Frequently Asked Questions

Embarking on a home renovation or addition is an exciting venture that can significantly enhance your living space and property value. However, it’s crucial to consider the capability of your current electrical system to support these new demands. At Mainstream, your safety and the efficiency of your home’s electrical infrastructure are our top priorities. Here’s why an electrical upgrade might be essential for your renovation project:

  • Capacity for Expansion: Modern lifestyles and appliances necessitate approximately 200 amps for a home’s electrical demand. Yet, many older homes are equipped with electrical systems designed for much lower capacities — some as low as 40 amps. As you plan your home addition or renovation, it’s essential to assess whether your existing electrical panel can handle the increased power requirements or if an upgrade is necessary.
  • Panel Limitations: If your current electrical panel is maxed out with no room for additional circuits, you may need to consider installing a larger panel or an additional one to accommodate your renovation plans. While updating your electrical panel represents an additional expense, it’s a critical investment in the safety and functionality of your home. Cutting corners on electrical work can lead to significant risks.
  • Safety and Code Compliance: Especially in older homes, your electrical system may not only be underpowered for today’s needs but also potentially not up to current building codes. Upgrading your electrical system ensures that your home can safely handle the increased demand from new appliances, additional outlets, and more, keeping your home safe, efficient, and compliant with local regulations.
  • Mainstream’s Expertise: With years of experience in electrical, heating, cooling, and plumbing services in the Spokane area, Mainstream is your go-to expert for ensuring your home renovation or addition project is supported by a robust and code-compliant electrical system. Our team of certified professionals is ready to assess your needs and provide solutions tailored to ensure your project’s success.

Don’t let outdated electrical systems hold back your renovation plans. Contact Mainstream today to ensure your home is prepared to meet the demands of your exciting new project. Our commitment to quality, safety, and efficiency makes us the trusted choice for homeowners looking to enhance their living spaces. Let us help you navigate the complexities of electrical upgrades with ease and confidence.

While having both a GFCI outlet and a GFCI breaker can provide extra protection against electrical shocks, it’s not always necessary. The need for both depends on local electrical codes, cost considerations, and the specific areas in your home. GFCI outlets are commonly used in areas with water exposure, like bathrooms and kitchens – while GFCI breakers typically go in the main electrical panel for broader protection. In many cases, consulting an electrician to assess your needs and ensure code compliance is wise.


Yes, you can use a GFCI outlet and a GFCI breaker in the same electrical circuit. While this may provide additional protection against electrical shocks, it’s not always necessary in all situations. GFCI outlets are commonly used at specific outlets in areas with water exposure, like bathrooms and kitchens, while a GFCI breaker in the main electrical panel can provide broader protection for the entire circuit. However, ensuring they are correctly wired and do not interfere with each other’s operation is essential. Consulting a licensed electrician is advisable to ensure proper installation and adherence to safety standards and electrical codes.


GFCI outlets and GFCI breakers safeguard against electrical shocks but vary in placement and scope. GFCI outlets are positioned at individual electrical outlets, whereas GFCI breakers are integrated into the main breaker panel. Installing GFCI circuit breaker protects your entire electrical system, while a GFCI outlet only safeguards one specific outlet.

These two options ultimately depend on your specific home or business requirements. GFCI outlets are ideal if you want to comply with code requirements. On the other hand, if you seek the utmost protection available, GFCI breakers offer a superior choice.

Ground Fault Circuit Breakers last 30 to 40 years, but the average life expectancy is 35. This is longer than the 15 to 25 years life expectancy of GFCI outlets. Before determining the right time to replace your circuit breaker, it’s crucial to understand the kind of outlet in your home.

Standard three-prong outlets, the most common in the United States, can serve you for up to 30 years. However, if the outlet is in regular use, it should be changed after 15 to 20 years. However, two-prong outlets lack grounding wire, which makes them less durable. It is therefore advisable to replace them with a three-prong outlet for better protection.

Circuit breakers can go bad or wear out and fail. Just like any other electrical equipment, GFCIs also experience wear and tear at some point and should be replaced immediately. There are many causes of a worn-out circuit breaker, including overloading the outlet and loose wiring.

Moisture in a room can accelerate rust on the metal screws of your GFCI device, serving as wire connection points. At the same time, your circuit breaker can wear out due to age. Electrical codes dictate installing new GFCI devices if they start tripping abnormally and have been in service for over 15 years.

Ground Fault Circuit Interrupters stop working or trip whenever there’s an overload or abnormal readings. The internal current transformer senses these readings. Although a trip is an ordinary thing, you should not ignore it. Apart from resetting the GFCI, it’s advisable to investigate the cause.

Many things cause the tripping, including conductive dust, worn insulation, water, or other soft grounds. Ground faults cause 80% of equipment short circuits, while insulation deterioration on cables and wires causes 90%. If you or your loved one becomes the unintended path, ventricular fibrillation, which leads to cardiac arrest, can occur.

Ground fault circuit interrupter outlets are now required in areas like kitchens, bathrooms, and garages, where the risk of electrical shock is greatest. However, some older homes may still have the original, standard outlets in these locations. GFCIs can be identified by the “test” and “reset” buttons located on the receptacle. These outlets help protect you from electrical hazards by monitoring the amount of electricity flowing in a circuit. The moment the outlet detects an imbalance in the flow of electricity, the GFCI cuts off power to the outlet.

Installing a GFCI outlet greatly reduces the risk of electrical shock. They also help prevent fires, an especially important function in areas like kitchens where high-voltage appliances are frequently in use.

All mass-produced electric vehicles today include a 110-volt-compatible (Level 1) charging unit which is able to be plugged into any standard 110v household outlet.

Installing an outlet or EV charging equipment on the exterior of your house is completely safe.  Almost all EV power connectors are NEMA 3R rated.  This means that they can withstand wind, rain, snow, and ice without failing.  They are not submersible, however, so installing a power connector or EV outlet in a place that can be flooded is not advisable.  

AFCI is short for “Arc Fault Circuit Interrupter.”

AFCI outlets are designed to protect your home from fires caused by arcing faults. Arcing faults occur when loose wire connections or corrosion on your wires lead to sparks or arcing, which often leads to electrical fires. AFCIs detect these arcs on the circuit and respond by cutting off electricity.

GFCI is short for “Ground Fault Circuit Interrupter”.

GFCI outlets are most common in rooms with plumbing, like bathroom or kitchen sinks. These outlets are designed to protect people from severe electric shocks.

Ground faults are an abnormal, unintentional electrical path that directs current into the ground. Ground faults happen when an electrical current escapes a home’s insulated wires as a result of damaged wires. A GFCI outlet detects the flow of a home’s electrical currents through the wiring and senses the presence of a ground fault. If ground faults are found, the GFCI outlet shuts off the flow of electricity to prevent a person from receiving a potentially fatal shock.

If your electrical outlets are no longer able to hold the prongs of a plug, or are providing inconsistent power, it’s time to call an electrician to come fix or replace them.

Broken outlets can cause serious shock and fire hazards, and should be inspected at the first sign of damage. Some signs to look for include:

Discolored Outlets

Signs of discoloration indicate overheating, which is a serious problem.

Sparks or Smoke

If an outlet emits sparks or smokes when an appliance is plugged into it, something is wrong. There is a good chance the outlet was exposed to water or short circuited.

Cracked Outlet Plates

When an outlet’s cover plates become cracked, its wires can become exposed, which presents a shock risk and fire hazard. When this happens, it’s best to shut off power to the outlet, or at the very least avoid using it until it can be replaced.
