What do you all think of this question, (it will be used in a class I am going to teach):
A feeder for a new detached building is requested, the design of which is not entirely known. It is known that it will have provisions for independent living, including provisions for cooking, sleeping and sanitation. The building will be a 'tiny house' that is 500 SQFT or less. The feeder disconnect will be a two pole breaker located in a main house loadcenter. The loadcenter manufacturer identifies and lists all its breakers 60 Amps and up for 75C wire. No other load information is known.
What is the minimum size feeder disconnect?
And what are the minimum size aluminum XHHW-2 feeder conductors; ungrounded, grounded and equipment ground?
