It carries a 22,000-amp interrupting capacity (22kAIC) and is housed in a NEMA 3R rain-tight enclosure, making it suitable for outdoor or covered exterior installations. Licensed electricians install this unit as the main distribution point between the utility service entrance and branch circuits throughout a structure. The 40-circuit capacity accommodates a full complement of single-pole and double-pole breakers for standard residential builds or small commercial panels.\u003c\/p\u003e\n\u003cp\u003eThis load center is intended for single-phase, 3-wire service entrance or distribution applications in residential and light commercial settings. Its NEMA 3R enclosure rating protects internal components from rain, sleet, and ice formation, making it a common choice for detached garages, outbuildings, pool houses, and other outdoor-fed structures where weather exposure is a factor. The 200-amp main breaker configuration and 40-circuit count align with current residential service sizing requirements in most jurisdictions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e200-amp main breaker rating supports full residential service entrance loads\u003c\/li\u003e\n  \u003cli\u003e40-circuit capacity for single-pole and double-pole branch circuit breakers\u003c\/li\u003e\n  \u003cli\u003e22kAIC interrupting capacity meets NEC requirements for most residential applications\u003c\/li\u003e\n  \u003cli\u003e1-phase, 3-wire (1P3W) configuration at 120\/240 volts\u003c\/li\u003e\n  \u003cli\u003eNEMA 3R rain-tight enclosure rated for outdoor and exposed installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style single-phase load center for 200-amp residential and light commercial electrical distribution systems requiring a NEMA 3R outdoor-rated enclosure.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. Utility power must be confirmed off at the service entrance before any wiring connections are made inside the enclosure. Verify that conductor sizing, grounding electrode connections, and neutral bonding comply with NEC Article 230 for service entrance equipment. Do not exceed the rated 200-amp main breaker or 22kAIC fault current values for the installation site.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMain Amperage Rating\u003c\/strong\u003e: 200 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCircuit Count\u003c\/strong\u003e: 40 circuits\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePhase Configuration\u003c\/strong\u003e: 1-phase, 3-wire (1P3W)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 120\/240 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterrupting Capacity\u003c\/strong\u003e: 22,000 amps (22kAIC)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnclosure Rating\u003c\/strong\u003e: NEMA 3R Rain Tight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 783164113167\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ABB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TM4020RCU\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":51383511580978,"sku":"TM4020RCU","price":585.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312672026.png?v=1782598962","url":"https:\/\/voomisupply.com\/products\/abb-tm4020rcu-200a-40-circuit-load-center-120-240v-nema-3r","provider":"Voomi Supply","version":"1.0","type":"link"}
