Another portable generator question.

I'm in favor of installing a mechanical interlock on the main breaker on a panel and backfeeding the entire panel from the generator inlet.
However, I looked at a job where I can't do this and would need to install a subpanel and put an interlock on that.
Someone mentioned to use a gentran. I've seen them but favored the interlock instead.
Researching I see the reliance control panels with individual transfer switches.
I called their tech support asking about the panel not having a main overcurrent protection device in it.
He mentioned they have no issues selling them in the states but when they're installed in Canada they need OC protection.
He mentioned they have an inlet with an installed breaker in it.

Does the (portable) breaker on the generator cover nec requirements for circuit/feeder protection feeding a (installed) panel?

Is it ok to assume that all generators would have a overcurrent device?

Thank you

I believe the output breaker on the genny protects its feeder, as long as everything is sized for it.
 
If you're installing an interlock kit on a main breaker panel why would you need to install one on a sub-panel ? The HO has to manage their own loads. I usually tell people to turn off ALL the breakers in the main panel before transferring to generator power. Then turn on one breaker at a time. In your case, they would have to turn off the breaker that feeds the sub panel as well as the breakers in the sub-panel. Once you get to the sub-panel breaker they can turn that on and then one breaker on at a time.

Not what you asked…but the reason I don’t use those panels any more.
The issue I see is the lack of AFCI or GFCI if those circuits require it.

I agree and we've discussed that issue before. Unless it's an old house without any AFCI or GFCI circuit breakers those panels are more trouble than they're worth.
 
It’s an older house with a GE panel. The dimensions for the interlock for the main breaker seem to measure 1/2 larger than the panel cover.

Thought was to add a sub panel and bring the necessary circuits and inlet to that sub panel.
AND to install an interlock to a main breaker and inlet breaker in that sub panel

There are no AF or GFCI breakers.
