Success Story: TPD Surge Protection with EMI/RFI Filtering Eliminates Nuisance Tripping

TPD had the opportunity to provide surge protection with enhanced EMI/RFI filtering for a 12,000 square-foot property in Big Sky, Montana that featured an 800-amp service, six sub-panels, and a phase converter powering the chiller system. The homeowners were experiencing random tripping of arc fault and ground fault breakers across the property. Even when the house was unoccupied, breakers continued to trip, causing significant frustration.

The issue was traced to “dirty power” generated by the phase converter. Once a TPD supplied TK-TTLP-1S240-FL unit was installed on the sub-panel feeding the phase converter, the problem was resolved. Nuisance tripping stopped completely, restoring reliability and peace of mind for the homeowners.

This success story demonstrates how power quality is critical in residential homes filled with sensitive electronics, GFCI (Ground Fault Circuit Interrupter) breakers, and GFCI receptacles. TPD’s surge protection products with enhanced EMI/RFI filtering not only protect against harmful surges and interference but also help prevent nuisance tripping of GFCI devices.

Investing in TPD surge protection means peace of mind and long-term reliability. Don’t let power quality issues or nuisance tripping affect your home. For more information on how to install a power quality plan, please contact us at 888-281-7856, info@tpdsurge.com or visit our website!
