Industrial electrical equipment
Pre-assembled cabinets and separate switching devices must be distinguished; current ratings, number of poles, and installation diagrams determine how the goods are described.
Details
- Electricity distribution, protection, and control in factories. Pre-assembled cabinets and separate switching devices must be distinguished; current ratings, number of poles, and installation diagrams determine how the goods are described.
- Specify voltage, rated current, number of poles, protection rating, and cabinet diagram if supplied as an assembled unit. Materials to verify include steel enclosure, conductive copper, and insulating plastic.
- Protect electrical assemblies from moisture; lock cabinet doors and protect busbars, meters, and handles from impact.
- Equipment and pre-assembled cabinets require review of technical requirements and certifications based on their specific configuration and use.
Preparation
- Verify the cabinet diagram and the code of each circuit breaker, contactor, and meter installed in the cabinet.
- Specify voltage, rated current, number of poles, protection rating, and cabinet diagram if supplied as an assembled unit.
- Protect electrical assemblies from moisture; lock cabinet doors and protect busbars, meters, and handles from impact.
