What to Do When Your Circuit Breaker Keeps Tripping

A circuit breaker that keeps tripping is more than just annoying—it's a warning sign that something in your electrical system needs attention. Here's how to diagnose and fix the problem safely.

Understanding Circuit Breakers

Circuit breakers are safety devices designed to protect your home from electrical fires. When they detect an overload, short circuit, or ground fault, they automatically shut off power to that circuit.

Why Breakers Trip

Overloaded circuit (most common)
Short circuit (serious)
Ground fault (potentially dangerous)
Faulty breaker (age-related)
Damaged appliance or wiring

Safety First! ⚠️

Before touching any electrical component:

Never work on a wet floor
Wear rubber-soled shoes
Keep one hand behind your back when touching the panel
If you smell burning or see scorch marks, call an electrician immediately
Turn off the main breaker if there's any doubt

Step 1: Identify the Problem Circuit

Locate your breaker panel (usually in basement, garage, or utility room)
Find the tripped breaker - It will be in the "off" position or middle position
Note which circuit it controls - Should be labeled (bedroom outlets, kitchen, etc.)
Don't reset it yet! - We need to identify the cause first

Pro Tip: If your breakers aren't labeled, now's the perfect time to create a breaker box map. Turn them off one at a time and note what each controls.

Step 2: Unplug Everything on That Circuit

Before resetting the breaker:

Turn off all lights on the affected circuit
Unplug every device - yes, everything
Check for hardwired items (ceiling fans, built-in appliances)
Look for hidden devices (chargers, night lights, etc.)

Step 3: Reset the Breaker and Test

Firmly push the breaker to "OFF" position
Then flip it to "ON" - You should hear/feel a click
Check if it stays on with nothing plugged in

Result A: Breaker Stays On

Diagnosis: Overload or faulty device
Action: Proceed to Step 4

Result B: Breaker Trips Immediately

Diagnosis: Short circuit or ground fault in wiring
Action: Call a licensed electrician - this is serious

Step 4: Find the Culprit Device (Overload Test)

If the breaker stays on with everything unplugged, gradually add devices back:

Plug in and turn on ONE device
Wait 5 minutes
If breaker stays on, add the next device
Continue until the breaker trips

The last device you plugged in is likely the problem.

Common Culprits

Space heaters - Draw massive current (1,500W typical)
Hair dryers - High wattage (1,200-1,800W)
Microwaves - Especially older units
Window AC units - Heavy startup load
Power tools - Table saws, air compressors
Old refrigerators - Compressor issues

Understanding Circuit Capacity

Most home circuits are either:

15 amps - Standard for most rooms (1,800 watts)
20 amps - Kitchens, bathrooms, laundry (2,400 watts)

Quick Wattage Check

To calculate if you're overloading:

Amps = Watts ÷ Volts (120V)

Example:

Space heater: 1,500W ÷ 120V = 12.5 amps
Coffee maker: 1,000W ÷ 120V = 8.3 amps
Total: 20.8 amps on a 15-amp circuit = OVERLOAD

Rule of Thumb: Don't exceed 80% of circuit capacity for continuous loads.

Common Causes and Solutions

1. Overloaded Circuit

Signs:

Breaker trips when multiple devices run
Dimming lights when appliances start
Warm outlets or switch plates

Solutions:

Redistribute loads to different circuits
Avoid using high-wattage devices simultaneously
Install a dedicated circuit for heavy appliances
Upgrade to 20-amp circuit if code allows

Recommended: Kill A Watt Electricity Monitor - Measure actual device wattage ($25)

2. Short Circuit

Signs:

Breaker trips immediately when reset
Burning smell near outlets or panel
Scorch marks on outlets
Sparks when devices are plugged in

Action: CALL AN ELECTRICIAN IMMEDIATELY

This is dangerous and requires professional diagnosis. Short circuits can cause fires.

3. Ground Fault

Signs:

GFCI breaker trips (different from standard breaker)
Moisture near outlets or appliances
Trips more during rain or humidity

Solutions:

Check for water exposure (bathrooms, outdoor outlets)
Look for damaged cords exposing ground wire
Test GFCI outlets (test/reset buttons)
Replace faulty GFCI outlets

Tool Recommendation: Klein Tools GFCI Outlet Tester - Quickly test outlet wiring ($15)

4. Faulty Breaker

Signs:

Breaker is warm to touch (not hot)
Breaker trips with minimal load
Breaker is 20+ years old
Breaker feels loose or wiggly

Solution: Replace the breaker

DIY-able? If you're comfortable working in the panel, yes. Otherwise, hire an electrician.

Cost: $10-30 for breaker, $100-200 professional installation

5. Damaged Appliance

Signs:

Breaker trips only when specific appliance runs
Appliance makes unusual sounds
Visible damage to power cord
Appliance is old or water-damaged

Solutions:

Stop using the appliance immediately
Have appliance serviced or replaced
Check the power cord for damage
Test with a multimeter for continuity

DIY Fixes You Can Do Safely

Replace a Standard Circuit Breaker

Tools Needed:

Steps:

Turn OFF main breaker (cuts power to entire panel)
Test with voltage tester - Verify power is off
Remove panel cover (usually 4-6 screws)
Disconnect old breaker - Loosen terminal screw
Pull breaker out - Unclip from bus bar
Install new breaker - Reverse the process
Test before replacing cover

Safety Note: If you're not 100% confident, hire a professional. Mistakes can be deadly.

Redistribute Circuit Loads

Free Solution:

Map your circuits - Know what's on each breaker
Move high-wattage devices to underutilized circuits
Use different outlets (they may be on different circuits)
Stagger usage of heavy appliances

Example: Don't run the microwave and coffee maker simultaneously if they're on the same circuit.

When to Call an Electrician

Definitely call if:

Breaker trips immediately even with nothing plugged in
You smell burning plastic or see smoke
Breaker panel is hot to touch
Multiple breakers trip frequently
Breaker won't stay on or won't reset
You're uncomfortable working with electricity
House is over 30 years old without electrical updates

Average Cost: $100-200 for diagnosis and minor repairs

Prevention Tips

Regular Maintenance

Test breakers annually - Flip them off and on
Check for warm outlets - May indicate overload
Inspect visible wiring - Look for damage
Update old breakers - Modern breakers are more reliable

Smart Habits

Don't daisy-chain power strips - Major fire hazard
Use appropriate wattage for circuits
Give appliances their own outlets
Unplug unused devices - Phantom loads add up

Upgrades to Consider

Arc-fault breakers (AFCI) - Prevent electrical fires
GFCI breakers - Required for wet areas
Whole-house surge protection - Protect expensive electronics
Circuit expansion - Add capacity where needed

Recommended Upgrade: Eaton AFCI/GFCI Dual Function Breaker - Maximum protection ($60-80)

Understanding Your Electrical Panel

Types of Breakers

Single-pole (15-20 amp) - Most common, 120V circuits
Double-pole (30-60 amp) - 240V for appliances, AC, dryer
GFCI breakers - Ground fault protection
AFCI breakers - Arc fault protection

Modern Code Requirements

AFCI protection for bedrooms (since 2002)
GFCI protection for bathrooms, kitchens, outdoors, garages
Tamper-resistant outlets near play areas

Cost Breakdown

| Solution | DIY Cost | Professional Cost | |----------|----------|-------------------| | Redistribute loads | $0 | N/A | | Replace standard breaker | $10-30 | $100-200 | | Install GFCI breaker | $40-60 | $150-250 | | Add new circuit | $200-500 | $300-800 | | Panel upgrade | N/A (not DIY) | $1,500-3,000 |

Bottom Line

A tripping circuit breaker is usually fixable:

Overloaded circuits → Redistribute devices or add circuit
Faulty device → Replace or repair appliance
Old breaker → Replace breaker
Wiring issue → Call electrician

Most Important: Never ignore a tripping breaker. It's protecting your home from fire. If you can't identify and fix the cause, call a professional.
