Frequently Asked Questions

Your circuit breaker is designed to protect your electrical system by shutting off power when something isn’t right. If it trips frequently, it could be due to:

  • Circuit overload (too many devices on one line)
  • Short circuits (faulty wiring or appliances)
  • Ground faults (accidental paths between electricity and ground)
  • A failing breaker itself

At D33 Electric LLC, we’ll test your circuits and panels. We will pinpoint exactly what’s causing the issue and recommend the safest, most efficient solution.

Outlets fail for a number of reasons, including:

  • Tripped GFCI (Ground Fault Circuit Interrupter)
  • Loose wiring or disconnected terminals
  • A blown fuse or tripped breaker
  • Internal damage due to overheating or electrical surges
  • Aging components

We’ll inspect the outlet and connected wiring to identify the root problem. Then, we'll replace or repair the components as needed.

No. Attempting DIY electrical troubleshooting is dangerous and can result in:

  • Electric shock
  • Fires
  • Worsening the issue
  • Code violations

Even if the problem seems simple, it's best to let a licensed, insured professional handle it.

The cost varies depending on the following factors - 

  • The complexity of the issue, 
  • The size of the property, 
  • and the time required. 

On average, a professional diagnostic starts around $150. We always provide transparent, upfront pricing.

If only part of your home loses power:

  • Check your breaker panel for tripped switches.
  • Reset GFCI outlets, especially in bathrooms or kitchens.
  • Unplug devices from affected outlets to prevent surge damage.
  • Call us immediately if the problem persists.

This could indicate a failing breaker, poor wiring, or serious panel issues. We can diagnose and fix it quickly.
