Lucky I have a NZ electrical licence........have not worked in that industry for years.That is the reason I wish growers were just required to have electricians come certify their rooms!
As far as the fan I might have an idea for you. If heat becomes an issue for you then pushing or pulling air from outside the tent through the light then outside the tent again will help combat that for you. That really will be controlled by what wattage bulb you use and how much heat it is generating.
My fan will be bringing fresh air from outside, dumping outside during warmer days, then switch to your suggestion during colder months to dump the warmer vented air into the mass of the room to stabilize that a little from cooling.
So - mucking around in the shed for the last hour - and this is what I have came up with -
Nicely calibrated too.
One to control mother room, 1 for the clone and the last goes to the flowering room. wired with 1.5mm, short distance - easily capable of carrying easy 20amps on 240v, no worries on heating mode being series wired .
