Where to Install a Surge Arrester: Best Practices and Guidelines:
At the Service Entrance: This is the first line of defense, capturing surges as soon as the power enters the facility.
At Distribution Panels: Secondary installations at distribution panels help contain any surges that may have bypassed the primary device, offering additional protection.
Near Sensitive Equipment: In environments where critical machinery or data centers are in operation, additional surge arresters may be installed to shield these sensitive loads directly.
