Commercial Electrical Preventive Maintenance: What Should Be Included?

Start with an equipment inventory and existing records

Define the equipment covered by the agreement rather than requesting a general “electrical check.” The scope may include service equipment, switchboards, panelboards, transformers, disconnects, motor controls, lighting systems and other distribution equipment serving the property.

• Record equipment identifiers, locations and the areas or operations they serve.
• Gather available one-line diagrams, panel schedules, manufacturer manuals and prior test reports.
• List recurring trips, unexplained interruptions, tenant complaints and previous repairs.
• Identify equipment whose failure would interrupt critical business operations.

Ask the provider to note missing or outdated information. Eaton’s electrical maintenance program overview describes equipment surveys, condition assessments and records as connected parts of a documented program.

Include equipment condition and access

The scope should address enclosure condition, evidence of moisture or corrosion, damaged components and the operating environment. A clean exterior does not establish the condition of internal connections or protective devices; the qualified provider must decide what inspections are appropriate.

Keeping electrical working space accessible is also part of operating the property. Storage should not obstruct required access, and equipment cooling paths need attention. Federal OSHA 1910.303 addresses working space, equipment condition and cooling. Have the electrical professional determine the clearances applicable to the installation rather than applying a single distance to every room.

Specify servicing and testing by equipment type

Ask which inspection, cleaning, servicing and testing tasks are included for each asset. Appropriate work may involve protective devices, insulation condition, connections, controls or other equipment-specific checks. Methods and acceptance criteria should follow the equipment manufacturer and applicable standards.

Do not treat blanket “tighten everything” language as a complete maintenance method. Ask how manufacturer instructions, safe isolation and equipment condition govern the work. Specialist testing should be identified explicitly, along with who will perform it and what records will be delivered.

If thermography is included, define its coverage and limitations. It complements other maintenance; it does not replace all electrical or mechanical testing. Lighting and controls should also be named in the scope if their operation is part of the visit.

Set intervals using the actual equipment and risk

NFPA 70B is the Standard for Electrical Equipment Maintenance. NFPA 70E addresses electrical safety in the workplace. NFPA’s commercial facility safety guidance describes how documented maintenance and safe work practices work together.

A maintenance schedule should reflect manufacturer guidance, equipment condition, operating environment and the consequences of failure. Eaton’s explanation of the 2023 NFPA 70B framework discusses those factors and the role of manufacturer instructions. Have the provider identify the edition and requirements being applied to your program.

Mandatory language within a consensus standard does not mean every provision automatically becomes law for every building. Adoption, regulations, contracts and insurance requirements can affect applicability. Sandia National Laboratories explains these adoption routes. Confirm the applicable requirements; avoid relying on a blanket claim that all electrical maintenance must occur annually.

Plan shutdowns and responsibilities before the visit

Identify the facility contact, affected tenants, acceptable outage windows and equipment that needs a coordinated shutdown or restart. Discuss any temporary arrangements before the work is scheduled. A restaurant’s refrigeration and a manufacturer’s production equipment can have different operational needs even in similarly sized buildings.

Qualified personnel must plan electrical isolation and any justified work involving energized equipment. Federal OSHA 1910.333 addresses deenergizing, lockout or tagging and verification before exposed parts are treated as deenergized. Facility staff can provide records and coordinate access; removing protective covers or attempting internal servicing is not part of that preparation.

Require findings, priorities and closeout records

Agree on the report format before the visit. Ask for the equipment covered, work completed, test results where applicable, omitted tasks and the reasons for omissions. Each finding should identify the affected asset, recommended next action and priority.

Assign an owner and target date to follow-up work. Keep repair records with the original finding so the next provider can understand what changed. Separate immediate concerns, planned repairs and longer-term replacement items in the budget. A report marked complete should mean the visit was documented—not that every recommended repair has already been performed.

Start with a clear scope your team can maintain

For multiple properties, use a consistent record format while keeping each location’s equipment and operating constraints separate. Review the plan when tenants, processes or major loads change. Keep fire alarm, emergency power and other specialized systems visible in the planning process, with their own applicable inspection and testing requirements addressed by the responsible providers.

Gather the current equipment list, known problems and previous reports before requesting a maintenance proposal. Contact Halo Electric to discuss your commercial electrical service needs and priorities, and explore Pro Care service for your facility.
