generators have never been designed to be connected to a premises wiring system during bad weather. They were designed to be used as temporary power not as an optional standby system as we have tried to use them

Mike, if that's the case why does the FEMA article mention this.

If necessary to connect generator to house wiring to power appliances, have a qualified electrician install appropriate equipment.

And this

Or, your utility company may be able to install an appropriate transfer switch.

...and I suppose these listed devices from the manufacturer are illegal as well.

Because there is a proper way to connect a generator to premises wiring systems and when a portable generator that has receptacles mounted to the frame the only correct way is as a SDS.

What I was addressing was the 15 foot that Ma requires one to be and the dangers of carbon monoxide

not when installed properly but as some install them yes they are non-compliant
They would be no more compliant than a listed 4 square box installed inside a spray paint booth.

This is definitely an issue , though that FEMA link you gave us states that most CO poisoning deaths are the result of generators being run indoors i.e. in garages or basements.

I think it might be a Mass state code, not national, but all dwelling units are required to have CO detectors, one on each level plus within 10' (or 15' ?, would have to look it up) of bedroom doors.
