A piggyback circuit breaker, also known as a tandem or double-stuff breaker, combines two separate circuits into a single slot in a breaker panel. This design allows adding more circuits without a larger panel, making it a space-saving solution. Each breaker in the piggyback unit operates independently, protecting two circuits in one standard breaker slot. This is especially useful in older panels with limited space for additional breakers.

A C-wire connects your thermostat to your household heating and cooling system to provide continuous 24V power. The furnace's transformer converts household electrical current into this low-voltage power to operate the HVAC system's circuitry. In most configurations, the C-wire connects to the terminals labeled "C" on both the furnace's low-voltage terminal block and the thermostat. In some cases, if a dedicated C terminal is unavailable, the C-wire can be connected to the "G" (fan) terminal at the furnace.

No, it’s not normal. When an outlet is hot, something is wrong. Our tips above may help you pinpoint the problem, but when in doubt, always bring in a qualified electrician to deal with the issue. 

The key difference between a circuit breaker versus a surge protector is that circuit breakers shield your entire electrical system from overcurrents and faults, while surge protectors defend your electronic devices against voltage surges and spikes. A circuit breaker interrupts the flow of electricity in a circuit when it detects an overload or short circuit, protecting the wiring from damage and preventing fires. In contrast, a surge protector shields electronic devices from voltage spikes, such as those caused by lightning strikes or power surges, preventing damage to the device’s inner mechanics.
