One of the most common things we hear from homeowners is this:
“I need more power to this circuit. I will just put a bigger breaker in.”
We understand the thought process. If something keeps tripping, it feels like the breaker size is the problem. In most cases, it is not.
Upgrading a breaker without upgrading the wiring behind it is unsafe and can create a serious fire risk.
What a Breaker Actually Does
A breaker is not there to protect your appliance. It protects the wire inside your walls.
Every wire is rated to handle a certain amount of electrical current. The breaker is sized to match that wire. If too much current flows, the breaker trips before the wire overheats.
When someone installs a larger breaker on the same wire, they remove that protection. More power is now allowed to flow through wiring that was never designed to handle it.
That is where problems begin.
Why a Bigger Breaker Does Not Create More Capacity
If a circuit is tripping, it usually means one of two things:
• The load is too high for that circuit
• There is a wiring issue
Simply installing a larger breaker does not increase the capacity of the wiring. It only increases the amount of current allowed before it trips.
We often say that you cannot just put a bigger breaker in there to get more power. The real solution may involve:
• Running a new dedicated circuit
• Upgrading the wire size
• Adding a subpanel
• Upgrading the main panel
Each situation is different, but the answer is never just a bigger breaker.
Other Common Assumptions We See
We also hear things like:
“I will just add this appliance to the existing circuit.”
Or
“It worked before, so it must be fine.”
Homes today use more electricity than they did years ago. Adding EV chargers, larger kitchen appliances, and home offices increases demand. Older panels and wiring were not designed for that load.
Electrical systems need to be evaluated as a whole.
What To Do Instead
If you need more power in a certain area of your home, the safe approach is simple.
Have the circuit evaluated.
We check the wire size, breaker size, panel capacity, and total load. From there, we recommend the proper upgrade. That may mean a new circuit or a panel upgrade, but it will be done safely and up to code.
