Explanatory information on application of CE Code Rule 8-200(2) for the Load Calculation for the Electrical Service related to Lawneway House and One-Family Dwelling; or Laneway House, Secondary Suite and One-Family Dwelling with Secondary Suite. Scope: Canadian Electrical Code, Bulletin and Explanatory Information:

1. The Canadian Electrical Code, Part I, 22nd Edition, Safety Standard for Electrical Installations, CSA C22.1-2012 adopted by the Vancouver Electrical By-Law NO. 5563, Rule 8-200(2) requires that when calculating the minimum ampacity of service or feeder conductors from a main service supplying two or more dwelling units of row-housing shall be based on (a) Subrule (1), excluding any electric space-heating loads and any air-conditioning loads, with application of demand factors to the loads as required by Rule 8-202(3)(a)(i) to (v); plus (b) the requirements of Rule 8-202(3)(b), (c), and (d).

2. The explanatory diagram of Bulletin 2000-042-EL clarifies that the consumer's service conductors between the BC Hydro point of attachment and the duplex meter base must be sized in accordance with Rule 8-200(2) of the CE Code and the ampacity of each consumer's service conductors between each subdivision of the duplex meter base and the consumer's service panelboard of the Secondary Suite and One-Family Dwelling with Secondary Suite must be based on Rule 8-200(1) of the CE Code.

3. The Figure 1 of the Diagram of "Example of Service and Distribution Arrangements for a Laneway House" explains that the consumer's service conductors between the BC Hydro point of attachment and the duplex meter base must be sized in accordance with Rule 8-200(2) of the CE Code and the ampacity of each consumer's service conductors between each subdivision of the duplex meter base and the consumer's service panelboard of the Laneway House and Main Dwelling must be based on Rule 8-200(1) of the CE Code.

Background:

1. The consumer's service conductors between the BC Hydro point of attachment and the multi-position meter

base to be sized in accordance with Rule 8-200(2) of the CE Code. 2. The main bus and each subdivision of the multi-position meter base to have the ampacities that comply with

the requirements of CEC Rule 8-200(2) & (1). 3. The ampacity of each consumer's service conductors between each subdivision of the multiple meter mounting

device and each consumer's panel service box of the Laneway House and One-Family Dwelling; or between Laneway House, Secondary Suite and One-Family Dwelling with Secondary Suite to be based on Rule 8-200(1) of the CE Code. (See Article 9.34.1.1. of the Vancouver Building By-law for additional requirements.)

4. Installation of LWH's service panelboard in the Laneway House to comply with CEC Rule 6-206 and Rule 26-402. 5. The Vancouver Zoning & Development Bylaw No. 3575 has the following definition and requirements:

Laneway House means a detached one-family dwelling constructed in the rear yard of a site on which is situate a one-family dwelling or one-family dwelling with secondary suite.

Section 11, provision 11.24.17 Computation of floor area for a laneway house must include: (d) floor area used for enclosed or covered parking.

6. The service panelboard and branch circuits from a panelboard of One-Family Dwelling or Secondary Suite or One-Family Dwelling with Secondary Suite must not be located and connected to outlets or electrical equipment in the detached one-family dwelling of Laneway House. (See CEC Rule 26-402(1), 26-722(a) and Section 7.3.5.(a) of the Vancouver Electrical By-law No.5563 for additional requirements.)

7. The determination of areas for a detached one-family dwelling of Laneway House must also include the sum of 100% of the area on the ground floor that includes the inside dimensions of the area used for enclosed parking for the purpose of CEC Rule 8-110 and Rule 8-200(2).

8. The maximum floor area of a laneway house is determined by multiplying the lot area by 0.16. This results in maximum unit sizes of approximately 56 m2 (644 ft2 ) on standard 33’ x 122’ lots, and 84 m2 (900 ft2) on 50’ x 122’ lots. The maximum size of a laneway house is 900 ft2, regardless of lot size. These floor area limits include upper and ground floor living space as well as enclosed parking (where it is provided).

More Definitions: Row housing - means a building of residential occupancy where no dwelling unit is located above another dwelling unit and there is no

common interior or exterior means of egress. [VBBL 2007]

Dwelling Uses - means and includes the following uses, and any one of them, but no other: [Zoning & Development Bylaw 3575] Freehold Rowhouse means a dwelling unit, in a row of at least three side by side dwelling units, which shares a party wall with an adjoining dwelling unit, and is located on its own lot which abuts a street and a lane. Two-Family Dwelling (Duplex), Infills, Multiple Dwelling (Triplex, Quadruplex) should not be considered to be row-housing for the application of CEC Rule 8-200(2).
