Ensure the breaker aligns with the panel’s bus stabs and follow the manufacturer’s torque guidelines for the mounting hardware. Since the unit is thermal-magnetic, it responds to both overloads and short circuits in a predictable manner, helping reduce nuisance trips while still providing rapid disconnect when faults occur. Regularly inspect mounting hardware and panel cleanliness to maintain optimal performance in residential, commercial, and light industrial environments.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Amp State","offers":[{"title":"Default Title","offer_id":46349703839906,"sku":null,"price":710.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/general_electric_breaker_and_panel_4894cdc2-fca7-473f-aeed-14ea3a12ba20.png?v=1764154414","url":"https:\/\/www.ampstate.com\/products\/ge-thhqb2120-20a-240v-2-pole-bolt-on-circuit-breaker","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
