Recently we were having some work done on controls of our MV switch gear (Russelectric). I cannot find anywhere to attach the grounding clusters. There is no accessible connection to the main bus. The only way to access make a connection would be through a breaker. Does anyone have an experience dealing with something like this? I've hear of a device we can buy that you can rack-in directly onto the bus.

Thanks You

Ground and Test device. We build them and also stock plenty of OEM versions. There should be some other manufacturers breaker in the gear.
