Question:
Greetings and thank you for a great forum. Considering NEC Sections 440.8 and 440.14, does either of these rules require or exempt a disconnect means within sight of a mini split air conditioning system remote head that contains the fan coil motor.
Thank you for your consideration.

Hi Kelly,
Thanks for the question. Section 440.8 references 430.87 and 430.112 which both deal with group installations. You installation appears to be a split system with the refrigerant compressor outdoors and the fan coli unit indoors. Section 440.14 addresses the required disconnecting means for the air conditioning equipment containing the hermetic motor refrigerant compressor. The motor in the fan coil unit portion of the split system should follow the applicable rules in article 430 for disconnecting means requirements.
