Solid plug for a generator cable that your wanting to add a specific plug onto ### ⭐⭐⭐⭐⭐ Good solid connection for house generator plug *by A***R on January 9, 2025* I built a 50A 220v generator cord with this plug. Everything seems well made and should last a long long time. The locking grooves are snug for a good fit into the socket. Everything worked well when I tested it! ### ⭐⭐⭐⭐⭐ Very Solid *by P***M on September 24, 2025* This is a solid plug and very sturdy. It fits the Connecticut Electric 50amp box just fine. This will be used to connect the new generator to the house in the event of a power outage. It took some effort to get the 3/1 #6 wire through the rubber in the black piece but it fits. Using #6 stranded was a little tight due to the shorter length so it will all fit in the housing, but was able to do it. I used a multimeter to make sure there were no cross connections. Haven't had the need to actually try the plug yet. I would recommend this plug. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/396280671-nema-l6-30r](https://www.desertcart.hk/products/396280671-nema-l6-30r) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-05-17*
