Is it a requirement to provide overload protection to a central heating pump rated at 2.77amps?
I’m kinda under impression that an almost 3 amp pump jamming will get rather hot.
I mentioned this to the heating installer who has requested we just installed 2 x isolators for the pumps through a contactor as to not switch the pumps through the programmer which makes sense.
I am aware that the regulations require that a motor 0.37kw requires overload protection of the motor but a pump is not a motor, at least that’s how I view it.
Thoughts please.
