Im feeling a little bit humbled and stressed about an upcoming job that im responsible for.
Im a second year journeyman with a fairly strong background of mechanics and electrical prior to becoming a jw at the age of 34 so I tend to think fairly highly of myself yet im up stressing on a friday night before I start a job on monday night that is out of my comfort zone.
I tend to be an overthinker and worrier but need some advice.
Starting a refridgeration swap for a retail store. Was bid to reuse existing and basically a direct swap of freezer cases at a walmart store.
Ive done refrideration but never quite like this, they are fed underground to a pit and each section of casing has 3 circuits, Im doing this project solo and we are planning on taking down 7 cases every other night and installing new cases the night after we demo a section.
My first major concern is that I need to 1 go over the prints with a fine tooth comb and make a list thats easy to follow on what circuits are being used.
Then more importantly if we are resuing existing circuitry and OCPD, I highly doubt its GFCI protected. Shouldnt everthing on these cases be GFCI protected.
Furthermore, peeking at the panels in the cooling tower it shows that everything is currently 120v and the new coolers are 208v, there is some spares in the panel but I would imagine I will run out of room and need a sub panel in a crowded cooling tower. What if the circuits end up being 3 phase multis!?? I wont be able to re-identify a nuetral to a phase for 2 of the circuits.
Does anyone have any experience or advice on this? Im sure ill be fine and figure it out. Im just up late stressing on a friday night about a job on monday which I promised myself I would never do.
