    No it's not, sometime a bell traffo or an RCD can be the cause, but it's not normal and I'd have it investigated IMO. Hopefully the company that wired the place have their details on your fusebaord.

    no, something could be loose or faulty and still "appear" to work, but might not work under fault conditions.

    Is this only happening at night time by any chance?

    This could be a contactor humming (not a problem) or it could be a bad connection arching (potential fire hazzard).
