How many watt generator do you need to run a house? (With load calculation)

Size is really important when it comes to generators for running house appliances.  When you undersize a generator, you will not be in a position to power your appliances. When you oversize the generator, you will just be wasting money!

How Many Watt Generator Do You Need To Run A House

What Type of Equipment will the generator run?

First, you need to come up with a list of equipment which you will be powering and all their total wattage.

It is this total wattage that will tell you what amount of electrical power are needed by the equipment. After knowing this, you can now proceed to working out the minimum amount of electrical input required from the generator.  Wattage information is always available in the silver nameplate of the equipment or the manufacturers guide.

NB. There are electrical appliances that have a different starting wattage and running wattage. This is because they do require more energy to start them up than it does to keep their motor running.

Converting kW to kVA

When you add the maximum amount of wattage for your equipment, you will get the total power required in kilowatts (kW). Kilowatts are the real power that will be needed by the load to give out a working input which will be enough.

Generators are usually rated using kilovolt amperes (kVA).  The KVA refers to the apparent power measure. It will inform you the total power amount you will be using in the system.

There are tools that have power requirements stated in amperes:

Watts and Amperes are completely different units that are used in calculating the total consumed power.

When you know the number of amps your appliance or tools needs to run, you can always calculate the wattage requirement using this formula:

Wattage = Amps* 120

Example 1:

When you are in need of powering a MIG welder with 120V and 70 Amp

70 AMPS * 120V = 8400 W

This simply means that you will require a generator having at a minimum 8,400 running watts to successfully run a MIG welder.

Example 2:

Let’s say you have a refrigerator that uses 7.1 amps and is operating at 115 Volt AC power

The total consumption of power in watts is 7.10 Amps * 115V = 816 watts.

When you know the wattage and you are interested in knowing the amperage of the appliances, you can use this formula

Amps= Wattage/ Voltage

Example 3:

Let say you have some appliances that you need to run using the generator, this example shows us how to go about it.

Appliance
Starting Wattage
Running Wattage 
2 ton central ac
8750
3800
Clothes dryer
6750
5400
Washing machine
1200
1200
Electric water heater
4500
4500
Freezer/ Refrigerator
2900
5400
Total wattage
24100
15600

In the case above, you will require a generator with a minimum of 25kW since all the appliances that will be using the generator have 24,100W as the starting wattage.

Define the running requirements

You need to know if the generator will just be a standby measure or it will be the main source of power.

It is advisable never to operate a generator at a maximum capacity exceeding 30 minutes. In case you will be using the generator as the main source of power supply, it is advisable that you size for 70% to 80% capacity.

You can always leave a 20% to 30% safety margin as a safety margin.

How to Hook Up Gas Generator to House?

There are two main methods you can always use to connect gas generator to your house. The first method is connecting the appliances directly to the generator while the second method is connecting the generator to the electrical grid of your house.

When you plug the generator to the wall socket directly in what is referred to as back feeding. However, this method can cause lots of damage to the electrical wiring of the house or even at times can lead to fire outbreak. Backfeeding is illegal since it can electrocute the technician working on the lines.

Using Transfer Switch to Connect the Generator

Transfer switch refers to an electrical control gadget which you can install directly together with the circuit breaker box at your home. The main role of this transfer switch is to help switch the electrical grid off of your home of the electrical utility grid onto the gas generator.

You can also use the transfer switch to help in making management of power quite easy. This transfer switch will act like the circuit breaker in your home. This will make it possible for you to load different outlets, rooms and appliances. It is also possible to control the outlets that are on a particular sub breaker when using the transfer switch.

In order to effectively control the wattage amount that is being drawn from the generator, all you will have to do is turn one of the breakers on and off. With this, you will be able to keep your house connected to the generator.  You will only draw power whenever you are in need of using a specific appliance. This makes it possible for one to use smaller gas generators to help in powering up homes.

Installing Transfer Switch

Experienced electricians are the ones who are tasked with transfer switch installation as it involves moving wires that enter the circuit breaker board of your house. However, it is also possible for homeowners to carry out installation of transfer switch only if they have experience in electrical wiring and use of transfer switches.

During installation of a transfer switch, the most important step is to identify the circuit which is coming from the main board circuit breaker and move it to the circuit of the transfer switch.  The level of determination will be determined by the type of appliances you are interested in running during the power outage period and the generator size. In case you are using a universal transfer switch, you will have to program it in the different appliance priority levels.

Connecting the Generator

For you to successfully connect the generator, you will need to get a specialized generator cord that will help you connect the transfer switch to the generator. The cord is usually plugged into the outlet on the generator and onto the transfer switch inlet. 

It is important to always be prepared for an outage way ahead of time. You can achieve this when you leave the generator always connected to the transfer switch.

It is also advisable that you always keep the gas generator cord located with either the transfer switch or the generator as you will be moving around in the dark in case of power outage. Ensure that you do flip the main breaker up to enable it draw power from the generator inlet instead of from the electrical utility grid before you start up the generator.  You also need to ensure that all breakers found on the transfer switch are off especially when using a manual transfer switch.

Ensure that the generator is situated in a well-ventilated are or outside before you start it up.

How to Choose the Best Gas Generator for Home Use?

The wide variety of gas generators in the market for home use has made it quite challenging for buyers to identify which suits them best. In this section, we will be looking at some of the important factors one need to consider when in the market for the best gas generator.

Not all the generators in the market are equal; there are some which are made for use only for a few hours.

  • What size generator do I need for a 250 amp welder?

It is never that easy to determine the exact size of a generator to run   a welding machine. However, for a 250 am welder you can go for a generator with a minimum size of 13kva. The most ideal generator size you can be sure of is the 15+ kva.
