Standout: Type 1, code-compliant protection for under $90
Watch out: 25kA per phase is a modest rating
Not for: Square D, Eaton, Siemens or Leviton panels
The ABB THQLSURGE2 is a Type 1 whole-home surge protector that plugs into ABB (formerly GE) panels. It is rated 25kA per phase, has LED status lights and costs about $75 to $90.
What you need before you buy
An ABB or GE panel that takes THQL breakers.
Two free panel spaces.
An electrician to install it safely.
Why whole-home surge protection
It stops large spikes from lightning or the grid at the panel, protecting smart thermostats, EV chargers and appliances. The 2023 electrical code now requires surge protection on new and upgraded services.
