CO2 size recommendations

[T.Pedersen]

Hi,

I vaguely remember seeing a recommendation that the 5kg variant instead of the 2kg C02 should be installed where there is 400V+ present; is this correct as I can not find reference to this now? 

Thanks

No, it's an urban myth.

The only reason why you might go for a 5kg for an electrical risk is if the size of the enclosure is such you need the larger volume of gas to flood it adequately.

many thanks for clarifying
