When it comes to choosing a portable generator for your construction site, it is important to keep in mind that not all job sites carry the same power requirements. Power needs and requirements vary from one location to another, it’s important to rent generators that will accommodate different needs on a project-by-project basis.

First step is to calculate power requirements of commonly used equipment. Assess what equipment the generator needs to power, be sure to consider not only the required power needs to run, but also add in a buffer. Some equipment requires more power to start, than to run. Most importantly, a portable commercial generator can help power key equipment, such as saws, drills, pumps, grinders, welders, compressors, and even help charge battery packs for battery powered equipment. Here we are providing power for floor grinding operations.
