Two projects that solve different problems.
A panel replacement may be appropriate when the service entrance and meter equipment remain suitable. A complete upgrade addresses the power path from the utility connection through the home’s distribution equipment.Read service-upgrade answers →200-amp service upgrade
Service entrance, approved meter and main equipment, feeder, panel, surge protection, grounding, bonding and coordination as required by the actual design.
Targeted or managed load
When one new load drives the conversation, review whether a suitable circuit or compatible load management solves the need before assuming a complete upgrade.
When 200 amps becomes the stronger plan
Condition, capacity and what comes next.
Equipment condition
Age, corrosion, heat damage, unsuitable equipment, limited space or grounding concerns can make complete modernization more valuable than another focused repair.
Several new loads
EV charging, heat pumps, electric cooking, pools, additions and renovations should be planned together so the service and panel are not outgrown one project at a time.
A Seafield installationThe complete power path
Six parts. One coordinated project.
Utility connection
Identify overhead or underground delivery and plan around applicable PSEG Long Island requirements.
Service entrance
Review the attachment, weatherhead, raceway and conductors where an overhead service applies.
Meter + main equipment
Select approved equipment and organize the exterior service disconnecting arrangement.
Feeder + panel
Transfer, organize and label circuits in compatible distribution equipment.
Grounding + bonding
Review grounding electrodes, water-pipe bonding and the neutral-ground arrangement as one system.
Surge + documentation
Install whole-home surge protection, torque, test, label and complete the inspection and utility process.

Questions before an estimate
Understand what you are approving.
Browse the full Ask Seafield library →What is included in a complete 200-amp service upgrade?
The final scope follows the existing home and approved design. A complete project can include the service entrance, meter and main equipment, feeder conductors, distribution panel, whole-home surge protection, grounding and bonding, circuit transfer and labeling, permits, inspection and utility coordination.
Is a panel replacement the same as a service upgrade?
No. A panel replacement changes interior distribution equipment. A complete service upgrade can also change the service entrance, meter equipment, main disconnect, conductors, grounding and utility connection. Seafield identifies which scope solves the actual condition before pricing it.
Does every 100-amp home need a 200-amp service?
No. The recommendation should follow equipment condition, calculated demand, panel space and realistic future loads. A targeted circuit, panel work or compatible load management may be appropriate in some homes.
How long will the power be off?
A planned upgrade requires a coordinated outage. Most residential installations are completed and ready for reconnection within one working day, subject to the approved scope, utility coordination, inspection and site conditions.
Are permits and PSEG Long Island coordination included?
The proposal states the exact filing, inspection and utility-coordination scope. Seafield plans complete service work around the adopted requirements, local inspection process and PSEG Long Island requirements applicable to the property.
What photographs help with the first review?
Safe exterior photographs of the meter and utility connection, plus the closed panel, main-breaker label and surrounding wall, are most useful. Never remove a cover or touch service equipment to take a photograph.
