Bills making their way through Texas’s Senate and House of Representatives will, if passed as currently written, categorize any cabling circuit capable of supplying more than 50 watts of power to be electrical work requiring a licensed electrician. As a practical matter, that would mean any cabling circuits that can support Type 3 or Type 4 power sourcing equipment (PSE) or powered devices (PDs), as defined in IEEE 802.3bt, would fit that definition. As specified in IEEE 802.3bt, a Type 3 PSE provides a maximum of 60 watts and a Type 3 PD receives a maximum of 51 watts, while a Type 4 PSE provides a maximum of 90 watts and a Type 4 PD receives a maximum of 71.3 watts.
