Before you can go shopping for your new generator, you need to make sure that you know what size you will need when the power goes out. 

Having a generator that is too small means that you won’t be able to run all of the appliances that you want to, and one that is too large is just a waste of money unless you intend to expand in the future.

First you have to write down all of the appliances that you will want to be able to run during a power outage. 

Once you have done this, you can determine the wattage that they will all use and then add this information up and then multiply it by 1.5.

Multiplying it by 1.5 allows for the extra amount of power that you will need to start each appliance, as they take more to start than they do to run. 

With the total wattage that you will need, it’s significantly easier to decide how large your new generator needs to be.

Benefits of Having a Portable Diesel Generator

Many people only think of using their generator when they lose power to their home, but you can get far more use from a portable generator. 

Not only are they ideal when you are faced with a loss of power, but you can easily take your generator with you on the road when traveling. 

If you love to camp, whether in a tent or in an RV, having a portable generator will ensure that you have the power that you need when away from home. 

What to Look For

Some portable generators come with an auto-idle control feature. 

This will actually cause the engine to idle down when you are not using as much power. 

This allows your generator to operate more efficiently while extending the run time. Another feature to consider is an electric start. 

A push button start is significantly easier than trying to start a generator with a pull cord. 

If it is within your budget, I highly recommend opting for a model with an electric start.

How to Best Use Your New Portable Diesel Generator

Before starting your new generator, I recommend reading the owner’s manual so you understand your particular models functions and maintenance needs.  

Never try to plug your generator into an outlet in your home to feed electricity from the generator to your whole house. 

Not only does this increase the chance of an electrical fire, it can also damage any home that is run by the same transformer. 

Even worse, doing this can kill any worker who is currently servicing the power lines. 

Portable generators aren’t the same as whole-house generators.

When you want to turn off your generator, first disconnect or turn off any appliances plugged into it. 

You will then need to follow the directions in the owner’s manual on how to turn the generator off. Wait until it is cool to move and store it.

Safety Considerations

To be safe when you are running a portable diesel generator, you have to make sure that you have a carbon monoxide detector in your home. 

Make sure that you always operate your portable generator outside and away from your home. 

While it can be tempting to use your portable generator in a crawl space, basement, or outside building, this is not safe. You have to make sure that your generator is outside and away from the home.

You also have to make sure that you use an extension cord that is rated to handle the wattage for your generator. 

It needs to be at least 14 gauge. 

First, start your generator, then plug in the extension cords. Never plug in more appliances than you have planned for, as this can damage the motors on your appliances, trip the breaker, or even blow a generator fuse.
