Installed the temporary electrical panel for power during construction. I rented a rock saw and cut through 24 inches of rock to create a 130 foot trench to the home site. We used 250MCM aluminum cable run in 2.5 inch pipe from the Main Panel to the temporary power panel. There is also an external 4 AWG copper ground connecting the Main Panel to the temporary panel.

Main Panel shortly after installation.

Side shot showing the ground wires. Note the ground rod was cut into 2 - 4ft. pieces. After trying multiple locations, we found that the rock was just too dense. Even driving it in diagonally proved impossible. The power utility allowed us to finally drive 2 separate 4 ft. deep, but bonded together stakes.

Back of the panel. I created a plywood box to protect the extra wire needed to complete the run to the house later.

Back of the temporary panel. The wires are fed into the temporary panel on the front. Note the ground wire that also runs through the trench to the power panel. I wanted to ensure a really GOOD ground.

Front of the temporary panel. There are 2 - 120v 20A circuits, 1 - 120v 30A plug and 1 - 240v 50A plug.

The back of the panel is screwed on to protect the cables inside.

All 120v circuits are GFCI protected. ($$$)
