I am in NH and here thermal switches(I assume your talking Firomatic type) are not required, I usually install them as a matter of safety, however I have had inspectors make me remove them because they are not required.

    Yes

    Spill switch at the draft hood, roll-out switch in an atmospheric boiler and a red plate switch. LWCO if over 300 MBH input (but use your head and do it anyway...) Mass. Electric code also requires a local disconnect in addition to a red plate switch. Some localities require heat detectors/rate of rise above the boiler. All good things in a safety circuit.

    Not a complete list by any means, just what I have seen required in several locations.
