Low Voltage Booster Box
Splice this booster into a vacuum's low voltage wiring system, plug it into 110 volts, and your 24 volt line will be boosted with plenty of juice! The two blue wires connect to your power unit low voltage (you can use speaker wire to extend any of the wire here) and the red and yellow (or two red) wires connect to the low voltage leads coming from the install site. Simply hang the box on your wall with a nail into a stud. Be sure to use wire nuts to get good connections when joining the wires together.
