Temporary power is a short-term or nonpermanent power structure. It's a safe and reliable electricity supply for tools, lights and facilities for the duration of a construction project. The temporary electrical infrastructure is removed when the project is complete.

Power systems have various components, including distribution panels, transformers, transmission units, breakers and safety devices, cables and wires, nonpermanent power poles, and a power source.

Various power sources can supply temporary power, including:

• Generators: Portable and containerized generators come in various sizes and can offer a safe power supply on numerous sites. Select between gasoline, diesel and natural gas generators for your needs. These generators are easy to transport and can come in containers to enhance safety and security. Generators might work best for short-term and small-scale projects as you'll need to refuel them, which can become costly for large-scale jobs.
• Spider boxes: A spider or temporary box is a unit or enclosure for distributing power safely and efficiently. It uses a power source and distributes electricity via connected cables. You can transport these units and use them on various sites.
• Solar panels: Panels that power machinery and facilities on construction sites using renewable energy. Solar panels can be portable and provide a sustainable power solution.
• Power poles: A power supply company can install power poles on your construction site and power large projects. These poles require permits and professional installation and can work well for projects running over a long duration.

Steps like obtaining permits, professional design and layout and local authority inspections are vital when setting up temporary power for your construction site. These procedures ensure your temporary construction site power source works properly and provides a safe working environment for you and your team.

Consider the following when setting up temporary power on your site:

1. Evaluate Power Requirements

Think about your project objectives and timeline, and identify the equipment and facilities you'll use and when you'll need to power them in the day. When you understand your project requirements, you can ask suitable questions and plans and coordinate effectively with your temporary power supply company.

2. Local Authority Permits

Understand local laws and regulations for installing a temporary power supply. If you need permits, contact your local authorities, utility company or city office for more information. Getting your permits and following the appropriate steps is required before installing your temporary power supply.

3. Work With Power Supply Companies

Research local power supply companies and detail your requirements like project size, duration and equipment quantities. High-quality and reputable brands can offer valuable, safe and reliable services.

Consider companies that are available in case of emergencies. Power supply companies will also ask you various questions to understand your project requirements, such as:

• How much power do you need?
• Do you have design or architectural site plans?
• Can we schedule a site visit?

Have this information in mind so you can work together to determine the best fit for your needs.

4. Site Visit and Planning

Your power supply company will visit your worksite and plan and design the power distribution system layout. During this visit, your power provider might ask questions like:

• When does the project begin?
• How long will the job run?
• What equipment needs temporary powering?
• What are you constructing or working on?
• Do you have special equipment like man-lifts and two cranes that need temporary powering?
• Which site areas require power?
• Are there utility sources available?

Again, keeping the answers to these questions front of mind will lead to the most beneficial power supply setup for your power supply.

5. Design Proposal and Quote

Your power supply company will coordinate and plan with you to design a suitable site layout for your power distribution system setup. They can also highlight safety features in their plans and layout. After creating the layout, your power provider will offer a proposal and various quotes. Work with them to decide on the best arrangement for your budget and needs, such as comparing new or used generator options.

6. Site Layout Verification

Your electricity supply company will conduct a second site visit to verify everything is in place and there are no changes. They will also confirm and handle various requirements like inspections, permit processing and utility fee management.

7. Safety Training

Conduct training to ensure all teams understand the safety requirements for working with a temporary power supply. You can also do a checklist and tick off various safety protocols to ensure you have the proper processes in place:

• Clear vehicle and equipment traffic around electrical infrastructure
• Ensure power equipment is secure and adequately grounded
• Inspect cords, wires and cables and ensure they are safe for use
• Comply with OSHA temporary power requirements

8. Temporary Power Installation

Your electrical provider's experienced and knowledgeable technicians will install your power system on your construction site. You and your employees should follow the supplier's rules, timelines and requests during installation to ensure everything goes smoothly.

9. Inspections and Maintenance

The local authority who gave your permits will inspect your infrastructure after installation. They will assess your setup, ensuring it complies with local electrical and safety codes.

The utility company can only connect your transformer and turn on your power if you pass your inspection. Once you pass these evaluations, you can use your electrical power system and begin your project. Your temporary power provider company will conduct periodic maintenance checks during your project to ensure everything runs smoothly.

10. Switch to a Permanent Power Supply

Your temporary power supply company will disconnect your infrastructure once your permanent supply is up and running and you've switched to the primary power source.

Buying a used generator for temporary power can offer numerous benefits.

• Availability: Buying a used generator can have short lead times, meaning you get your power supply on time for your project start date.
• Reliability and safety: The dealer can offer certified used generators, meaning these units undergo inspections and tests, providing premium quality temporary power sources at cost-effective prices.
• Versatility: Equipment dealers keep a vast inventory to match your project objectives, whether you need a stationary or portable generator.
• Affordability: You can effectively power your worksite, equipment, facilities and lights at lower prices.
