Residential Sprinkler Pump Protection

Former Community Member
Former Community Member
The British Standard for domestic sprinklers stipulates where a pump is required to boost the water pressure circuit breakers are not to be used for protection. On commercial installations we would have previously used a lockable red enclosure with main switch and MCB. Does anyone have any ideas on suitable solutions for the domestic sprinkler scenarios using a cartridge fuse or similar?

    Yes they can be removed without a tool, and the live contact which SHOULD be the base can then be touched.

    In the UK they should therefore be in an enclosure that requires a key or tool to open.


    One merit of such fuses is that an ES base lamp can be inserted in place of the fuse. If the lamp lights with all loads turned off, then there is a fault.


    Not much used in the UK.
