Notes1. Types of Installation

1.1 Conductor in duct is the standard installation method.

1.2 Direct burial of service cables shall not be used for new installations.

2. Materials2.1 All materials from the stub-off on private property shall be supplied and installed by the

customer. Minimum depth of burial for all ducts shall be 900 mm below the finished grade.

2.2 All materials installed on private property, including the meter socket, shall be CSA certified. However, all material and electrical equipment, up to the utility’s point of connection to the customer-owned equipment, is exempt from the BC Electrical Safety Regulation, including all grounding, duct work, etc. These materials are not the jurisdiction of the electrical inspection authorities, and permits are not required per Technical Safety BC Directive D-El 2017-01.

3. Installation Requirements3.1 General

a. All civil work and grounding installations shall be the responsibility of the customer.

b. All civil and grounding installations shall comply with BC Hydro standards, the BCEC and applicable bulletins issued by the TSBC.

c. The trench shall be in a direct line-of-sight from the property line stub-off to the service duct entry into the building. The base of the trench shall be graded to the depth of the BC Hydro duct stub-off.

d. The service location on the building shall be on the wall closest to Point A (See page 11 & 12), or within one metre back from that wall on either side.

e. The service location on the building and the location of the trench shall be coordinated with other utilities to avoid crossovers and dig-ins, and to maintain clearances.

f. All residential type 400 A and 600 A 120/240 V services shall be installed inside a detached power shed, or an outdoor type pad-mounted power kiosk, or an external closet attached to a dwelling. For all such installations, BC Hydro personnel shall have unrestricted access directly from outside. However, BC Hydro shall not accept 400 A and 600 A residential services installed in an electrical room inside a dwelling, regardless of any unrestricted access for BC Hydro personnel.

g. Commercial and industrial type 400 A and 600 A 120/240 V service equipment located inside a customer building is acceptable.

h. For LPT installations which require CL fuses for 200 A single and 400 A multiple main services, LPT shall be placed on top of pyramid pad to accommodate large service cable bending radii.

i. Free-standing outdoor type support structures for mounting customer service equipment shall be concrete, masonry or rock walls or galvanized steel. Support structures made of treated lumber (except power poles) and plywood shall not be acceptable to BC Hydro.

3.2 Service in Duct

a. The customer shall couple their duct onto the BC Hydro duct stub-off at Point A, except as stated in note 3.2 (f), and discard any markers and/or duct caps.

b. If the length of service duct between Point A and the meter socket enclosure exceeds 50 m, a 332 pull box may be installed in consultation with the BC Hydro designer.

c. If the aggregate duct bends installed on private property to the meter socket exceed 135°, a 332 pull box may be installed in consultation with the BC Hydro designer.

d. The minimum radius of any duct bend shall be 900 mm.

e. The customer is responsible for the installation of adequate service duct drainage, according to the BCEC. Duct sealing to prevent ingress of dangerous earth gases shall be installed by BC Hydro crew.

f. A #8 minimum diameter polypropylene pull string shall be installed in the service duct and tied securely at the meter base enclosure and to the string in the BC Hydro duct stub-off. If no string is found in the stub-off, the customer shall notify BC Hydro for further instructions.

g. Throughout its length, the service duct shall be kept free of any obstructions and foreign material, including sand and gravel. The duct shall be proved by mandrelling, before the final connection is made to the BC Hydro duct and before a pull string is installed.

h. The service duct shall be protected from damage caused by settlement of the foundation and excavation backfill. To minimize settlement and subsequent damage to the service duct and conductor, select backfill shall be used per Section W and compacted in 150 mm layers.

3.3 Residential Supply Service inside a Building Wall

Residential service duct inside a building wall shall be enveloped in, and encircled by, a minimum of 50 mm of concrete per BCEC Rule 6-208. Concrete encasement shall extend up to the meter socket duct terminator because service cables do not have adequate overcurrent protection.

BC Hydro will accept optional installation of Hardi lap siding on top of reduced concrete encasement for improved street appeal of the installation and reduced protrusion of the revenue meter into a side yard. For further construction details of this installation option refer to ES54 S1-01.04.

4. 400 A and 600 A ServicesCAUTION: Due to liability and restricted access, BC Hydro will no longer terminate utility supply conductors directly onto a customer-owned service main switch or breaker lugs.

4.1. BC Hydro standards show the minimum size of service entrance enclosures. Larger size enclosures may be used as required by the customer.

4.2. All service entrance assemblies shall have separate utility service cable compartment. Customer service busbars shall extend into utility cable compartment and fitted with line-side lugs for terminating BC Hydro supply cables.

4.3. Install the U/G service duct on the left-hand side of the meter socket to accommodate the bending radius of the BC Hydro large incoming service cables. For a right-handed connection, please contact the BC Hydro local Design Representative.

4.4. The load-side lug range shall comply to BCEC requirements.

4.5. Line-side lugs shall be tunnel type and shall accept the conductors tabulated in BC Hydro standard ES53 S1-01. All BC Hydro conductors have compact stranding.

4.6. The U/G service duct shall be installed outside the foundation walls, and run on the surface of the finished exterior building walls, unless they are encased in concrete, 50 mm minimum.

4.7. Minimum dimensions shown are required for adequate working space for BC Hydro personnel.
