Every end is molded and features threaded rings for secure connections, plus visual LED indicators so you can confirm power at a glance. The kit also includes two sealing collars that bridge the paired receptacles to reduce the chance of water intrusion at the mating surfaces.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this Y-adapter let two boats use one 30A outlet safely?\u003c\/h3\u003e\n\n\u003cp\u003eThe adapter maintains the locking L5-30 connection style that prevents accidental unplugging while the molded construction minimizes exposed conductors. LED lights on the adapter quickly verify live power without needing a meter, and threaded rings lock the plugs in place for a secure electrical join.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eMolded plug and dual receptacles reduce loose wiring and wear.\u003c\/li\u003e\n  \u003cli\u003eThreaded locking rings keep the connections tight under motion.\u003c\/li\u003e\n  \u003cli\u003eLED indicators indicate presence of shore power instantly.\u003c\/li\u003e\n  \u003cli\u003eSealing collars provide an added splash-resistant barrier at the junction.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this work with my 30-amp shore pedestal or generator L5-30 outlet?\u003c\/h3\u003e\n\n\u003cp\u003eYes — the Conntek 17220 uses standard NEMA L5-30P (plug) to two NEMA L5-30R (receptacles), matching common 30A twist-lock shore and generator outlets. It does not change the circuit’s electrical rating, so the source pedestal or generator must be able to safely supply the combined load of both vessels.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eStandard NEMA L5-30P to dual L5-30R configuration.\u003c\/li\u003e\n  \u003cli\u003eMaintains original 30-amp wiring and grounding layout.\u003c\/li\u003e\n  \u003cli\u003eDoes not convert voltage or increase circuit capacity.\u003c\/li\u003e\n  \u003cli\u003eIdeal for short-term sharing or parallel connection at the dock.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat are the physical and durability features of this adapter?\u003c\/h3\u003e\n\n\u003cp\u003eThe adapter is three feet long, providing some separation between vessels and making it easier to reach the shore outlet.

It’s built for people who want a compact, lockable, visibly verified connection with added sealing features for dockside conditions — not for permanently increasing circuit amperage or performing electrical repairs. Always follow local electrical codes and the power provider’s rules when using a shared adapter.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I use this to double the amperage from a 30A outlet?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. It splits one 30A circuit into two outputs but does not increase the circuit’s amperage capacity.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Are the connectors water-resistant for dock use?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: The molded ends and included sealing collars reduce water intrusion, but it's not fully submersible—dry and inspect after exposure.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Conntek","offers":[{"title":"Default Title","offer_id":56805956616532,"sku":"B001TNSXE2","price":167.11,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1063\/2652\/4244\/files\/conntek-17220-front-view.jpg?v=1786810900","url":"https:\/\/gardenluxe.co.uk\/products\/conntek-30-amp-shore-power-y-adapter-3-foot-l5-30-plug-to-dual-l5-30-receptacles-with-leds-sealing-collars","provider":"Gardenluxe Uk","version":"1.0","type":"link"}
