There a question on the exam asking how many feet clearance does the condenser coil have to be? They provided a diagrm, and the answer are 2,3,4 feet. Please help

[Admin]

The condenser coil is considered a source of ignition and would have to be 3' (1m) from the discharge of relief devices.

Clause 5.5.9 - The discharge from relief devices shall terminate outdoors with the clearances specified in Table 5.2.

An OPCO regulator would reduce this clearance to 1' (0.3m).
