Permit requirements for temporary construction power
Temporary construction services require operating permits.
Temporary construction power requirements vary greatly depending on the scope and size of a project, and configurations of temporary power systems can vary greatly. The most common type of installation involves a temporary pole mounted on site and serviced by an overhead triplex to a 60A, 100A, service box. Distribution can be through a separate load center or in a combination panel in a Type 3R enclosure (examples of acceptable configurations can be found in this information bulletin: Services and Service Equipment).
Why is an operating permit required?
Operating permits allow for better management of permits and equipment. A number of different electrical contractors may be involved at a particular project. A contractor who installs temporary power may not be the same contractor who is hired to do the electrical work for the main project. Responsibility for safety of the temporary power often becomes unclear, and safety can be difficult to monitor and manage.
Who is issued the operating permit?
Operating permits are issued to the equipment owner who can hire an electrical contractor to install the equipment. Once installed, safety of the equipment continues to be the responsibility of the permit holder until the equipment is taken out of service. During operation, the owner can appoint an electrical contractor or an FSR to monitor safe operation of the equipment.
Operating permits step by step
1) The equipment owner obtains an operating permit and appoints a field safety representative (FSR) to oversee the installation and operation of the equipment.
2) A declaration is submitted to the Utility and Technical Safety BC, validating the operating permit for one year.
3) After one year, the permit expires. If the equipment is no longer needed, an ‘all work complete’ declaration of compliance is submitted by the FSR and the permit is closed.
4) If continued operation of the equipment is necessary, a new permit is required.
