Why Kingston Homes Need a Panel Upgrade
A lot of the housing stock around here was wired for a world without air conditioning, electric ranges, hot tubs, and a garage full of chargers and power tools. If you're living in a century home near Sydenham Ward or an older bungalow in the north end, there's a decent chance you're still running on a 60 amp or 100 amp service, sometimes with fuses instead of breakers. That was fine in 1965. It's not fine now.
We get called out constantly for the same story: homeowner wants central air, or an EV charger, or they're finishing the basement, and the panel just doesn't have room or capacity. Fuse panels also trip up home insurance renewals. A lot of insurers in Ontario have started flat out refusing to renew policies on homes with Federal Pioneer stab-lok panels or old 60 amp fuse services, or they hike the premium until it hurts.
A 200 amp upgrade isn't just about adding breaker space, though that matters too. It's about giving your whole electrical system some breathing room. Modern panels have proper AFCI and GFCI protection built into the breakers, which fuse boxes never had. That's a real safety upgrade, not just a convenience one.
This is one of the more involved jobs we do because it touches the whole house. It's not a same-day, in-and-out service call. It means coordinating with Utilities Kingston for the service disconnect and reconnect, pulling an ESA permit, and usually a few hours without power while we do the swap.
What's Included in a 200 Amp Service Upgrade
Every house is a little different, but a full panel upgrade generally covers:
- Removal of the old panel, fuse box, or undersized breaker panel
- Installation of a new 200 amp main breaker panel, typically 40-42 circuit capacity
- New meter base if the existing one is outdated, corroded, or not rated for 200 amp
- New service mast and weatherhead if the existing mast is bent, undersized, or doesn't meet current clearance rules
- Upgraded service entrance cable from the weatherhead down to the meter and into the panel
- Proper grounding electrode system, including new ground rods and bonding to water piping where applicable
- Bonding of gas piping where required by code
- Load calculation to confirm 200 amp is actually the right size for your home and future plans
- Labelling of every circuit in the new panel, done properly, not guessed at
- Coordination with Utilities Kingston to schedule the disconnect and reconnect of your service
- ESA permit application and final inspection sign-off
- Re-termination of every existing circuit into the new panel, checking for damaged wiring or old aluminum branch circuits along the way
- Surge protection device installed at the panel, which we recommend on every upgrade given how much electronics and appliance boards can get fried by a nearby lightning strike or grid surge
- Cleanup and disposal of the old panel and any asbestos-era wiring insulation debris if present
Panel Upgrades by House Type
Century Homes Downtown and Sydenham Ward
These houses often have a mix of knob and tube remnants, old cloth wiring, and a fuse panel that's been added onto for decades. We usually find surprises once the wall is opened up, like a junction box buried behind drywall with no cover, or a circuit that was never actually grounded. Upgrading the panel is a good time to also address any obvious code violations we spot along the way, even if that wasn't the original scope.
1960s-70s Bungalows in Calvin Park and Similar Neighbourhoods
A lot of these came with 60 or 100 amp fuse panels, sometimes Federal Pioneer or other brands that insurance companies now flag. These are usually straightforward upgrades since the wiring itself tends to be in decent shape, just undersized for modern loads. Basement finishing projects are the most common trigger for these calls.
Newer Builds in Westbrook and Woodhaven
These homes often already have 200 amp service from the builder, but sometimes it's only 100 or 125 amp, especially in homes built before EVs and heat pumps became common. If you're adding a Level 2 charger and a heat pump on top of an electric range and dryer, it's worth having us run a load calculation before you assume the existing panel can handle it.
Rural Properties in Frontenac and South Frontenac
Rural services come with their own headaches: longer overhead runs, older triplex cable from the pole to the house, sometimes underground services that were never mapped properly. We coordinate directly with Hydro One in these cases instead of Utilities Kingston, and timelines can run a bit longer since scheduling a disconnect with Hydro One takes more lead time than in the city.
Condos and Townhomes
Panel work in condos usually needs sign-off from the property management or condo board first, since the service equipment might be considered common element depending on your declaration. We're happy to work with your board's engineer or management company to get the paperwork sorted before we touch anything.
Rental Properties
Landlords upgrading a fuse panel in a rental should plan for at least a half day without power to the unit, and we always recommend giving tenants proper notice. It's also a good opportunity to add smoke and CO interconnected wiring if the unit doesn't already have it, since that's a common gap in older rental stock.
Permits, Code, and Utilities Kingston
Every panel upgrade needs an ESA permit. There's no way around this and no reason to try, since an unpermitted panel swap will bite you when you go to sell the house or file an insurance claim. We pull the permit before we start work, and the ESA does a final inspection once we're done.
The disconnect and reconnect of your electrical service is handled by Utilities Kingston in the city, or Hydro One if you're outside their service area. We coordinate this scheduling as part of the job so you're not stuck making calls yourself. Utilities Kingston generally needs some advance notice, so we build that into the project timeline rather than showing up and hoping for the best.
Current Ontario Electrical Code also requires things that older installations never had, like tamper-resistant receptacles in specific locations, AFCI protection on bedroom circuits, and proper bonding of metal gas piping. When we're already in the panel, we bring the service itself up to code even if some downstream circuits are grandfathered and don't legally need to change.
What Affects the Cost
We don't quote panel upgrades over the phone with a flat number, because there are too many variables that actually change the price. What we can tell you is what drives the cost up or down so you're not guessing.
- Whether the meter base and mast need replacement or can be reused
- Overhead service versus underground service, since underground often means more trenching and conduit work
- Distance from the meter to the panel location, and whether that run is through finished walls
- Number of circuits being transferred and whether any old wiring needs repair along the way
- Whether the panel is moving to a new location in the house versus a straight swap in place
- Access difficulties, like a panel buried in a finished closet or a mast that needs a bucket truck
- Utilities Kingston or Hydro One scheduling and any standby time required

Questions
200 Amp Panel Upgrades: frequently asked questions
Do I actually need 200 amp, or would 100 amp work fine?
It depends on your home and what you're running. We do a load calculation based on your square footage, heating type, appliances, and anything you're planning to add like an EV charger or hot tub. Some homes are genuinely fine at 100 amp for years to come. Others, especially with electric heat or a future EV, need the extra headroom. We'll give you an honest answer rather than upselling you to 200 amp if you don't need it.
How long will my power be off during the upgrade?
Typically a few hours on the day of the swap itself, though it depends on complexity and how quickly Utilities Kingston or Hydro One can do the disconnect and reconnect. We try to schedule this so it's not an all-day event, but we're also honest that it's not a quick in-and-out job like a receptacle repair.
Will my insurance company require this if I have a fuse panel?
Many insurers in Ontario are now requiring an upgrade away from fuse panels and older breaker panels like Federal Pioneer stab-lok, either at renewal or as a condition of a new policy. We can't speak for your specific insurer, but if you've gotten a letter about your panel, that's usually what's driving it.
Do you handle the permit and inspection, or do I need to?
We handle the ESA permit application and coordinate the final inspection as part of the job. You don't need to deal with any of that paperwork yourself.
Can you upgrade the panel without moving its location?
In most cases yes, we can do a straight swap in the same spot as long as there's enough clearance to meet current code, which requires working space in front of the panel and proper height. If the current panel is in a spot that no longer meets clearance rules, like inside a closet with clothes hanging in front of it, we'll talk to you about relocating it.
What happens to the old wiring in my house after the panel is upgraded?
The new panel accepts your existing branch circuit wiring as long as it's in serviceable condition. We inspect each circuit as we transfer it over and flag anything that looks damaged, undersized, or improperly installed. We won't just hide a bad splice behind a shiny new panel.
