Core Responsibilities

Primary Functions

Respond to residential service calls, diagnose electrical problems using systematic troubleshooting methods, and provide clear cost estimates for repair or replacement work to homeowners.
Inspect and evaluate existing wiring, service panels, grounding systems, and fixtures for safety, NEC compliance, and functionality; prepare prioritized recommendations and defect reports.
Perform panel upgrades and service changes — including 100A, 150A, and 200A panel replacements — swapping breakers, replacing meters, and ensuring proper bonding and grounding per code.
Install and wire lighting systems, switches, dimmers, motion sensors, receptacles, dedicated appliance circuits, and ceiling fans, ensuring proper circuit loading and labeling.
Troubleshoot intermittent faults, nuisance tripping, voltage drop, and neutral/ground issues using multimeters, clamp meters, megohmmeters, and other diagnostic tools.
Repair or replace damaged branch circuit wiring (NM-B, THHN in conduit, MC cable), splice conductors correctly, secure cables, and protect terminations in junction boxes with proper connectors and strain relief.
Install and test GFCI and AFCI protection devices, coordinate with panel breakers and receptacle-level devices to meet NEC requirements and homeowner safety needs.
Install, program, and troubleshoot residential subpanels, transfer switches, and transfer equipment for standby generators; verify transfer operations and load balancing.
Perform meter base replacements, service lateral troubleshooting (in collaboration with utility if required), and coordinate power interruptions with customers and utilities when necessary.
Diagnose and repair indoor and outdoor lighting systems, landscape lighting, low-voltage transformers, and fixtures; replace bulbs, drivers, lenses, and mounting hardware.
Install and wire electric vehicle (EV) charging stations and dedicated circuits, confirm load calculations, and secure necessary permits and inspections.
Conduct load calculations for new appliances, HVAC systems, or remodels to verify service capacity and recommend panel upgrades or dedicated circuits.
Read and interpret blueprints, residential electrical plans, and single-line diagrams; convert design intent into execution while maintaining code compliance and quality workmanship.
Maintain accurate service documentation: work orders, time sheets, change orders, invoicing details, and digital photos for job records and warranty support.
Obtain and maintain required residential electrical permits, schedule inspections with local authorities, and ensure all work passes final inspection.
Provide clear, professional customer education on system operation, safety practices, and maintenance tips; secure customer sign-off and satisfaction before completing service.
Lead small residential crews or mentor apprentices on service calls, delegating tasks, teaching safe installation practices, and ensuring high-quality workmanship.
Manage on-call, emergency, and after-hours service rotations; respond to outage restoration, shock reports, and surge/fault events with urgency and professionalism.
Diagnose issues in smart-home integrations, thermostats, doorbells, and other low-voltage devices that interface with residential electrical systems and coordinate with low-voltage specialists when needed.
Follow and enforce company safety standards including lockout/tagout, PPE use, ladder and fall protection, and confined-space awareness in attics and crawlspaces.
Maintain service vehicle stock: reorder parts, manage inventory of breakers, receptacles, wire, connectors, and common fixtures to maximize first-visit fix rate.
Coordinate with suppliers, subcontractors, and utilities to secure specialized parts, schedule meter work, or resolve supply chain issues affecting service delivery.
Use CRM/dispatch software and mobile tools to manage scheduling, job notes, parts ordering, and capture signatures, photos, and receipts electronically for accurate recordkeeping.

Secondary Functions

Assist estimating and sales teams by providing field-verified scope, time, and material recommendations for residential retrofit, remodel, and renovation bids.
Train customers and junior staff on energy-saving practices, safety devices, and best-use behaviors for installed equipment and new electrical upgrades.
Participate in continuous improvement initiatives: suggest service route optimizations, parts consolidation strategies, and customer experience enhancements.
Support warranty and callback investigations by returning to sites, assessing original repairs, and documenting corrective actions to prevent future recurrence.
Contribute to seasonal preparedness planning (storm response, generator surge demand) and company readiness for emergency residential service spikes.
Maintain professional certifications and attend in-house or vendor training on new products (EV chargers, smart panels, LED drivers) to stay current with evolving residential technology.
