Proposed legislation in Texas would classify some PoE cabling as electrical work

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.

Industrial Ethernet – Learn About

More than half of Industrial Ethernet problems can be traced to cabling. Some of these show up immediately during the startup process – others can allow the connection to function properly until something such as environmental changes cause communications failures. Ethernet is a robust technology that allows communications to continue even under marginal circumstances – but a change in those circumstances might cause communications problems or a complete failure down the road. Here are the most common problems with cabling.
