Building a temporary power pole for underground service involves creating a safe and functional electrical setup that can provide power to a construction site or other temporary location. This guide will help you build a basic temporary power pole for underground service, but it’s important to consult local electrical codes and work with a licensed electrician to ensure safety and compliance with regulations.
Materials and Tools Needed:
- Pressure-treated wooden post (6×6 inches)
- Meter socket with a disconnect
- Breaker panel or load center
- Ground rod and grounding system
- Conduit and fittings
- Electrical wires (copper)
- Weatherproof boxes and covers
- Receptacles and switches
- Wire connectors
- Concrete and rebar for footing
- Shovel, drill, saw, level, measuring tape, and other hand tools
Steps:
- Determine Location and Install Post:
- Select a suitable location for the temporary power pole, considering proximity to the construction site and underground service entry.
- Dig a hole and set the pressure-treated wooden post as the main support for the power pole. Use concrete and rebar to secure it in place and ensure stability.
- Install Meter Socket and Disconnect:
- Attach the meter socket with a disconnect near the top of the post. The meter socket will measure the electrical usage, and the disconnect allows for safe power shut-off.
- Install Breaker Panel or Load Center:
- Below the meter socket, install a breaker panel or load center. This is where the circuit breakers for the power distribution will be housed.
- Grounding System:
- Drive a ground rod into the ground near the power pole and connect it to the grounding lug on the meter socket. This provides a proper grounding system to ensure safety.
- Conduit Installation:
- Run conduit from the meter socket to the breaker panel and underground to the service entry location. Use appropriate fittings and straps to secure the conduit.
- Install Weatherproof Boxes and Receptacles:
- Attach weatherproof boxes at strategic locations on the power pole for receptacles and switches. Ensure they are securely fastened and weatherproof.
- Wiring:
- Run appropriate electrical wires through the conduit, connecting them to the meter socket, breaker panel, and weatherproof boxes as needed. Use wire connectors to secure connections.
- Connect Receptacles and Switches:
- Install receptacles and switches in the weatherproof boxes and connect them to the wiring following electrical codes and safety guidelines.
- Inspect and Test:
- Have a licensed electrician inspect the temporary power pole to ensure compliance with local codes and regulations.
- Test the system to ensure proper functionality and safety.
- Energize the System:
- Once the system is approved and tested, energize it, and ensure that power is properly distributed to the intended areas.
Always prioritize safety and compliance with electrical codes and regulations when building any electrical infrastructure. It’s highly recommended to consult a licensed electrician for guidance and assistance throughout the installation process.
