A contractor must have a generator to run the power tools and electronics on a construction site. Most of the construction sites don’t have electricity, so without a generator, no one can do any sort of work that needs power.
There are various benefits of using portable generators at the construction sites. They are easy to move from one point to another point. You can also run any power tool with ease.
So, in this article, we are going to highlight those generators that you can use at the construction sites. Go through these units to select one that meets your needs.

Before going to buy a generator for the construction site, there are various things that you have to keep in mind to get the right unit and to meet your needs.
How much power your generator should be? It depends on the tools and appliances you are going to run at your construction site.
There are some power tools that require more starting watts than running watts, so you have to keep this thing in mind. Always try to select a generator that can produce more starting and running power than what you need.
Make a list of those things that you mostly need to run at the construction site, add their starting and running watts, get the total required power, and then buy a generator that can generate more power than you require.
You should also keep this in mind that the altitude of the job site where you are going to use the generator can also affect the generator’s power. If you are going to work in high altitude areas, then you must know that engines lose 3% of their power for every 1000 feet of altitude.
Always look for a generator with a big fuel tank so that you can run your unit for a longer period without refueling it. Also, you should focus on the material of the tank. It must be made up of metal.
It is always beneficial to have a generator that can run for a whole shift without a need to refuel it. Refueling in between the working hours may decrease productivity. So, make sure you are buying a fuel-efficient generator.
Also, fuel efficiency depends on the fuel you are using. You can use diesel or gasoline because these two can give good runtime as compared to propane.
Before buying a generator, make sure you know the local laws and regulations. This will help you out in selecting the right generator with the right operational sound.
Some of the states and areas limit the noise level, so your generator must not be louder than that limited sound rating.
You can ask about the rules and regulations from a local professional dealer.
It is always necessary to have a portable generator at the construction site so that you can easily move it from one place to another.
Ensure the generator you are buying has big, durable wheels and comfortable handles to pull it easily.
Never buy a generator that has small wheels because they might not run well on all the surfaces.
