"Each electric motor having a rating exceeding 370 W shall be provided with
control equipment incorporating means of protection against overload of the
motor."

Does each need its own motor overload protection? Or can you use a single motor overload for multiple items?

Doesn't say "individual" or "dedicated" or "separate" means of protection;
or any other wording that would require the protection for one motor to be only for that motor.

Not unheard of for several motors of a system to share common control / protection devices,
but needs care to get it right
