Single-pole switches are simple circuits designed for lower voltages. As such, they don’t require the complex wiring of switches that need to supply power to larger devices and appliances. This is why single-pole switches commonly go in bathrooms, closets, and other small rooms that power a low-watt light fixture. One wire creates the circuit from the power supply, the other goes to the fixture, and the final wire provides safety mechanisms through grounding.

If you’re moving wires, installing new wires, or installing new fixtures in the space you’re insulating, then you will need to hire a licensed electrician to do that portion of the job for you. However, if you just intend on replacing old insulation or adding new insulation over existing insulation, then you don’t need to hire one. Your insulation installer will work around wiring, fixtures, outlets, and switches, even if they’re installing fiberglass batts in the voids where wires run. However, you will need an electrician if you suspect a problem with your wiring during the insulation work.

Switching the hot and neutral wires in an outlet or receptacle, a condition known as reverse polarity, is dangerous. While the outlet will still function and provide power, it creates a significant electrical shock hazard because anything plugged into it will remain electrified even when switched off. If you touch a conductive part of the appliance, such as the metal components of a toaster, you could receive an electric shock.

The major difference between a GFCI breaker and an AFCI breaker is that a GFCI breaker protects against fatal shocks while an AFCI breaker prevent electrical fires. A GFCI breaker senses when the electrical current to ground is overloaded and trips to prevent major accidents or injuries. AFCI breakers trip when it detects dangerous electrical arcing.
