To address issues of temperature rise in Power over Ethernet (PoE) cables, Underwriters Laboratories recently released a Limited Power (LP) cable certification. Most applications won’t require LP cable, but there are a few situations when it may be needed.
When more power is required, the current level running through the cable rises – and the amount of heat generated within that cable increases as well. (Bundled cables are especially vulnerable to higher temperatures; the heat generated by the current passing through the inner cables can’t escape, contributing to higher overall temperatures.) This may reduce cable performance and reliability by pushing cables beyond their rated temperatures.
