Which Wire Connector Should You Use?

In this video we break down three of the most common electrical wire connectors used in residential wiring: wire nuts (also called marettes or twist-on connectors), push-in connectors (often confused with ‘backstab’ connections), and lever connectors (often called WAGO connectors or lever clips/nuts). We explain how each type of connector actually works, where each one shines, and the common mistakes that can lead to bad electrical connections, exposed copper, overheating, or failed splices over time. Topics covered in this video: * How wire nuts / marettes work * Why strip length matters * Push-in connectors vs lever connectors * WAGO-style lever connectors explained * Solid wire vs stranded wire * Why some connectors are reusable and others aren’t * Common electrical connection mistakes * Proper wire stripping technique * How damaged conductors can weaken a connection * Why loose electrical connections create heat * Choosing the right size wire connector We also cover: * Why electricians debate pre-twisting wires before using wire nuts * Why exposed copper below a wire nut is dangerous * How spring-clamp connectors hold wires in place * Why stranded wire changes the type of connector you should use * Why under-stripping a wire can be just as dangerous as over-stripping it Whether you’re renovating your own home, learning basic electrical skills, or just trying to understand the difference between wire nuts, push connectors, and WAGO connectors, this video is meant to make electrical connections easier to understand in a practical, approachable way. As always, electrical work should follow local code requirements and all electrical connections should be made safely and inside approved electrical boxes. 00:00 Wire Connectors Explained 00:36 How to Use Wire Nuts Correctly 01:36 Pre-Twisting Wires: Yes or No? 02:14 Avoiding Wire Nut Sizing Mistakes 03:09 How Push-In Connectors Work 04:15 Push-In Connector Limitations 04:47 Solid Wire vs. Stranded Wire 05:39 How to Use WAGO Lever Connectors 06:43 Lever Connector Mistakes to Avoid 07:42 Inside a Lever Connector 08:47 Which Wire Connector Should You Use? 09:26 Wire Stripping Pro Tip 10:15 Electrical Safety Wrap-Up #Electrical #DIY #HomeRenovation #WAGO #WireNuts #Marettes #ElectricalWiring #DIYElectrical #renovation
