Frequently Asked Questions
Commercial Electrical FAQs
What types and sizes of commercial electrical projects do you handle?
We handle light-to-medium commercial projects across Mansfield and the DFW area, including tenant finish-outs, retail shops, automotive repair shops, restaurants, medical offices, multi-bay warehouses, and corporate suites. From routine electrical maintenance and breaker panel upgrades to complete commercial electrical rough-ins, our electrical team manages a range of commercial projects.
Can you schedule commercial electrical work after hours or on weekends?
Yes. We recognize that cutting power during normal business hours disrupts employees and costs thousands in lost customer transactions. For main service panel replacements, transformer tie-ins, and disruptive wiring phases, we coordinate evening, early morning, and weekend work schedules to minimize downtime for your business.
What is the difference between single-phase and 3-phase commercial power?
Single-phase power (typically 120/240V) uses two alternating hot conductors and is common in residential homes and small retail storefronts. Three-phase power (120/208V or 277/480V) uses three alternating currents, delivering continuous, balanced power with fewer conductor losses. Three-phase is necessary for heavy machinery, large commercial HVAC compressors, commercial vehicle lifts, and industrial motors.
Do you handle commercial electrical permits and Certificate of Occupancy (CO) inspections?
Yes. All commercial tenant renovations, switchgear modifications, and new branch circuits require municipal building permits. A.T. Electric LLC is licensed with the Texas Department of Licensing and Regulation (TDLR) and registered across Mansfield, Arlington, and surrounding DFW cities. We pull the permits, coordinate directly with city building and fire inspectors, and ensure your space clears inspection for its Certificate of Occupancy.
How often do commercial exit signs and emergency lights need to be tested?
Under NFPA 101 Life Safety Code and OSHA regulations, commercial facilities must perform a 30-second functional test on battery-backup emergency lights every 30 days, and an annual 90-minute full discharge test. We provide commercial testing, replace dead sealed lead-acid batteries, and install modern LED emergency units to keep your business fully compliant.
