Electrical Preventative Maintenance Checklist

Electrical Preventative Maintenance Checklist

Electrical Preventative Maintenance Checklist
The following Maintenance Checks are crucial to most businesses with electrical machinery, large amounts of lighting and other appliances, overhead doors and other expensive assets.

Only properly trained staff or certified electricians should do the following checks. Dangerous current levels, fire hazards and damage to expensive assets are very real threats and need to be well managed.

About 2/3 of Electrical Preventative Maintenance is done while systems are energized. This creates a high potential for danger.
The following are not complete specifications: check each manufacturer’s or supplier’s guidelines.

WHEN TO CHECK
1 month
NOTES
Professional detection equipment can spot problems and isolate which systems need filtering or adjusting

ASSET
Electrical Connections
