Improper maintenance of an electrical system in a building can lead to fatal injuries or death in the workplace. Moreover, neglecting electrical maintenance practices lead to noncompliance with NFPA 70E, which are the requirements for protecting employees from exposure to electrical hazards. Engineers will always include acceptance testing and commissioning of a project to ensure that there are no faults that can prevent a facility from operating. Studies have proved that scheduled maintenance has increased reliability and reduced downtime for commercial industries. Maintenance practices have also protected electrical workers. NFPA demands a qualified electrical worker and insists on the need for safety and skills training for all employees. This article provides four electrical maintenance best practices to know about.
- NFPA 70E Maintenance. NFPA provides that qualified workers should adequately design, install, and maintain any power system for it to be considered safe for operation. NEFPA does not recommend ay maintenance methodology or frequency of managing the power system. Such considerations vary depending on the type of electric system and the company. As a result, the employer should create and implement a maintenance methodology based on manufacturer’s instructions, literature, and the standards of the industry. The employer should also equip the conditions and any requirements needed for electrical maintenance.
- Protective Devices. Due to the increased cases of interfering with circuit breakers, manufacturers created molded and insulated cases. These cases have made it almost impossible to inspect the internal components of circuit breakers. You may invalidate the manufacturer’s warranty if you break the case seal. Since most of these devices are bolted-in, they will increase the time and cost for removal, testing, and reinstallation. Engineers report that 80 percent of the molded cases will not trip for 3-5 years of service. A survey conducted by NETA Circuit Breakers Survey in 2007, confirmed the report made by engineers. As such, it is recommended that workers use these insulated devices to lower their maintenance costs.
- Hazard Analysis. One of the best practices in electrical maintenance is hazard analysis. Once the maintenance manager decides to perform arc flash hazard calculations, he or she has to consider several factors. Hazard analysis takes into consideration the design of the power system; its open time, maintenance condition, and the current protective devices. Most firms use analysis software to perform hazard calculation. The maintenance manager inputs data from site evaluations. The software then calculates and produces warning labels and settings for protective devices. Nevertheless, the software does not consider maintenance frequency, methodology, and procedures.
- Failure of Electric Equipment. Even with regular maintenance, you cannot eliminate equipment failure. Some of these failures can result in substantial production loss or cause severe damage. In case of any electrical equipment failure, you should take up the matter seriously. Conduct a detailed analysis of the occurrence and seek out ways to prevent any future failure of the same nature. You should also report such cases and consult from professionals such as Express Electrical Services.
With these practices in place, you can now work without worrying about electrical issues.
