Customer equipment maintenance and isolations

Are you a BC Hydro customer or high voltage contractor who requires an electrical isolation? Does your building's electrical equipment need to be maintained? We have a dedicated team available to assist you.

Dual radial vault requests

Buildings supplied by underground vaults served by two separate distribution circuits – one 'running' circuit and one 'standby' – are a part of our dual radial vault system. We require customers who own or manage dual radial vaults to schedule and complete maintenance on both the running and standby switches every 42 months. Each year we provide pre-determined maintenance window dates to help you maintain the vault within the required timeframe.

This maintenance is performed by an electrical contractor of your choosing. If this maintenance isn't completed, our crews won't be able to restore power in the event of a power outage.

To request an outage, schedule your dual radial vault isolation.

You can learn more in the dual radial vault information bulletin (Last updated: September 19, 2024) [PDF, 1.0 MB].

Isolation requests

If your building has an electrical vault room that's fed from a single primary circuit, we recommend performing maintenance on the electrical vault every three to five years. This maintenance is performed by an electrical contractor of your choosing. For the maintenance to take place safely, our crew is required to complete a vault isolation.

To schedule an outage for maintenance, repair, or testing of equipment for both commercial and residential premises, you'll need to schedule an isolation. The isolation is coordinated with our line department and requires 21 days' notice.

To request an outage, schedule an isolation.

Operating Order requests

An Operating Order request applies to large buildings that have an existing Operating Order with us.A guarantee of isolation is required when maintenance is going to be performed on your building's vault. This maintenance is performed by an electrical contractor of your choosing. The isolation is coordinated through our control centre and requires a minimum of five days' notice, unless otherwise specified in the Operating Order.

To request an outage, submit an operating order request.

Electrical room access requests

If you need access to your electrical vault room for fire alarm testing, submit an electrical vault room access request.
