The SIEMENS NBK06 is a number strip accessory covering the 127-168 numbering range, designed for use with compatible Siemens panelboard and load center systems. Number strips provide clear circuit identification labeling inside electrical panels, allowing electricians and service technicians to mark and reference individual breaker positions quickly and accurately. This small but essential accessory supports organized, code-compliant panel documentation and is typically installed during new panel wiring, breaker additions, or panel re-labeling projects.
The NBK06 number strip is suited for residential and light commercial electrical panels where circuit directories and breaker position identification are required. It is installed by licensed electricians during panel builds, service upgrades, or circuit additions where clear labeling of positions 127 through 168 is needed. Proper circuit identification supports NEC compliance for panel directories and simplifies future service calls.
Designed as an OEM-style accessory number strip for compatible Siemens panelboard and load center enclosures requiring position identification in the 127-168 range.
Installation is performed by a licensed electrician. Always de-energize the panel and follow lockout/tagout procedures before opening the enclosure or working near energized bus bars. Number strips are inserted into the designated label slots on the panel interior door or directory card holder. Consult the NEC and local authority having jurisdiction for requirements on circuit directory labeling.
