Adjustable amperage for EVSE - Ontario new bulletin

That is correct, but lets not confuse that with the user app. If it can be adjusted by a "user app" then it needs to wired to max rating. The commissioning software is usually "authorized" persons only such a a factory rep, service technician, etc. So basically the same as the previous "dip switch" rule, just now they have included factory software used by authorized personnel.

What brand allows a user app to adjust amperage settings?

I don't know, but that was the issue previously. A user could "crank up" the output via an app... or at least that is what I understood the issue to be. I don't have an EVC, so I don't specifically know.

The ones I have seen (Flo, Tesla) are set during the commissioning/installation. It is done using mobile software , but it is not an option that the end user can switch easily.

That was the issue from what I understood. ESA assumed it was a simple setting that the end user could easily switch back and forth but it is not. It is just as easy to open the unit and flick a dip switch as it is to get into the software configuring mode and change it so them allowing one and not the other was ridiculous IMO.

All the Tesla ones I have done lately come set to the highest setting and you need to connect to wifi to lower the output and or connect it with the factory if its to be used for revenue generation.

Yesterday ESA released their new bulletins.

Previously we could only wire an EVSE to a lower setting if it was configured using internal dip switches but now, Bulletin 86-1-5 allows wiring an EVSE to a lower amperage setting when it can be set using commissioning amps and software.

The bulletin also allows the use of EVSE that can load share to be on one circuit

This is a big deal and about time. But I can still see issues with the inspectors.
Restricted access shall prevent the user from gaining access to the adjusting means
and shall be accomplished by at least one of the following:
 A cover or door that requires the use of a tool to access the adjustments,
 Unique password protected commissioning apps,
 Software that has a unique password for that site to the adjusting means, or
 The manufacturer can prove restricted access

So if the end user or homeowner has the password, how does this prevent the user from gaining access ?

The same as the possibility of a home owner owning a tool to open a cover to access the adjustments.

I think this only really applies to "hard wired" units, because if they "plug in" we are still back to the receptacle / wire / breaker matching requirement. So unless the unit has a 15-30P or a 6-30P, I think you are still going to have to use the 15-50R or 6-50R installation.
