EPCOR Distribution and Transmission Inc. (EDTI) has an easy-to-follow process that describes the power connection process and the length of time it typically takes to get connected. If you are looking for a Primary Metered Service, please see the Time Frames Section (5.2) for more information on timing. Depending on the type of connection you need, the entire process can take months to complete. It's important to plan this time frame into your schedule.
It's also important to be aware of any power lines in the area when planning your construction. The required clearance for overhead power lines may be as much as 7.0 metres. You must consider the proximity of planned structures to power lineslines; structures that are too close to power lines can cause serious safety risks. All costs associated with meeting the required code clearances are the owner's responsibility. If the site is deemed unsafe, a stop-work order may be issued. You can get more information on building near overhead lines and learn more at Where's the Line.
The point at which the customer's facilities physically connect to EDTI's distribution system to permit the customer to obtain electricity. For an underground service, this could also be described as the specific point at which EDTI's civil work ends and the customer's begins.
The electrical connection point at which EDTI's service conductors are connected to the conductors or apparatus of a customer.
We've noticed that most new customers need information about specific connections, so we are providing information in that format. Take special note of the maximum service limits. EDTI Customer Engineering Services must confirm all services prior to EDTI granting construction approval. The maximum service limits specified below apply only to dedicated transformers. If multiple customers share a transformer, limits may need to be reduced or alternate servicing arrangements made. Contact us to discuss your particular servicing details.
Maximum service limits apply to services within our 15 kV and 25 kV service areas. For any new or increased services in the 5 kV distribution area, contact us for limits. Refer to Drawing 29 for the primary voltage in your area, and contact us for confirmation.
Mutual heating can affect the number of secondary conductors required, which in turn may limit your choice of service type. See rule 4.004 (d) of the Canadian Electrical Code Part 1 for more information on mutual heating and the Cable Installation Section (2.22) of this guide for information on the maximum number of conductors allowed.
