I was asked by my best friend to look at a proposed portable E-gen set-up for a 2 year old county maint. garage. This garage has a single phae 400a main brkr panel w/42 ckts. While looking at the "set-up", I saw they had all ready installed a 100a pin recept. outside, back wired into a Ronco manual 2p transfer sw. This manual Xfr fed into the single phase 400a main panel. I then began to point out a miriad of problems to him. Please correct me if my concerns are not warranted. 1. This is a manual XFR-SW, no automatic way of POCO isolation, unless you knew to manually open the 400a main brkr.( I assume the E-pwr was wired to the load side of main brkr ) 2. No LOTO of any kind on the XFR-SW or Main, to prevent the obvious. ( as it sits now, if the XFR-SW was thrown,it would pass the entire main, to the pins of E-GEN recept. ) 3. No posted SOP for E-gen procedures. No labeling of any kind, nothing listed in the panel directory for what the E-PWR feeds, (assume the entire panel) 4. Should'nt there be a brkr on the 100a E-pwr wiring, supplying the main panel? (the conduit run is about 5' and these conductors are not protected, if a short would occur). I have not seen the E-GEN yet. But it is only 20kw, 50a. This all-ready long enough, but I want to help my friend.... I told him he should contact the original EC, for any other inquiries/shortcomings. I feel the EC was in this project for quick government $$$. This facility was overbuilt, has room to expand, no extra ordinary life safety demands/requirements other than it being a county/gov't bldg. The load demands of this facility are really low. I think the well pump & door operators are the largest loads, outside a welding recept. Thank you for reading..... PleaseTell me that the sky is not falling
