What is the maximum time allowed for interruption of power to each Electric Static Precipitator (ESP) when interlocks are provided?

The maximum time allowed for interruption of power to each Electric Static Precipitator (ESP) when interlocks are provided is two minutes. This specification is critical because maintaining an appropriate operational timeframe for ESP systems ensures that they continue to effectively capture and remove particulates from the exhaust stream of commercial cooking operations.

When the power is interrupted, it can affect the operational efficiency and safety of the system. Two minutes is deemed a sufficient time frame that balances the need to maintain cleanliness and reduce fire risks while allowing for the necessary operational flexibility. If the interruption exceeds this time, it could lead to an accumulation of grease-laden vapors, significantly increasing fire hazards in the kitchen environment.

Interlock systems are designed to enhance the safety of operations by ensuring that equipment operates under safe conditions. The two-minute limit ensures that these safety features are effective in preventing excessive downtime and potential fire incidents associated with improper operation of the ESPs.
