How the Work Is Planned
Identify loads and generator limits
We review generator output, fuel strategy, starting loads, essential circuits, and connection location.
Select transfer equipment
The electrician confirms panel compatibility and recommends a listed interlock, manual transfer arrangement, or critical-load solution.
Install, label, and review operation
Equipment is installed and tested, circuits are identified, and the safe operating sequence is explained.
Scope & Limitations
Service covers the agreed electrical connection equipment. Generator sales, engine repair, fuel piping, automatic standby-generator installation, and guaranteed operation of every household load are excluded unless specifically quoted.
Permits & Electrical Code
Transfer equipment must prevent generator and utility sources from energizing the system at the same time. Listed equipment, inlet placement, grounding method, neutral configuration, permits, and inspection must match the installation.
Estimates & Rates
What Affects the Price?
Pricing depends on panel compatibility, generator type and output, inlet distance, wiring route, selected transfer method, and any panel corrections. JL estimates after confirming the equipment.
