You just need some pre-planning, a little knowledge and some days of your time.
Where to begin?
Thinking about the very first step to wiring your shed will save a lot of money and time. The first thing to think about is to decide what is your outdoor storage is going to be used for. The electrical parameters for a shed differ from those for a workshop. If it is going to be a storage shed, an easy DIY project in a weekend is the solution. If you are going to use your shed as a workshop, including a welder, power devices, air compressor or similar tools, a little more planning is needed.
What devices to use?
One electrical circuit can operate many amps. So, if you want to run appliances or equipment requiring lots of amps, you need to provide your shed with enough circuits to operate the load.
Knowing what are you going to do in your workshop will help you in choosing the type of wiring and outlets and deciding on the number of circuits you need to install as well. When you are up with all these things, it’s high time to consult with an electrician to ensure the circuits are strong enough.
Can the house panel handle the extra load?
Most contemporary homes are provided with a 200-amp service, which supplies enough current to run your property and the extra load of a storage shed with lights. But, if you want to provide your shed with some equipment, or some type of heating and cooling, you will need to make sure there are enough amps to cover it. In this case, a sub panel may require wiring.
How to get the electric power from the house to the shed?
For a single circuit using an extension cord is the best way to run power. Usually, homes built after 1980 are provided with GFI-protected outdoor outlets what is completely safe to have a single outlet in an outdoor shed connected to the house through the exterior-rated extension cord.
If you want to create a workshop and provide it with lots of circuits, the best way to run power is to hide the lines in the ground.
How long will it take to execute the project?
The planning stage takes the most time. On this stage do not forget to consult with an electrician about the equipment you are going to utilize in your shed to ensure your circuits are strong enough. As soon as you finish with planning, you will be able to complete with the wiring in half of a day. To wire a workshop may take some days.
