Your electrical panel is the heart of your home or facility's power system. When it's undersized, outdated, or damaged, it doesn't just inconvenience you — it can create serious safety hazards and prevent you from making improvements like adding an EV charger, a hot tub, or new circuits for a renovation.
As licensed electricians serving Surrey, Langley, Delta, Burnaby, and the rest of the Lower Mainland, we assess dozens of panels every month. Here's what we look for.
"Most Surrey homes built before 1990 have 100-amp service. Today's average household load — with EV charging, heat pumps, and modern appliances — often demands 200 amps or more."
7 Signs Your Panel Needs Upgrading
- Breakers trip frequently: Occasional tripping is normal. If you're resetting breakers weekly — or if a breaker won't stay reset — it signals the circuit is consistently overloaded or the breaker itself is failing.
- You have a fuse box: Fuse boxes are obsolete. They can't be expanded, insurance companies often surcharge or refuse to cover homes with them, and they're a documented fire risk if over-fused.
- The panel feels warm to the touch: Some warmth is normal. Noticeably hot spots on the panel surface or around breakers indicate resistance from loose connections or overloaded circuits — both serious.
- You smell burning near the panel: A burning or acrid smell near any electrical panel is an emergency. Turn off the main breaker and call a licensed electrician immediately.
- Lights flicker when appliances run: Dimming or flickering when a large appliance starts (dryer, AC, pump) suggests the service is too small to handle the load without voltage drop.
- You can't add new circuits: A full panel with no spare breaker slots means any addition — EV charger, new workshop circuits, kitchen renovation — requires a new panel or a sub-panel.
- Your panel is Federal Pacific, Zinsco, or Pushmatic: These brands have documented safety issues and are no longer acceptable under BC code for new work. Insurance companies often flag them specifically.
100-Amp vs 200-Amp Service: What's the Difference?
Service size refers to the total capacity of power flowing into your home or building from BC Hydro. A 100-amp panel can theoretically support 24,000 watts — but that number drops quickly when you factor in continuous load limits and simultaneous use.
Modern homes routinely draw more than this with:
- Electric vehicle charger (up to 9,600W continuous)
- Heat pump or central air conditioning (up to 6,000W)
- Electric range (up to 12,000W)
- Electric dryer (up to 5,500W)
- Hot water tank (4,500W)
That's over 37,000 watts of potential simultaneous load — nearly four times a 100-amp service. Even if you're not running everything at once, upgrading to 200-amp service gives you the headroom to add appliances, charge your EV, and avoid tripped breakers.
What Does a Panel Upgrade Involve?
A residential panel upgrade in Surrey typically involves the following steps:
- Load calculation to determine required service size
- Permit application to the City of Surrey
- BC Hydro application for service upgrade (they need to upgrade the transformer connection at the meter)
- Panel removal and installation of new panel with appropriate amperage
- Reconnection of all existing circuits
- BCSA inspection
- BC Hydro re-energization
The BC Hydro coordination step is important — there's usually a scheduled outage of a few hours on the day of installation. We coordinate this on your behalf.
How Long Does a Panel Upgrade Take?
From permit application to final inspection, a straightforward residential panel upgrade in Surrey typically takes 1–2 weeks. The physical installation work itself takes 4–8 hours. Permit and BC Hydro scheduling are the timeline drivers.
Panel Upgrade Costs in Surrey, BC
Costs vary depending on the panel size, accessibility, and whether the meter base needs replacing. Typical ranges for Surrey residential work:
- 100A to 200A upgrade (standard): $2,200–$3,500 including permits
- 100A to 200A with meter base replacement: $2,800–$4,200
- 200A to 400A (larger homes, EV fleet): $4,500–$7,500+
- Fuse box to breaker panel: $2,500–$4,000
These are ranges — every project is priced individually based on a site assessment. We provide written quotes before any work begins.
Commercial and Industrial Panel Upgrades
Commercial and industrial panel upgrades involve additional considerations: three-phase service, load coordination with tenants, and integration with existing distribution equipment. We have extensive experience with commercial service upgrades across Surrey, Delta, Burnaby, and beyond. Contact us with your facility details for a proper assessment.
