Simple Steps to Install a 30 Amp Breaker: A Guide to Electrical Wiring
Here is a look at what to do to complete this task.
Tools You Need for the Job
Aside from the obvious requirement of having a replacement ready to install, you also need to prepare properly so that you can do the job safely and competently.
One of your first tasks is to check that this type of breaker is compatible and approved for use in the electric panel that you have on your property.
A good set of screwdrivers and a pair of pliers is needed. You should also have a multimeter. This will allow you to check that the power supply is off and also test whether the new circuit breaker is working.
Make sure you are wearing a pair of rubber-soled shoes. This will provide protection if you are subjected to an electrical shock.
Turn the Power Supply Off
The main power switch is usually clearly identified as the main switch on the panel. It might also say “service disconnect”. Once you have located this switch, turn it to the off position and check that the power supply is disabled.
Locate the 30 amp circuit breaker you are replacing on the panel. It is usually at the top or the bottom of the row, as it is the biggest amp value.
Use your chosen screwdriver to remove the fixing screws and gently pull the metal frame away from the panel.
Check the Power Supply is Definitely Off
This is the point where you should use your multimeter to confirm that the power supply is definitely off before you carry out any further work.
Set the multimeter to VOLTS AC and test the panel by touching one prong to the neutral and the other probe to the screw terminal on the circuit breaker. A reading of 120 volts or above is an indication that there is still power to the breaker and it needs to be disconnected if you get this reading.
Put the Breaker in Position
If you are adding a new circuit breaker to the existing circuit position it next to the other 30 amp breaker. There might be a knockout plate to remove if there is a spare slot you can use. Alternatively, just use the existing slot if you are replacing your existing breaker.
Turn the Breaker Off
Turn the breaker handle so that it is in the OFF position before you fix it to the panel.
Press firmly until you are sure that the breaker has clicked into place and is secure.
Wiring the Breaker
You will need a good quality pair of pliers to ensure that you can strip the insulation sleeve from the hot and neutral wires. Remove about half an inch of the sleeving.
Insert the wires into the correct terminal location and tighten the screws until you are sure they are nicely secure.
Check Everything Works
Once you are happy that you have correctly and successfully installed your new breaker using the multimeter you can turn on the main power supply and you are good to go.
As long as you have safety in mind at all times, you should find that installing a 30 amp breaker will be a DIY task you can perform with ease.
