How to Save Money by Installing Your Own Commercial Electrical Systems

Installing your own commercial electrical systems can seem daunting, but with proper planning and preparation, it can lead to significant cost savings for your business. Here is a step-by-step guide on how to safely and successfully install commercial electrical yourself.

Research and Planning

Before doing any work, it is crucial to fully understand the scope of the project and local electrical codes.

Determine the Scope

• Carefully evaluate the electrical needs of your commercial space. Consider lighting, outlets, machinery, signage, security systems, etc.

• Hire an electrician to provide a professional assessment. They can identify the electrical load requirements and provide recommendations.

• Create a detailed plan indicating the locations for panels, wiring, conduits, outlets, lighting fixtures, etc.

Review Electrical Codes

• Local codes regulate all commercial electrical work. Review your local jurisdiction's commercial electrical code to ensure compliance.

• The National Electrical Code (NEC) also provides key guidelines for commercial electrical systems.

• If needed, consult with an electrical inspector early in the process to discuss code requirements.

Create a Budget

• Determine costs for materials like wiring, conduits, panels, breakers, outlets, lighting, etc.

• Factor in rental fees for large equipment like lifts or trenchers.

• Account for labor costs if outsourcing any complex installations.

• Include permit fees and inspection costs based on local requirements.

Installation Process

Proper safety protocols and step-by-step installation is critical, especially for large commercial electrical projects.

Safety First

• Use appropriate personal protective equipment (PPE) like glasses, gloves, boots, etc.

• Turn off power at the main breaker panel before doing any work. Verify it is off by testing with a multimeter.

• Put up warning signs and barricades in work areas.

• Follow OSHA safety standards, like using GFCI protection and ladders safely.

Install Step-by-Step

• Mount the main distribution panel in an approved location.

• Run feeder wires from the utility connection to the main panel. Large wires may require a lift or similar equipment.

• Install properly-sized circuit breaker panelboards. Connect to feeder wires.

• Run conduit and wiring from panels to switches, outlets, machinery, lighting, etc. according to the plan.

• Install junction boxes, outlets, switches, lighting fixtures, and other components.

• Properly label and color code all wiring.

• Connect equipment like HVAC units, pumps, signage, security systems.

Inspection and Approvals

• Request final inspection by the local building department. They will check for code compliance.

• Make any corrections noted in inspection. Schedule re-inspection if needed.

• Obtain certificate of occupancy or final approval before turning on power.

Maintaining the Electrical System

Take steps to keep your new commercial electrical system running safely and efficiently.

• Test GFCI outlets monthly. Replace any defective outlets.

• Check for loose connections, damaged cords and wires. Perform repairs immediately.

• Update wiring as needed when renovating or adding equipment.

• Have an electrician inspect the full system annually. Perform preventive maintenance.

• Re-review electrical codes and update components as needed to stay compliant.

Installing commercial electrical can be complex, but also rewarding. Stay organized, follow local codes, use proper materials and safety protocols, and inspect finished work thoroughly. This will lead to major cost savings and a trouble-free electrical system for your business.
