While lightning strikes account for some surges, the majority are caused by switching operations, motors, or disturbances within the grid itself. That\u2019s where a Type 2 surge protector comes in.<\/p>\r\n<p data-start=\"632\" data-end=\"883\">Type 2 SPDs (Surge Protective Devices) are installed in the main distribution board or upstream of UPS systems. Their job is to clamp down on transient overvoltages and safely divert surge currents to ground, keeping your sensitive devices safe.<\/p>\r\n<p data-start=\"885\" data-end=\"1235\">In this guide, we\u2019ll break down how to install a Type 2 surge protector step by step. You\u2019ll learn the tools you need, safety checks, wiring diagrams, and testing methods.
