A multi-unit dwelling is a structure that consists of multiple individual homes connected on one lot. This could include a duplex, triplex, fourplex or buildings with more units. Within the City of Edmonton these can also be called Multi-Unit Residential Buildings (MURBs).

A multi-meter socket (MMS) involves one power service supply line and is located on one house. From there, each unit has an individual meter that supplies the home. MMS can supply a maximum of four consumer power services.
Note: Where a MMS will be installed and the units will be on individually titled lots, the landowner must ensure that easements with adjacent properties are registered on each title. This shall permit the extension of service cables across adjacent properties, allowing customer access to their service line at all times, and prohibiting the Customer on the adjacent property from taking any action which would interfere with a Customer’s electricity supply.
See section 3.8 of the Customer Connection Guide for more information on easements.
The EPCOR service supply line from utility runs to a single unit
Multi-meter sockets allow up to four individual meter connections
An easement is required when a service line crosses a neighbouring property
Where an individual service cable already exists, multi-metering is not permitted. Please refer to option 2 for further details on individual servicing.

The Customer Connection Guide informs builders and developers about EPCOR standards with regards to service types. This document provides the guidance necessary to successfully request the vast majority of services.
It is necessary to read all the information contained within this document before starting projects to avoid mistakes, errors, and omissions that may result in costly rework and delays.
Note: It is the responsibility of the Customer to meet all requirements of the Customer Connection Guide, and all other applicable legislation, regulations, codes, and guidelines prior to receiving a new connection.
Below is a brief description of two of rules, 8-200 & 8-202, from the 2021 Canadian Electrical Codebook to help with calculating the load for single and multiple dwellings.
Single Dwellings (Rule 8-200): Rule 8-200 outlines how to calculate the load for a single dwelling unit service. These dwelling units are typically single family houses existing on their own separate foundation or property.
Multiple Dwellings (Rule 8-202): Rule 8-202 outlines how to calculate the load for services to multiple dwellings. This includes multiplexes, apartments, and houses with garden suites. It is important to note that this rule states how the additional load per unit will decreases as the number of units increase.
Note: When the additional load that is being calculated is intended to service a basement suit, the calculations must be sent to the City of Edmonton for review.
