Frequently Asked Questions (FAQ)

What is the difference between a circuit breaker and a GFCI?

A circuit breaker protects your home's wiring from overheating due to an overload or short circuit. A Ground Fault Circuit Interrupter (GFCI) is a more sensitive device designed specifically to protect people from electric shock by shutting off power instantly if it detects current leaking to the ground.

Is my old fuse box unsafe?

While fuses are not inherently "broken," they are often outdated for modern power needs. Many older fuse boxes have been "penny-fused" or overloaded, creating a significant fire risk. Most insurance companies now require a transition to a modern circuit breaker panel to maintain coverage.

How do I know if I need a 200-amp service upgrade?

If you are adding an Electric Vehicle (EV) charger, a heat pump, or a major kitchen addition, your existing 100-amp service may not be sufficient. A licensed professional can perform a load calculation to see if your current system is at capacity.
