Check Your Load

200 Amp Service Upgrade

Do I Need 200 Amp Service?

A 100 amp panel may still be suitable for some homes, while others need more capacity for new equipment or renovations. The right decision comes from a load calculation, not simply the number of appliances you own.

Existing Service

100 Amp Panel

Can serve many homes with typical electrical demands, depending on the calculated load.

Typical Household

Lighting, outlets and standard appliances, where the combined electrical demand stays within capacity.

New High-Demand Equipment

An EV charger, heat pump or hot tub may need load management or a service upgrade.

Breaker Space

Available spaces depend on the actual panel model and circuit layout, not just the 100A rating.

Room for Future Changes

Expansion may be possible, but needs a review of existing loads and available circuit positions.

Meter Base & Service Mast

Existing service equipment should be inspected before any proposed changes.

Higher Capacity

200 Amp Panel

Offers a higher service rating for homes whose calculated electrical demand calls for it.

Typical Household

May suit homes with multiple major electric appliances and higher combined demand.

New High-Demand Equipment

Can support plans involving EV charging, electric heating and hot tubs when the load calculation allows.

Breaker Space

Panel sizes with additional breaker positions are available, selected according to the installation.

Room for Future Changes

Higher service capacity can provide more flexibility, subject to future electrical loads.

Meter Base & Service Mast

May require service entrance, meter base or mast upgrades, depending on the existing installation.

More Than Just a Panel Swap

A service panel upgrade is not always limited to replacing the breaker box. An electrical service upgrade can also involve the meter base, service mast, service entrance conductors and coordination with Oshawa Power. We review the existing equipment before recommending the scope of work.

You May Not Need a Full Service Upgrade

For some homes, EV energy management can control charging demand and avoid the need to upgrade to 200 amp service. We'll assess whether it's a suitable option rather than automatically recommending a larger panel.

Panel Safety

Your Electrical Panel: Do's and Don'ts

Small habits around your electrical panel make a difference. Here's what to do, what to avoid, and when to leave the work to an electrician.

✓

Label every circuit

A clear circuit directory helps identify what each breaker controls during maintenance or an outage.

✕

Don't guess which breaker is which

Incorrect labels can leave a circuit energized when someone believes it has been switched off.

✓

Keep clear access to the panel

Leave the panel readily accessible for inspections, maintenance and urgent shutoffs.

✕

Don't box it in behind shelves or drywall

Obstructed access can delay service and interfere with required working clearances.

✓

Confirm the ESA permit is in the quote

A written quote should list the ESA notification and inspection, not leave them as an extra.

✕

Don't hire anyone who skips the permit

Panel work requiring an ESA notification should follow the proper inspection process.

✓

Reset a tripped breaker once, if safe

If there's no sign of damage or overheating, follow the panel instructions. If it trips again, arrange an inspection.

✕

Don't install a bigger breaker to stop trips

An incorrectly sized breaker may leave the wiring without appropriate overcurrent protection.

✓

Test GFCI and AFCI devices

Use the built-in test buttons according to the manufacturer's instructions and recommended intervals.

✕

Don't remove the panel cover yourself

Live components may remain exposed inside the enclosure, even when individual breakers are switched off.

Cost & Timing

How much does it cost to upgrade an electrical panel in Oshawa?

The electrical panel upgrade cost depends on the condition of your existing equipment and the scope of the project. An electrician inspects the installation on-site, explains the required work and provides the price before any work begins. A panel-only replacement can involve different materials and labour than a full upgrade from 100A to 200A service.

Factors affecting the cost to upgrade an electrical panel in Ontario include the meter base and service mast, any panel relocation, grounding and bonding, the number of circuits, AFCI/GFCI protection and applicable ESA requirements. These also affect the electrical panel replacement cost when the service capacity remains unchanged. The written estimate identifies the work proposed for your home.

What's included in the cost to upgrade to 200 amp service?

The cost to upgrade to 200 amp service depends on whether the project involves only the panel or also requires changes to the service entrance. A 100 amp to 200 amp upgrade cost may include a new panel, breakers, service conductors, meter base, mast, grounding and bonding, depending on the existing installation.

The estimate should clearly identify materials, labour, ESA notification and inspection arrangements, Oshawa Power coordination, and any applicable utility-related work or charges. We'll explain the scope and price after assessing the property, before proceeding with the approved work.

How long does an electrical panel upgrade take, and how long is the power off?

The timeline depends on the existing panel, whether service entrance equipment needs replacement, and the required ESA and Oshawa Power arrangements. A straightforward panel replacement and a complete service upgrade can involve different amounts of work.

While the main service is disconnected, the fridge, furnace controls and everything else on the panel are off. After the on-site assessment we explain the sequence and schedule the work, but because reconnection depends on the ESA inspection and Oshawa Power, we don't promise an exact number of hours in advance.

Your Home

Is a 150 amp panel enough instead of 200?

A 150 amp panel may be sufficient for some homes, but the correct service size depends on an electrical load calculation. Your heating system, major appliances, EV charging plans and existing service equipment all need to be considered.

Moving to 200A isn't automatically necessary for every renovation. We'll evaluate whether 150A, 200A or another appropriate approach meets your home's requirements.

Will my insurance company require me to replace a fuse box or Stab-Lok panel?

Insurance requirements vary by provider, the age and condition of the equipment, and the findings of an inspection. Some insurers may request further assessment or replacement of an older fuse box or Federal Pioneer Stab-Lok panel, while others make decisions based on specific documentation.

If your insurer has raised a concern, ask for its requirements in writing. An electrician can then inspect the panel and explain what electrical work, if any, is needed.

Can you move the panel when finishing the basement?

Relocating an electrical panel may be possible as part of a basement renovation, but the proposed location must meet applicable access and clearance requirements. Moving it may also require extending or rerouting circuits, service conductors and grounding connections.

The electrician must assess the current installation and proposed location before confirming whether the relocation is practical and what the work would involve.

Do you upgrade panels in townhouses and condos?

Electrical panel upgrades in townhouses and condos require additional consideration because some equipment may be shared or controlled by a condominium corporation or property manager. The work can also depend on the available building service capacity and access to electrical rooms.

Before planning an upgrade, we review the property arrangement and identify any approvals or coordination required. Not every unit can increase its electrical service independently.

Are there rebates for a panel upgrade in Ontario?

Ontario's Home Renovation Savings Program offers incentives for eligible energy-efficiency improvements, including heat pumps, insulation, smart thermostats and solar equipment. A standalone electrical panel replacement is not currently listed as an eligible upgrade. If your panel work is connected with another renovation, review the current program requirements to determine whether any related improvements qualify.
