Disconnect Switch & Breaker
(OP)
I am working on a cap bank application in a medium voltage system in Canada. Does the canadaian code ( or a local province code)require a disconnect switch infront of the breaker for maintenace reasons?

Utility system or industrial?

Jocelyn VersaVac. It's an industrial type application.
They are not inside MEG type mounted circuit breakers.

Obviously, there would need to be a way to de-energize the breaker for maintenance, and a local disconnect would be convenient.
Also, some safety rules may require a "visible" break to allow maintenance work to be done. But the NEC does not require this.
