Review on ✨ Lever Connectors: 50 Pcs UL Certified 2 Conductor Compact Wire Terminals, Fast Connection 28-12 AWG - Multiple Types by Dave Sidhu

None of the XHF lever connectors are UL or CSA/US listed, so using them for US home wiring (120-240V) is technically a violation of NEC . The WAGO version is UL approved for grounding and equipotential bonding, so it can be used. Revain must state this in the description of this product. UL and CSA approvals are for safety purposes, use of cable nuts not listed may result in a hazardous situation such as fire or electric shock. XHF must obtain security clearance before displaying them as fixtures and electrical wiring in a home.
