Classroom areas use a basic load of 50 W/m² per Rule 8-204(1)(a). For other areas
(gyms, corridors, cafeteria, admin), enter the applicable W/m². Demand factors default to 100% (conservative) —
verify the applicable demand factors against Rule 8-204 and Table 14 in your code copy before relying on results.
2 · Special Loads (Rule 8-204(1)(b)–(d))
Heating & Air Conditioning
62-118 permits reduced factors for some systems — verify.
Motors — Ventilation, Pumps, Elevators (8-106(1))
25% of the largest motor is added per 8-106(1).
Other Equipment
Taken at connected load, continuous.
EV Charging (EVSE — 8-204(1)(d))
e.g. Level 2, 32 A @ 240 V = 7680 W
3 · Service Characteristics
Not a code requirement — future growth allowance.
Results
Disclaimer: This tool provides a preliminary estimate only, based on the BC Electrical Code
(CSA C22.1:24 as adopted March 4, 2025), Rules 8-204, 8-104, 8-106 and Section 62. Basic-load values other than
the 50 W/m² classroom load, and all demand factors, MUST be verified against Rule 8-204 and Table 14 for the
actual areas and equipment; demonstrated loads (8-106) and utility requirements are not covered. It is not a
substitute for a load calculation prepared by a qualified person and must not be used alone for permit
submissions. Confirm all designs with the authority having jurisdiction (Technical Safety BC or municipal
inspection authority). Elbi MEP Consulting accepts no liability for use of these results.
