Residential Electrical Service Replacement

October 15, 2024

A residential electrical service replacement typically involves upgrading or replacing the electrical service equipment in a home to ensure that it meets modern standards and provides sufficient power for appliances and devices. Here’s a breakdown of the process:

Why Replace Residential Electrical Service?

Increased Power Demand: Older homes may have 60-100 amp service, which is insufficient for modern needs. Upgrading to 200 amps or higher is often necessary.
Outdated Wiring: Homes with outdated wiring (e.g., knob-and-tube, aluminum) or old fuse boxes may not meet current electrical codes.
Safety Concerns: Aging panels, breakers, or service wires may pose fire hazards or lead to frequent outages.

What’s Involved in a Service Replacement?

Inspection and Permits: A licensed electrician will inspect the current system and acquire the necessary permits from the local municipality.
Service Panel Replacement: The main electrical panel (breaker box) is often replaced with a larger, safer unit.
Meter Base Replacement: If required, the meter socket (base) where the utility meter attaches to the house is also upgraded.
Service Mast: The pole or conduit running power lines to the house may need replacement if it's damaged or outdated.
Grounding and Bonding: Proper grounding and bonding must be ensured to meet electrical codes and improve safety.
Upgrade in Capacity: The home’s electrical service capacity is increased, usually from 100 amps to 200 amps or higher, to handle more circuits and appliances.

Cost Factors

Panel Upgrade: A panel upgrade (e.g., from 100 amps to 200 amps) may cost between $1,500 and $3,500.
Meter and Service Mast: Adding or upgrading these components can add $500-$2,000 depending on complexity.
Labor: Labor costs will vary depending on region and whether any rewiring or additional work is needed.
Inspection Fees: Fees for permits and inspections can range from $100 to $500.

How Long Does It Take?

The service replacement can typically be completed in a day or two, but the timeline may be extended if there are complications or if a utility company needs to be involved for temporary power disconnection.

DIY or Hire a Professional?

Hiring a Licensed Electrician is critical. Electrical work involves many safety and code compliance issues that most homeowners are not equipped to handle on their own.

Common Upgrades During Replacement

Addition of arc-fault circuit interrupters (AFCIs) and ground-fault circuit interrupters (GFCIs) for enhanced protection.
Installation of a whole-home surge protector.
Upgrading outlets and wiring as needed for more capacity and safety.
