Interconnect Power Supply / Management Regulations & Standards Binder cable connectors Interconnect power standards wireBINDER US K- and L-coded panel mount parts meet the UL 2237 standard for North American power applications. Parts are available within firm’s 824/823 product series – including 5-pin male and female panel mount parts featuring screw locking with a protection level of IP68. Power supply components used in control cabinets in North America must meet UL 2237 standards, which specify testing guidelines for connectors, cables, cable glands, and fuse elements. This includes the Ground Bond Test, which requires the PE path (protection earth) to withstand a current of 190A for the wire gauge AWG16, or 300A in the case of AWG14, for four seconds without interruption. AC applications also require an abnormal-overload test to be carried out at 1.5 times the rated current, during which the PE path fuse must not blow, as well as an additional connection of the PE pin to the component housing.
