What is a drip loop?

This one’s easy to answer. The drip loop is a slack bit of cable that sits lower than the rest. The whole purpose is to let water pile up at the bottom and drip off. If your cables were tight, water from outside could travel down the wire and get straight into an outlet or onto your electronic devices. If water were to get into an outlet, it could start a fire (ironic, right) by making sparks along the wet areas.

Drip loops and ground blocks are the two easiest ways to make sure that your home is protected. They may not look very attractive but they do their jobs well. Every installation should have a proper drip loop so that water doesn’t travel where it shouldn’t. Even if you live in a dry climate, it’s going to rain sometime. You need that drip loop.
