The cable assembly splits the single 10-30P feed into a four-prong 14-50R and a second 10-30R output, and includes an 8-foot grounding lead to meet modern grounding needs when using the 14-50R. Built with heavy-duty copper conductors and a weather-resistant jacket, it is intended for alternating use of two devices from the same circuit — not simultaneous high-load operation.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the Portvoi splitter keep charging safe?\u003c\/h3\u003e\n\u003cp\u003eThe adapter adds a dedicated grounding conductor for the 14-50R output and uses thick, 10 AWG copper conductors inside a flame-retardant jacket. It is ETL listed and designed for garage or outdoor use, reducing heat and wear under load when used as directed.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e8-foot green ground wire with ring terminal for tying into a nearby outlet ground\u003c\/li\u003e\n  \u003cli\u003eSTW 10 AWG 100% copper conductors for lower resistance\u003c\/li\u003e\n  \u003cli\u003eUV- and flame-retardant outer jacket for outdoor durability\u003c\/li\u003e\n  \u003cli\u003eETL listed housing and molded plugs for improved safety\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this let me charge my EV or run my RV from an older dryer outlet?\u003c\/h3\u003e\n\u003cp\u003eYes — when used correctly, the Y splitter lets you power Level 2 EV chargers (like Tesla and J1772-based units) and standard 30A RV loads by converting the single 10-30P feed into two separate receptacles. Remember that both outputs share the same upstream breaker, so you must not run high-draw devices on both simultaneously.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eProvides one NEMA 14-50R (50A 4-prong) and one NEMA 10-30R (30A 3-prong)\u003c\/li\u003e\n  \u003cli\u003eCompatible with Tesla and J1772 EV charging equipment that accepts 14-50 input\u003c\/li\u003e\n  \u003cli\u003eAllows alternating use of dryer, EV charger, or RV power without plug swapping\u003c\/li\u003e\n  \u003cli\u003eNot for simultaneous full-load operation on both outputs\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow easy is it to install and use this adapter?\u003c\/h3\u003e\n\u003cp\u003eInstallation is plug-and-play — no electrician required for typical use. Plug the 10-30P into your dryer outlet, connect the ground wire ring terminal to a nearby grounded receptacle, then plug your EV charger or RV cord into the 14-50R or 10-30R as needed.

The Portvoi 30 Amp NEMA 10-30P Y splitter is aimed at EV owners, RV travelers, and homeowners who still rely on a three-prong dryer outlet but want a temporary, practical way to power a Level 2 EV charger or a 50A RV inlet without costly panel changes. It suits users who understand shared-circuit limits and need a robust, portable adapter for garages, campsites, or short-term charging scenarios.\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 run both outputs at the same time?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. Both outputs share one breaker; avoid simultaneous high-load use to prevent overloading the circuit.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Do I need to ground the 14-50R?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
