Dramatically decreases the likelihood of ground faults and short circuits. Saves hours of installation, start-up, and troubleshooting time. Proven to be able to allow pass-through conductors, which may reduce conduit. Reduces need for adjacent junction boxes. Allows an upgrade to a speaker or chime strobe system without replacing the box if used on horn circuits; thereby, creating an easily upgradeable system for owners---with tremendous future cost savings!
