    Disconnecting means

    Does a non fused disconnect switch loacted first device on load end of utility meter qualify as service disconnecting means?

    Yes. In fact it has to be. There is no other option. But you will need overcurrent protection right next to it. Make sure you have 10K fault current or less.

    I have first device on load end of utility meter is non fused disconnect. Downstream load end of the non fused disconnect first device is panelboard with main breaker. Would that be overcurrent protection right next to non fused disconnect or you are talking about something else?

    Is the disconnect rated as Suitable for Use as Service Equipment (SUSE)? Has to be marked as such.

    Where would I find non fused disconnect rated for use as service equipment?

    Don't have my code book in front of me but IIRC the wording is the OCPD must be "integral or immediately adjacent to" the service disconnect. What is the purpose of the disco?
