hi all - I have a new 8000 watt portable generator that I am going to use for power outages. I have a transfer switch and all the wiring done. I plan on building a small shed to enclose the generator in in my backyard. The shed will be about 5 feet long, 4 feet wide and 4 feet high. I am planning on putting two four inch holes on each side of the shed for airflow and I am also going to install a fan through a larger hole in the rear of the shed for airflow.
My (stupid) question is, do I want the fan to pull air in from the outside or to exhaust the hot air from the inside out?
