Electric power drives every part of a business—lighting, HVAC, networks, production lines, kitchens, and point-of-sale. When systems fail, work stops. Hiring a licensed commercial electrician keeps your building safe, compliant, and online.
Chamberlin Electric plans, installs, and maintains commercial electrical systems across New Hampshire. We coordinate permits and inspections, meet current codes, and build in efficiency so your facility runs reliably and economically.
What a Licensed Commercial Electrician Does
Licensed commercial electricians handle larger loads, higher voltages, and more complex controls than residential work. Typical responsibilities include:
- Designing and installing power distribution for new construction and expansions
- Upgrading panels, feeders, and branch circuits to support modern loads
- Maintaining switchgear, panels, lighting, and emergency systems
- Troubleshooting faults to minimize downtime
- Ensuring compliance with local and national codes and the Authority Having Jurisdiction (AHJ)
Why Licensing Matters
Licensing confirms training, testing, and accountability.
- Safety & Compliance: Work follows the NEC (National Electrical Code), OSHA safety rules, and local AHJ requirements.
- Insurance & Liability: Many policies require licensed contractors for coverage and claims.
- Reliability & Cost Control: Professional installations run cooler, last longer, and reduce emergency calls.

Maintenance = Fewer Emergencies
A short planned outage costs less than an unplanned one. Annual inspections and targeted replacements reduce heat, arcing, and failures—and help you budget upgrades on your terms.
FAQs
What’s the difference between residential and commercial electricians?
Commercial work handles higher loads, complex controls, and life-safety systems common in offices, healthcare, restaurant, and industrial facilities.
How often should my system be inspected?
Annually for most facilities; more often for older systems or heavy-duty loads.
Can you help reduce energy costs?
Yes. LED/controls retrofits, power monitoring, and corrective maintenance lower consumption and extend equipment life.
Do you pull permits and manage inspections?
Yes. We prepare permit documents, coordinate with the AHJ, and meet on site for inspections.
Do you provide emergency service?
Yes—24/7 coverage statewide.
