Preventive Maintenance Guide for Domestic Electrical Connections
21 October 2020
What is preventive maintenance? Any maintenance activity, such as inspection, servicing or replacement, that’s performed as part of a scheduled plan, rather than as a response to a breakdown, can be considered preventive maintenance. And what is the purpose of preventive maintenance? By identifying components or parts that are wearing out and repairing or replacing them before they fail, an effective preventive maintenance program can help limit production downtime and extend the service life of equipment and facilities.
In these theoretical terms, preventive maintenance is a simple idea. But like many simple ideas, it can be challenging to make it a reality. In practice, a preventive maintenance program can be quite complex: there’s a great deal of data to be collected and analysed, and many competing tasks to schedule, prioritize and cost. Here is a preventive maintenance guide for domestic electrical connections.
Inspect lighting on a regular schedule. Make sure your inspection list includes all the lighting in your facility: check all exit lighting for proper installation and function, check all interior lighting for proper installation and function and check all exterior lighting for proper installation and function.
Replace any non-functional lamps you encounter. When lamps begin to fail, consider re-lamping them as a group. You can create a schedule for re-lamping by estimating the average duration of lamp use in a week or a month and comparing that to the expected service life of the lamp.
When replacing lamps, check that the colour temperature to maintain consistency. Dust and clean dirty lamps, and check that they’re aimed as intended. Consider any luminaires that have transformers or control gear. For exterior lighting, check that hardware and cabling is intact.
Domestic Electrical Preventive Maintenance (EPM)
Electrical equipment deterioration is normal, but equipment failure is not inevitable. As soon as new equipment is installed, a process of normal deterioration begins. Unchecked, the deterioration process can cause malfunction or electrical failure. Deterioration can be accelerated by factors such as a hostile environment, overload, or severe duty cycle. An effective EPM program identifies and recognizes these factors and provides measures for coping with them.
In addition to normal deterioration, there are other potential causes of equipment failure that may be detected and corrected through EPM. Among these are load changes or additions, circuit alterations, improperly set or improperly selected protective devices, and changing voltage conditions.
Electrical preventive maintenance requires the support of top management because it is top management who must provide funds to initiate and maintain the program. Maintenance of industrial electrical equipment is essentially a matter of business economics. Maintenance costs can be placed in either of two basic categories: preventive maintenance; or breakdown repairs.
Money spent on preventive maintenance will be reflected as less money required for breakdown repairs. An effective EPM program holds the sum of these two expenditures to a minimum. Electrical preventive maintenance is a form, of protection against accidents, lost production and loss of profit. EPM enables management to place a dollar value on the cost of such protection. An effective EPM program satisfies an important part of management’s responsibility for keeping costs down and production up.
