Detail Enclosure Explosionproof
Enclosure Junction Panel Box explosion proof Killark specifications as follow
• Hazardous areas due to the potential of explosive gas atmospheres, combustible dusts or easily ignited fibers or flyings and areas subjected to corrosive or harsh chemicals, weather or dampness • Petroleum refineries, chemical or petrochemical facilities with indoor or outdoor processes • Applications explosion proof panel box requiring overcurrent and short circuit protection of lighting, appliances heating or motor circuits Features Factory Seal between breaker enclosure and termination box eliminates the need for external sealing
• Gasketed covers assure NEMA/ CSA Type 4, 4X rated protection for hosedown and corrosion • Standard Electrical Components: D2L– Cutler-Hammer QC Breakers D2CP– Cutler-Hammer GHC & GCH Breakers • Main distribution block, branch terminal block, neutral and ground bar are located in termination enclosure • Main Lugs. Mechanical solderless type, approved for CU or AL conductors • Solid neutral standard. Single phase, 3 wire or three phase 4 wire • Main and branch circuit breaker handles can be padlocked in “ on” or “ off” position • Top or bottom feed panels available • Breaker chamber hinged cover with quick release – captivated bolts • Termination enclosure has hinged cover with quick release latch for easy opening • Termination enclosure supplied without conduit openings for easy field punching of incoming and outgoing entries • Line and load side of breakers in breaker chamber are factory wired to terminal blocks in termination enclosure and sealed at the factory
• Breaker enclosure is drilled and plugged for maximum number of circuits to permit field addition of unused branch spaces Panel Selection Factors • Basic information required when specifying panelboards is as follows: • Service Requirements – Voltage, phases and frequency • Interrupting capacity • Amperage Rating of Main ( Lugs only or Breaker)
• Branch Breaker Requirements – Type – Number – Poles – Amperage – GFCI Requirements Ordering Information Specifying and ordering a complete panelboard assembly requires the selection of three components
