BCEC 2024 changes that affect your renovation

BC has adopted the BC Electrical Code 2024: the Canadian Electrical Code, 2024 edition, adopted without BC changes this cycle. Every permit we pull is inspected against it. Most changes in the three-year cycle are housekeeping. A few show up directly on homeowner quotes.

AFCI on most living-space circuits

An arc-fault circuit interrupter (AFCI) is a breaker that detects arcing: a nail through a cable, a cracked wire under a staple, a cord pinched behind a couch. Arcing can start fires inside walls, and it often doesn't draw enough current to trip a standard breaker.

Under BCEC 2024, nearly every 15A and 20A circuit feeding living space in new work (bedrooms, living rooms, dens, hallways, finished basements) needs AFCI protection. Some kitchen counter and appliance circuits take GFCI or dual-function protection instead, and sump pumps are handled separately.

• New circuits need AFCI. An AFCI or dual-function breaker is $60–$120 per circuit in parts, versus $10–$15 for a plain breaker. Ten new circuits in a basement suite add several hundred dollars to the job.
• Untouched circuits are grandfathered. The code isn't retroactive. Once we extend or modify a circuit, it has to meet current requirements.
• Old panels complicate it. Older panels like Federal Pioneer may not accept AFCI breakers, so the quote may include a panel replacement. See our Federal Pioneer guide.

AFCI is one code cost I don't mind. I've seen what a stapled-through cable does inside a wall. The breakers occasionally trip on old vacuum cleaners, but they're cheap protection.

Load calculations

Section 8 covers the load calculation, which decides whether your service and panel can legally carry everything on them. BCEC 2024 updated it for heat pumps, EV chargers and induction ranges, which older services were never sized for.

• Stricter for continuous loads. EV charging and electric heating count fully (or nearly fully), not discounted like a range. A 48A charger has to be carried in the calc.
• Credit for load control. If a device stops two loads running at full draw together, the calc counts only the controlled maximum. That can save a homeowner thousands.
• Interlocked loads count once. A heat pump with electric backup, controlled so both can't run flat-out, counts the larger of the two if it's designed and documented correctly.

So a proper quote now starts with a load calc. On a 100A service it decides the whole layout. Our 100A vs 200A guide has a version you can do at home.

Section 86 and EVEMS

Section 86 now formally supports electric vehicle energy management systems (EVEMS). An EVEMS monitors your service and throttles or pauses EV charging when the house needs the capacity.

Before, a 48A charger added 48 continuous amps, and on many 100A services that meant a full service upgrade. Now an EVEMS-controlled charger counts only at its managed limit.

1. Chargers with built-in load management. Several Level 2 chargers meet the EVEMS provisions. They cost a bit more than a basic charger.
2. Standalone EVEMS devices. A monitor at the panel that controls the charger, installed alongside the charger. It usually costs far less than a service upgrade.
3. Multi-unit sharing. Duplexes, townhomes and stratas can share one feeder across several stalls. Stratas, see our guide to EV charging plans for stratas.

The trade-off is slower charging at times. If you charge overnight for a commute, you won't notice. What affects the cost is on our EV charger service page.

What it looks like on your quote

If a line has no explanation, ask which code requirement it comes from. A competent electrician can answer in a sentence. A quote for new living-space circuits without AFCI breakers will fail inspection.
