What happens here

The Master Electrician defines Low Voltage as any electrical potential from 0 to 50 volts. He points out that many electrical jurisdictions require a specific 'low voltage license' for working with these systems. As an example, he mentions skinny Cat 5E data cables, which are commonly used for Power Over Ethernet (PoE) applications and can safely carry up to 50 volts for network devices or security cameras.

Goal: Learn the definition, range, and common examples of low voltage applications.

What is considered low voltage, what is medium, and what is high? >> Low voltage technically is 50 volts. 0 to 50 volts is low voltage. In fact, a lot of places have a low voltage license. Like that skinny Cat 5e cable that we run. >> Data wire. [music] >> Data wire. We can put 50 volts on that. PoE, power over Ethernet. >> Mhm. >> The medium voltage would be anywhere from 51 to 600 volts. 600 volts is the
