Important points to know:
- Temporary power is required for construction (single phase, three phase, or both).
- Partial energization of the building is not allowed.
-
Permanent power will not be provided until:
- Electrical inspection requirements are completed.
- All meter sockets are properly labeled (see labeling standards below).
Meter Labeling Standards:
- Labels must be permanent (e.g., no tape or marker).
- Labels must be legible and visible.
- Labels must not be placed on the socket cover.
Once all sockets are labeled and facilities are ready for permanent service, contact your assigned Minnesota Power representative to request scheduling of permanent service activation. For questions, please contact Minnesota Power's Construction Center.
Service with Transition Cabinet
The preferred option is to lock out the main for the apartment metered services for customer safety. Minnesota Power will install a transformer lock on the main alongside the electrician lock-outs. The lock will be removed when an electrician is ready to energize all apartment meters. The customer/electrician is responsible for energizing the main disconnect after the lock is removed.
Key Details:
- All sockets must be properly labeled, and meters will be taken simultaneously.
- Minnesota Power will not allow energizing one unit, wing, etc. at a time.
- Permanent power can be run to the transition cabinet to provide temporary power, or separate temporary power can be received through the transformer.
- A Minnesota Power lock will be installed on the transition cabinet.
- Cable terminations for apartment metering are not to be connected during construction.
- Once construction is complete, the remaining power can be connected when all sockets are properly labeled.

Preferred and alternative transition cabinet options.
Service with No Transition Cabinet
If there is a full separate service for house power that is not integrated with apartment metering gear, the house power can be energized for temporary service while apartment metering is not connected in the transformer. Once construction is complete, the remaining power can be connected when all sockets are properly labeled. All meters will be taken simultaneously.
If the service has all customer gear — house and units — integrated into the same gear behind the main, the customer must make all accommodations for single-phase or three-phase power needs separately at the outset. Minnesota Power may construct and energize the permanent power service to use for temporary power during construction. However:
Important Restrictions:
- Permanent service may not be energized until all meter sockets are properly labeled and meters are ready to be taken for the entire development.
- Minnesota Power will not allow energizing one unit, wing, etc. at a time.
