A good contractor always ensures the power supply, right tools, and other equipment to the crews for perfect construction work. Among all, the power supply is the most vital part for sure since you cannot run other tools without it. Unfortunately, you will not get the right power supply near the construction site all the time. You will need a generator to cover up the power.

However, for construction, you need a small, compact, and portable yet powerful generator. You will get all of those in the best portable generator for construction. It is a great investment you can make to ensure your crews that they have the power supply needed for work all the time. 

What size generator do I need for a construction site?

For construction work, you have to ensure the power supply for multiple pieces of equipment. Most of the site work requires powering an air compressor, circular saw, hand drill, battery charger, and others you purchase for your project. If you calculate the power supply needed, it will be around 6,000 to 9,000 watts.

A medium-size generator is capable of providing that power to your site project. However, if you have tools and equipment with less power, you may get your job done with a small, portable generator too. That means it completely depends on what types of equipment you are using for your construction project.

How Portable Generators Work for Your Construction Sites?

In the construction site, you need to run tools such as air compressors, battery chargers, hand drills, chain saws, circular saws, and others depending on the projects. Since most of the construction projects are done in the remote area where the electricity supply is inadequate, you may not be able to get the power you need. Also, you will not get a continuous power supply from electricity as well. 

Besides, since it is not a permanent project, you cannot install a permanent generator to provide you the power. A portable generator comes here to help with its portability. Also, it comes with outlets with different AMPs and voltages that let you use different power tools at once. It can either provide continuous power supply or deliver power during the power outage. 

Frequently Asked Questions

Having questions about a topic will help you know more. If you have questions about the portable generator, you should see the questions below. You may find your answer there.

Do you really need to ground a portable generator?

It depends on the separately derived system of the generator. If your portable generator has this system, you will need to ground it and if there is no such system, you do not need to ground your generator at all.

Which power source is used on a construction site?

Since construction sites require a continuous supply of power, most of the time oil or gas-based generator power sources are used. Gas and oil are easy to transport in remote areas or others.

Where should I place my portable generator?

You should always place your portable generator at least 20 feet away from the working area. Also, make sure the wind is against the generator so that the hot exhaust does not come towards the workers. 

Do you need a transfer switch for a portable generator?

Yes, it is mandatory to install a transfer switch if you want to use a portable generator. It is not safe to use a portable generator without a transfer switch and also, it limits the power of the generator as well.

How much does it cost to install a transfer switch for a portable generator?

It depends on the labor cost you need to install the switch. In general, you can complete installing the transfer switch within $500 to $900 including your labor cost.

Final Thought

Most of the portable generators offer minimum noise with adequate power. However, some generators lack high run time where some have a lack of mobility. A good generator will provide you good power supply, excellent run time to complete the project, and minimum noise. At the same time, it should offer enough portability with maximum convenience. 

We have reviewed some such generators above. However, if you are still confused about choosing the best portable generator for construction, I will suggest you go for the Durostar Portable Generator. It has an 18 HP 440cc engine that is good enough to power up your construction tools.
