Neighborly Done Right Promise Logo

The Neighborly Done Right Promise® delivered by Mr. Electric®, a proud Neighborly company.

Residential and Commercial Electrical Services in St. Louis

We see it every day in St. Louis: 60-amp or 100-amp electrical panels struggling to handle air conditioning, home offices, kitchen appliances, and electric vehicle charging stations. Many homes in this city were built before 1950, and have outdated electrical wiring, undersized panels, and electrical systems never designed for modern demands. Add in issues like ungrounded outlets, aging circuit breakers, and knob-and-tube wiring still hiding in walls, and you have a system working far harder than it should. Our licensed electricians specialize in bringing older homes up to code while delivering reliable electrical solutions for every home or business need. From a 200-amp electrical panel upgrade to whole-house surge protection and Level 2 EV charger installation, we deliver safe, code-compliant work backed by the Neighborly Done Right Promise®.

Frequently Asked Questions About Electrical Services in St. Louis

  • A circuit breaker trips when it detects an overload, short circuit, or ground fault. The most common cause is circuit overload, which occurs when too many devices share a single circuit. This is especially common in older St. Louis homes where 15-amp circuits were standard and far fewer outlets were installed. Here is how we diagnose it: the first thing we check is whether the breaker trips under a specific load or immediately on reset. If it trips once and resets successfully, an overload was likely the cause. If it trips immediately after resetting, or trips repeatedly, you have a more serious problem. A short circuit occurs when the hot and neutral wires touch, creating a dangerous path for current.

    A ground fault happens when electricity finds an unintended path to ground. Loose connections inside outlets, switches, or the panel itself create resistance, generate heat, and trip circuit breakers. Old or failing breakers, particularly in Federal Pacific or Zinsco panels common in St. Louis homes from the 1950s through 1980s, fail to trip during an overload or trip when they should not. Do not keep resetting a breaker that trips repeatedly. Call a licensed electrician to diagnose the problem before a fire starts.

Dangers of an Overloaded Circuit

Overloading an electrical circuit can cause some serious problems. While that may seem obvious, chances are that you’ve caused a circuit overload at least once in your life.
