Notwithstanding Sentence (1), the intent of Sentence (2) is, in lieu of the separate branch circuit,
installation of a raceway not less than 21 mm running and connecting from the dwelling unit
panelboard to an electrical outlet box located in the storage garage or carport is permitted, if
computing the dwelling unit load that includes the 40 A branch circuit load will result the total
calculated load of this dwelling unit greater than 200 A.

Sentence (3) requires that each one of 20 percent of all parking stalls used by owners or occupiers
of dwelling units in a multi-family building or the multi-family component of a mixed use building
that includes three or more dwelling units must be provided with a receptacle for the purpose of
electric vehicle charging.

Sentence (4) requires that each one of 10 percent of all parking stalls in a commercial building, or
the commercial component of a mixed use building must be provided with a receptacle for the
purpose of electric vehicle charging.

Sentence (5) mandates that the separate branch circuit rated not less than 40 A (@ 208 / 240V)
must be provided to power supply to the receptacle required by Sentences (3) and (4).
Electrical Rooms
Sentence 10.2.3.2.(1) requires that the electrical room in a multi-family building or the multi-family
component of a mixed use building with three or more dwelling units must be designed to have sufficient
space to accommodate future installation of electrical equipment related to the electric vehicle
charging, for the remainder of residential parking stalls that have not been provided with branch circuits
supplying power supply to receptacles for the electric vehicle charging.
CE CODE DEFINITIONS AND RULE
Branch circuit — that portion of the wiring installation between the final overcurrent device protecting
the circuit and the outlet(s).
Outlet — a point in the wiring installation at which current is taken to supply utilization equipment.
Overcurrent device — any device capable of automatically opening an electric circuit, under both
predetermined overload and short-circuit conditions, either by fusing of metal or by electromechanical
means.
Panelboard — an assembly of buses and connections, overcurrent devices and control apparatus with or
without switches, or other equipment constructed for installation as a complete unit in a cabinet.
Raceway — any channel designed for holding wires, cables, or busbars, and, unless otherwise qualified in
the Rules of this Code, the term includes conduit (rigid and flexible, metal and non-metallic), electrical
metallic and non-metallic tubing, underfloor raceways, cellular floors, surface raceways, wireways, cable
trays, busways, and auxiliary gutters.
Electric vehicle charging systems – Rule 86-000(1) This Section applies to the installation of the

EXPLANATION AND CLARIFICATION OF APPLICATION OF THE CE CODE RELATED TO THE VBBL
REQUIREMENTS OF SUBSECTION 10.3.2. FOR ELECTRIC VEHICLE CHARGING
1. When calculating the minimum ampacity of consumer’s service conductors from a supply service
supplying two-family dwellings, one-family dwellings or two-family dwellings with secondary
suites or lock-off units, the size of consumer’s service conductors between the BC Hydro point of
attachment and multi position meter base must be based on the calculated load obtained from
CEC Rule 8-200(2). When determining the main bus rating of the multi position meter base, the
main bus must have the ampere rating sized in accordance with CEC Rule 8-200(2).
2. The minimum ampacity of service or feeder conductors from a main service supplying two or more
dwelling units of, two-family dwellings, one-family dwellings or two-family dwellings with
secondary suites or lock-off units must be based on CEC Rule 8-200(2), as applicable.
3. When the secondary suite of a two-family dwelling building is not individually metered for
electrical power consumption and it is provided with an additional combination panelboard
supplied by panelboard of the principal dwelling unit, the minimum ampacity of feeder conductors
