I'm looking at putting a Power Inlet Panel (PIP) on a building so it can be powered with a portable generator during an outage. The system is 120/208 and the PIP will be powered by a 60KW portable.
The portable will be delivered and set up by a company that rents, delivers, fuels and sets up the temporary connecting cables between the PIP and the generator.
My question is how do they deal with phase rotation? Other than looking for a three phase motor and bumping it to see if they guess right, is there a better way? Are these guys just used to doing this? When I do a cutover I use my rotation meter and make sure I get it to be the same but with no normal power available that won't work.
