The triple-aluminum, stranded design offers both flexibility and strength, making it easier to pull through trenches and conduit without compromising performance. The 600V rating supports typical residential or light commercial feeders, while the 200A ampacity accommodates substantial loads common to modern homes or small facilities.\u003c\/p\u003e \u003cp\u003eKey use scenarios include supplying a detached structure, powering a subpanel in a shop or outbuilding, or running feeders from a transformer to main or sub panels in underground configurations. The direct burial capability reduces clutter and protects the conductors from the elements, and the flame-retardant jacket adds an extra layer of safety in underground environments.\u003c\/p\u003e \u003cp\u003eWhy choose this Southwire triplex underground cable over alternatives? The integrated triplex configuration keeps the conductors neatly arranged and evenly spaced, simplifying pulling and installation. Aluminum conductors strike a balance between strength and cost, and the combination of PVC insulation with a polyethylene jacket delivers dependable moisture resistance for subterranean use. UL listing offers assurance for compliance with electrical codes, while the wet-location suitability ensures reliability in damp soil and trench conditions.\u003c\/p\u003e \u003cp\u003ePractical installation notes: plan for a clean, straight pull and use appropriate connectors, terminations, and protection where the cable enters buildings or equipment. Adhere to local electrical codes for burial depth, trench width, and protection from physical damage. With 500 ft on a spool, you can cover substantial underground runs with fewer joins, reducing potential points of failure and easing future maintenance.\u003c\/p\u003e \u003cp\u003eIn short, this Southwire 500 ft. 4\/0-4\/0-2\/0 Stranded Triplex Underground Cable delivers robust underground power distribution with proven durability, code-compliant safety features, and the practical flexibility needed for reliable outdoor electrical feeders.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Southwire","offers":[{"title":"Default Title","offer_id":52218380026130,"sku":"3015047","price":4.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0928\/1024\/8466\/files\/3015047_A.eps_High.jpg?v=1777077272","url":"https:\/\/nationalhardwaregroup.com\/products\/southwire-500-ft-4-0-4-0-2-0-stranded-triplex-underground-cable","provider":"National Hardware Group","version":"1.0","type":"link"}
