Did you know that running to failure can cost up to 5 times as much as implementing a routine proactive, preventative maintenance schedule? If your non-seg bus system has not been inspected by qualified personnel in the last 18-24 months, there is a good chance that your system is at risk. Routine bus duct maintenance and inspection, by qualified and trained personnel, is the most effective way to maintain the health of these system critical electrical components and mitigate opportunities for a forced outage. In fact, 100% of clients who have relied on EBI for bus duct maintenance have avoided a forced outage! If you have an upcoming maintenance outage planned, have critical projects that require bus duct expertise, have fabrication needs, or would like to learn more about extending the life of your electrical assets, contact us today.
