NEW PRODUCT – Snap-action 3-Wire Block Connector (12-28 AWG) – Pack of 3. These are like the fancy electronics equivalent of the wire nuts electricians use to bind wires together. They are a lot easier to use as well! Each block connector has a metal block inside and three levers that snap open and close to bind stranded/solid-core wire. No screwdrivers required! They’re super handy for free wiring and can handle up to 20A at 300V with UL listing so you can also use them for mains wiring. Use any wires from 12 AWG down to 28 AWG. Each package comes with 3 pieces of 3-wire blocks.

If these act like wire nuts, then the first picture is a BAD idea.

@tango – we’re just demonstrating it with various types of wire we had in the shop. Do not connect hot to neutral (we updated the photo to make it more clear too).

Wago makes a lot of nice terminal blocks. I like the three pole ones with four cavities per pole (862 series).

These are nice to use. I worked a cycle shop installing custom LEDs and these were nice for splitting off wires on components/panels that need to be removed for future servicing areas.
