Higher-Capacity Electrical Services
400-Amp Electrical Service Installations in Delta & the Lower Mainland
Service-capacity planning for larger custom homes, multi-unit projects and properties with substantial electrical loads.
A 400A service is a project decision, not a default upgrade. The requirement should come from the building design, calculated loads, distribution plan, utility requirements and future equipment.
Hundel Electric reviews the project information and coordinates the electrical installation scope around service equipment, meter arrangements, distribution, major loads and construction conditions.
400A service work
Higher-capacity service projects require coordinated details
Load and design review
Use project drawings and equipment information to establish the service requirement.
Utility coordination
Plan around applicable utility service requirements, lead times and approvals.
Meter and service equipment
Coordinate the approved meter and service arrangement for the property.
Main distribution
Plan panels, feeders and overcurrent protection around the building loads.
Grounding and bonding
Include the required grounding and bonding scope for the service installation.
Permits and inspections
Coordinate electrical permits and inspection stages for the approved work.
Capacity by design
Start with calculated demand and distribution—not a preferred amp rating.
The right service size and configuration depend on the complete building load and how power will be distributed.
Load profile
Account for dwelling units, heating, cooling, EV charging, hot water, suites and other major equipment.
Service configuration
Coordinate utility, metering, service equipment and property-specific installation requirements.
Distribution strategy
Plan main distribution, panels, feeders and future capacity around the building design.

Questions & answers
Common questions about 400-amp service installations
Does every large home need a 400A service?
No. Service size should be based on calculated demand, equipment, dwelling configuration and applicable utility and code requirements.
What information is needed to review a 400A service?
Provide drawings, equipment schedules, heating and cooling information, EV plans, unit count, property location and any available utility information.
Is a 400A service simply two 200A panels?
The distribution may use multiple panels, but the approved service and metering configuration depends on the project design and utility requirements.
Can an existing property be upgraded to 400A?
Possibly, but utility availability, service route, meter equipment, existing conditions and building distribution must be reviewed before feasibility or cost can be established.
When should service planning begin?
Begin early in design. Service equipment, utility coordination and construction sequencing can affect both the project schedule and building layout.
Project scope factors
What changes a 400A service project?
Higher-capacity work depends on the utility connection, building distribution and complete load information.
Utility service requirements
Available supply, connection point, metering configuration and utility lead times can shape feasibility and schedule.
Equipment and service route
Meter location, service conductors, equipment ratings and the route into the building affect the installation design.
Distribution and major loads
Multiple panels, dwelling units, EV charging, electric heat and other major loads determine how the service capacity is divided.
