Why Is There No Main Breaker In Service Panel? (Solved)

It’s commonly assumed to check the main breaker in a service panel when there is an electrical issue including a lost neutral.

When this occurs, the first reaction is to go to the service panel and check the main breaker.

However, what if there is no main breaker in the service panel?

In older homes, it’s common for there to be no main breaker in the service panel. In situations such as this, it’s best to consult with an electrician to analyze the electrical circuit and pinpoint the root cause.

All new homes will come with the main breaker as it is part of modern building codes around the world.

However, if it is an aging home, it is likely the main breaker was never set up.

You will also have to account for the type of setting you’re in. For example, a person that is residing in an apartment building will never have access to the main breaker to the circuit. This would mean one person has access to the entire property’s power.

Instead, it will be sourced in a different part of the building and is controlled by one supervising party.

This article will explain what you should do when there is no main breaker in the service panel.
