6-206 has been interpreted to mean in the suite. Especially if the main is in a room not readily accessible to the Tennant's. IE 24/7/365 without having to awaken or call in a caretaker first. Having said that Who ordered an upgrade? In what province and under what regulation?
Generically if the installation is well maintained and still adequately serves the purpose under which it was approved then there are no requirements to upgrade. see 2-300 to 2-322. Obviously a service upgrade could trigger the Main breaker thing in the suites.
It can be pretty hard to force upgrades without some other legislation besides the current CEC.
In BC for example most Knob and Tube replacements are forced by the Insurance industry who may also require a minimum 100 amp service. These upgrades are not mandated by the CEC at least not if the K&T is in good condition and meets the needs of the residents.
Same with a service size. A modern home must have at least a 100 amp service but in 1963 the 60 was code compliant and if the loads did not change what could justify the upgrade? Only poor maintenance, failure of the service, or a load increase or a law being passed.
You only need a combination panel if the apartment panel is a main service with the neutral grounded. If it comes from a meter bank, the main breaker for the panel is at the meters. If you see a combination panel in an apartment it's because they sometimes cost less.
The panel in the suit isn't a service. The service box is the one in the electrical room with where the neutral is grounded. Try grounding the neutral in the apartment panel and the inspector will call it a feeder circuit. Anyway, that interpretation didn't make it into appendix I, so it's just a regional thing.
The company that owns the apartment building wants the upgrade...we're just giving them a quote for doing it. The owner has been told 2 different things by 2 different companies and has asked me to show them the rule pertaining to this. We're in BC - our first large apartment building job.... Are the panels required to be upgraded with main breakers? If the panels need to be upgraded with main breakers, is that going to require the rest of the apartments to be brought up to code?
I offered 6-206 but the Directive refers to 14-406 which requires a control device to be readily accessible.
This directive can be found on the BCSA website. It answers dodge's question directly as he is in BC so this applys. A combo panel is required. sorry for the wrong rule I referred to in my first try at this question.
14-106 requires overcurrent devices to be readily accessible. Readily accessible is interpreted to be in the occupancy that the circuits serve.
How does putting an overcurrent device in the suite make the overcurrent device in the main electrical room accessible? Does that interpretation not specifically prohibit putting any overcurrent device in the electrical room, including the one that protects the feeder to the suite?
