The Eaton CHSPT2ULTRA is a whole-house surge protector that wires into your breaker panel and absorbs spikes from lightning or the grid before they reach appliances, chargers and smart-home gear. It usually sells for $110 to $185, depending on the seller.
Installation and Cost
- Where it goes: the box mounts on the top, bottom or side of the panel through the 1/2-inch knockout closest to its breaker, or on the wall right next to the panel. Eaton says to keep the wires as short and straight as possible (trimmed to under about 12 inches), because long or bent leads weaken the protection.
- Breaker size: it needs its own 2-pole breaker, in the open slot closest to where the box mounts. Eaton allows a 15A breaker, but you need a 2-pole 50A breaker to get the CHSPT2ULTRA’s full published ratings.
- Who installs it: a licensed electrician (Eaton’s instructions require one). It is a short job, often done alongside a panel, EV charger or battery install.
- Panel brand: because it mounts outside, it works with any brand of load center.
What It Protects
It covers the power wiring for the whole house, including big loads like HVAC and an EV charger. Phone and cable lines are separate paths, so pair it with plug-in surge strips for TVs and computers. Check the status LED after storms; if it goes out, or if its breaker trips, Eaton says the unit needs replacing.
Installation, Climate and Shipping
It goes into your electrical panel or wiring, so it must be installed by a licensed electrician, and many areas require a permit. Check that it fits your panel brand and model before you buy.
It works the same in any climate. Homes in storm-prone areas, with frequent outages or lightning, have the most reason to add panel upgrades and surge protection.
On Amazon it is sold by TOTAL ELECTRIC CORP, a third-party seller rather than the brand, and shipped by Amazon. Check the seller’s rating and return policy before you buy, because the seller on a listing can change. Free delivery was showing when I checked on November 10, 2026.
