To meet the UL (Underwriters Laboratories)
regulations, a UL-approved copper cable with a
minimum heat-resistance of 140/167 °F
(60/75 °C) must be used.
Use Class 1 wire only.
The units are suitable for use on a circuit capable
of delivering not more than 50,000 rms
symmetrical amperes, 600V maximum, when
protected by T and J Class fuses.
Integral solid state short circuit protection does
not provide branch circuit protection. Branch
circuit protection must be provided in accordance
