Electrical Panel Upgrades & Service

Why Upgrade?

  • Outdated Panels: Older panels may not handle the increased demand of modern appliances, HVAC systems, or electric vehicles.
  • Safety: Old or faulty panels can pose a risk of electrical fires, power surges, or other hazards.
  • Capacity: Newer panels provide more circuits and higher amperage to support new electrical needs.
  • Code Compliance: Panel upgrades may be required to meet current electrical codes, especially during home renovations or additions.

When Should You Upgrade?

  • Home Renovation: Adding new appliances, outlets, or dedicated circuits like for EV chargers.
  • Frequent Tripped Breakers: If circuits trip regularly, it indicates overloading.
  • Increased Energy Usage: New HVAC systems, electric vehicles, or home additions demand more power.

Flickering Lights/Voltage Drops: These signs often indicate an overloaded or failing panel.

Types of Electrical Panels

Main Breaker Panel

Purpose:
Controls the power supply to your entire home.

Includes:
A main disconnect switch and individual circuit breakers.

Use:
Standard for most homes — protects and distributes power to all circuits.

 

Main Lug Panel

Purpose:
Similar to a main breaker panel but
does not have a main disconnect switch.

Use:
Often used as a
sub-panel (secondary panel) or in multi-unit buildings.

Note:
Requires a main breaker upstream (like in the main panel).

Sub-Panel

Purpose:
Extends power from the main panel to another part of a property (garage, workshop, addition).

Use:
When the main panel doesn’t have enough room or when separating areas by circuit.

Note: Fed from the main panel. Has its own breakers.

Transfer Switch Panel

Purpose:
Connects a
backup generator to your home’s electrical system.

Types:
Manual or automatic.

Use:
Essential for homes with generators to safely switch between grid and generator power.

Choosing the Right Panel

  • 100 Amp: Small homes or apartments with low power needs.
  • 150–200 Amp: Standard for modern homes (can handle HVAC, appliances, EV charging, etc.).
  • 400 Amp: Large homes or homes with workshops, multiple HVACs, or high electrical demand.
