Common Questions About Industrial Generators
How long can an industrial generator run without overheating?
Industrial generators are specifically designed to run for days on end and will do so without any issues if they are maintained properly.
That said, the actual running time will depend on the capacity of the generator’s fuel tank and the amount of load being put on it.
How do I determine the size of the industrial generator I need for my business?
So, you start by listing down all the essential machinery you want to keep running during a blackout and adding up their wattages. A good practice is to add 25% to this figure to account for any power surges or if you need to run additional machines.
The added benefit of doing so is that your generator will not be running 100% all the time, which will put less load on it and improve its fuel economy.
I already own a generator; can I buy a second one and connect it to double the output?
The short answer is yes; industrial generators can be connected in parallel to combine their power outputs. If the two units are exactly the same, then it is a straightforward process.
However, attempting to connect two dis-similar generators in parallel is a complex endeavor as they need to be synchronized and it is an exercise best left to the professionals.
What do the terms reconnectable and non-reconnectable mean in the context of industrial generators?
The terms reconnectable and non-reconnectable refer to the ability to alter the connections of an industrial generator to vary its output voltage. Reconnectable Generators typically have either 10 or 12 leads that can be reconfigured to alter the output voltage and to produce a single or three-phase output.
A non-reconnectable industrial generator has a fixed output voltage and phase.
What does an EPA rating mean for Industrial Generators?
The EPA rating on a generator signifies what emission standard it meets as set by the Environmental Protection Agency (EPA). The higher the tier, the more fuel-efficient and environmentally friendly a generator is.
That said, the EPA rating will also differ based on the size of the generator, its year of manufacture, and what type of generator it is.
What are the safety precautions to keep in mind when operating an industrial generator?
Industrial Generators are complex machines that need to be used with the utmost caution to prevent any damage to them or the people around them. Here are a few:
- Stick to the maintenance schedule for the generator.
- Never operate an industrial generator in an enclosed space.
- Never store fuel in the vicinity of the generator.
- Never touch a generator when it’s running without protective clothing on, and always ensure that the generator is grounded.
