Load Center Accessories Line Terminal Barrier QN/QNR Breakers

Beginning January 1, 2017, enhanced UL 67 safety requirements will take effect, applying to all panelboards and load centers with service equipment applications. To comply, any single service disconnect panelboard or load center must have provisions such that, when the service disconnect is opened, no person in the field servicing the equipment load side can make accidental contact to live circuit parts. Barriers to protect against unintended contact shall be constructed in such a way that they are easily installable and removable without contacting or damaging bare or insulated live parts.In addition to meeting new UL 67 requirements, these enhancements will meet the new requirements in Section 408.3(A)(2) of the 2017 National Electric Code. Although these new service barrier requirements enhance the safetyof working on panelboards, Siemens recommends turning off and locking all power supplying these panelboards before working inside to avoid any potential hazards. Electrical equipment should always be placed in an electrically safe condition prior to working inside. Installation and maintenance of this equipment should only be done by a qualified person. Appropriate personal protective equipment (PPE) must be worn and safe work practices must be followed. See NFPA 70E for information on PPE and safe work practices.”,”highlights”:[“Offers protection against unintended contact”,”Meets UL 67 and standards in section 408.3(A)(2) of 2017 NEC”,”Compatible with QN and QNR breakers”
