Electrical & Mechanical Engineering in Whitby.

Elexicon Energy Inc. (Elexicon Energy)

Elexicon's Conditions of Service list the Town of Whitby among its service areas and ask customers to confirm service responsibility with Elexicon. Its OEB licence defines the Whitby Hydro Rate Zone as the Town of Whitby as it stood on January 1, 1968, but places a small number of parcels on Lakeridge Road and Halls Road in Elexicon's Veridian Connections Rate Zone and lists properties on Townline Road West, Ashburn Road North, Dagmar Road and Lake Ridge Road that are served by Hydro One Networks Inc.

For general service metering, a main switch rated above 200 A needs a lockable metal-enclosed metering cabinet or a switchboard compartment for instrument transformers, and services above 800 A need a metal-enclosed switchboard; where switchgear is used, its manufacturer and shop drawings go to Elexicon for approval, and a low voltage switchgear layout must be approved by Elexicon's engineering and metering departments before the equipment is ordered.

The customer provides a meter room large enough for the service entrance and metering equipment, with lighting, a 120 V receptacle and at least 1.2 m of clear working space in front of the meters; Elexicon must be able to reach it at all hours, and exterior access is required so that readings outside business hours do not cause conflicts.

Elexicon decides transformer sizing and the primary and secondary voltages; its standard table runs up to 3000 kVA at 27.6 kV with a 600 V secondary, and demand loads above the listed capacities are assessed on application and may be served by a customer-owned transformer.

Rate zone: Whitby Hydro Rate Zone.

What to prepare

• A completed Service Request Form from Elexicon's website, which is how any new, upgraded or temporary service is applied for in writing, after first discussing available supply, supply voltage, service location and metering with Elexicon
• A scaled site plan placing the building(s) against existing and proposed property lines, neighbouring buildings, streets and driveways, and showing where the gas, telephone, water and cable services run
• Service particulars: civic addresses, the billing customer's name, address and telephone number, the expected energization date, the service amperage, the secondary voltage and the service entrance location
• Load and metering data: estimated initial and maximum kW demand, a single line diagram showing the metering provisions and listing significant loads such as lighting, motors, cooling, heating and welders, a Customer Load Summary where it applies, and an electrical room layout locating the metering equipment
• For energization: the ESA Connection Authorization for the new or modified installation, a signed contract for service, payment of any applicable connection fee and, where Elexicon requests one, a signed Connection Agreement
