The geothermal heat pumps that I am seeing have one -- or several -- small, circulation pump motors that are located remote from the main unit. Do these circulatory pumps require overcurrent protection or are they internally fused? Also do they require their own means of disconnect? They are not much wattage, if that makes a difference.

Thanks for any advice.

Not to sound like a smart [censored] but what does the manufacturer's installation instructions say.

I just read the schematics and yes, they do have internal fuse protection...thanks!
