CEC Rule 8-200 Optional Method

Ghost Load Auditor

Determine whether your existing electrical service can safely carry a heat pump, EV charger, and full residential load — before you commit to equipment or permits.

Defaults pre-loaded for a typical 2,700 ft² BC home on a 100A panel.

Technical Beta

Ghost Load Auditor is currently in Technical Beta. Results are for planning purposes only and do not constitute engineering advice. FSR verification required for permit submissions.

ESTIMATE ONLY — Results are informational and do not replace a site assessment by a Licensed Electrical Contractor or FSR.

Property & Load Inputs

Living area (sq ft)

= 250.8 m²

Service size (A)

Major Appliances

Range / Cooktop (W)

Dryer (W)

Water heater (W)

MUA / Kitchen Makeup Air Heater (W)Ghost Load

Electric heater for high-CFM kitchen exhaust makeup air. Enter 0 if not present.

HVAC — Only the larger load is applied (CEC 8-106 Interlock)

Heating load — ASHP heat strip / MUA (W)

e.g. 15,000 W = 62.5A auxiliary heat strip

Cooling load — AC / ASHP cooling (W)

e.g. 5,000 W = 1.5–2 ton condenser draw

EV Charging

EV charger (W)

11,520 W = 48A Level 2 EVSE (typical dual-head)

Load management enabled (EVEMS)
Shows Scenario B: EV excluded from calculated load per CEC Rule 8-106(11)

Site Elevation & Dual-Fuel System

Site elevation (metres above sea level)

Vancouver ~0 m · Kelowna ~344 m · Kamloops ~345 m · Prince George ~575 m

Residential Dual-Fuel System
Heat pump + gas furnace — enables altitude derate & COP crossover analysis

Planning a heat pump install? The quote looks fine — until your electrician says you need a panel upgrade. Find out before it happens.
