    Two questions
    1: 100/32A switch fuse
    There are 16 such switch fuses in an electrical room.
    The notation is 100/XXA where XX varies from 80A to 10A

    My interest is trying to see if they are a possible proxy for energy use as the budget wont stretch to sub-metering them all.

    Any thoughts in the cost associated with extracting a pulse output from these meters.
    There is a data logger on the other side of the room so a wired solution would work.
    Thanks as always

    It would be a 100amp rated holder and unit but fused down to 32amps.

    It's used to maintain some capacity in the system if you needed to expand it out

    You couldn't fuse above the 100 amps

    well, I suppose you would submeter the ones with the highest amps as a priority. It isn't necessarily true that the ones with the highest amps use the most kWh though. It depends whether the load is continuous or intermittent.

    DIN Submeters are not very expensive, if you have somewhere they can be easily wired and if you have a qualified person available to fit them.

    It is a project for an electrician who knows what he's doing. If he knows what's on the circuits, he should be able to tell you which ones are worth sub metering.
