Surge Protection & Inspection Intervals

PG
If it is considered that an unskilled person could not, safely, replace an SPD surge module;-

Should the recommended interval until the next inspection be shortened if an SPD is part of the Installation (to take into account the limited operating life of the SPD).

If so, are there any guides to the amount of interval reduction?


Regards

    Acceptably low - or we'd have been fitting them for years already.  Running for a few months with the protection absent is not likely to have much effect. In places where the kit really must be protected, then protection would be cascaded and redundant so that when one lot fails the second remains, and have telemetry installed to report failure. It's in the same league as the self testing RCD - hard to justify in most cases.
