Access to components in unmetered sections

[Anonymous]

I have had a member ask the following question.

Scenario:
The clients SLD shows an unmetered MDB that is fed from the unmetered section in an upstream MSB. The clients SLD shows a surge diverter directly taped off from the load side of this Main Isolator in this unmetered MDB.

Question:
Is a surge diverter (inc. associated fuses) that is taped off the main bus in an unmetered section allowed to be installed in a non-sealed section of a MDB for service access? Or does it need to be installed behind a sealed cover/door since it is taken off an unmetered bus?
