Wire-nuts provide provide a convenient way to connect household electrical wires inside a electrical work boxes. The packaging includes clear instructions on how many wires of particular thickness can be connected and the length to strip each wire of its insulation. These blue connectors can be used for a minimum of two number 22 wires and a maximum of three number 16 wires. The packaging has a table of allowed numbers of wires of each gauge. The wires can be twisted together before screwing on the connector. It is convenient to have the table as part of the packaging, and I always keep my connectors in the original packaging for that reason.

This review is for a 100 pack of Ideal 72B blue wire nut connectors. The specifications state that these connectors can handle a minimum of two 22 gauge wires and a maximum of three 16 gauge wires. The specifications also state that these connectors are flame retardant up to 221 degrees fahrenheit. The shell of these connectors is ridged to make it easier to turn them. There’s not much else I could say about these connectors but they seem to be a quality product and I’d recommend them for your electrical connections.
