Question 1

What is included in a temporary power rental system?

Accepted Answer

A complete temporary power system has three parts: a rental generator sized to your actual load, the distribution equipment that carries power where it is needed, and fuel storage to keep it running. Distribution includes transformers, transfer switches, spider boxes, and feeder cable. Mobile Air & Power Rentals supplies all three components from a single fleet, so the generator, distribution equipment, and accessories are specified to work together rather than sourced separately from multiple vendors.

Question 2

How do I get temporary power to a construction jobsite?

Accepted Answer

Temporary jobsite power starts with a load assessment covering total connected load, voltage and phase, and every point on the site where power has to reach. From there the system is built out with a generator, distribution boxes, and feeder cable run to each work area. Mobile Air's Engineered Solutions process handles that assessment first, evaluating power requirements, site constraints, and load demands before equipment is delivered, so the system matches the site rather than being oversized as a precaution.

Question 3

What power accessories do I need besides the generator?

Accepted Answer

The accessories you need depend on how power has to move through your site. Transformers step voltage up or down to match your equipment, transfer switches move load between utility power and the generator, spider boxes split one high-amperage feed into multiple usable outlets, feeder cable connects the system, and fuel tanks extend run time beyond the onboard tank. Each of these power accessories is available from Mobile Air as part of a designed temporary power system or as a standalone rental.

Question 4

What is a spider box, and when do I need one?

Accepted Answer

A spider box is a portable power distribution box that takes a single high-amperage feed from the generator and splits it into multiple standard outlets. A spider box is typically needed any time several crews, tools, or pieces of equipment have to draw power from one source, which covers most construction and event setups. Mobile Air rents cam-type three-phase spider boxes individually or as part of a complete temporary power package.

Question 5

Can a rental generator connect to my building's existing electrical system?

Accepted Answer

Yes. Rental generators can be integrated into a building's wiring, typically through a transfer switch, so load can be moved between utility power and the generator without an uncontrolled shutdown of sensitive equipment. The alternative is a standalone distribution setup that bypasses the building entirely. Which approach fits depends on your service configuration and what has to stay energized, which is why a site assessment comes before the equipment recommendation.

Question 6

What is a load bank and why would I rent one?

Accepted Answer

A load bank applies a controlled artificial electrical load so a system can be tested under realistic operating conditions rather than assumed to be ready. Two common uses are commissioning or verifying an existing electrical system, and exercising a standby generator that sits idle most of the year so it performs when it is eventually needed. Mobile Air rents load banks alongside its generator and distribution fleet.

Question 7

How much does temporary power cost to rent?

Accepted Answer

Temporary power is quoted per project because the cost drivers vary widely, including the kW capacity required, rental duration, voltage and phase, the amount of distribution equipment and cable the site needs, delivery distance, fuel, and whether installation and on-site management are included. A load assessment produces an accurate quote faster than a generic price list. If you want a rough starting point first, the amp chart converts equipment amperage into the capacity range you are likely to need. For occasional or seasonal requirements, renting also avoids the capital investment, maintenance, and storage costs associated with owning a unit.

Question 8

How fast can you deliver emergency power?

Accepted Answer

Mobile Air & Power Rentals provides 24/7 emergency response from branch locations across six regions: Northeast, Southeast, Midwest, Great Lakes, Gulf, and Western. Equipment is dispatched from a nearby branch location rather than shipped across the country, which matters during a regional outage event when availability is limited. Call 888-305-3038 to reach the 24/7 line and confirm response time for your location.

Question 9

Do you rent temporary power to homeowners?

Accepted Answer

No. Mobile Air & Power Rentals serves commercial, industrial, institutional, and event customers rather than residential ones. Typical customers include facility managers, general contractors, plant engineers, healthcare and data center operators, and event producers. Homeowners looking for a portable generator should contact a consumer equipment rental provider.

Question 10

Why rent temporary power from Mobile Air & Power Rentals instead of assembling it from multiple vendors?

Accepted Answer

The main advantage is coordination. Mobile Air's Engineered Solutions process assesses your power requirements, site constraints, and load demands, then supplies the generator, distribution equipment, and accessories as one integrated system. Delivery, setup, and on-site management are handled by the same team, giving you a single point of accountability rather than coordinating a generator supplier, an electrical contractor, and a cable vendor separately.
