While the term "15+ Amp Switch Box" might be used commercially, it's not a standard term you'd typically encounter at a hardware store or used by electricians.

There are two main interpretations of what this could refer to:

A switch rated for 15 amps or more:  Most household light switches are rated for 15 amps, which is sufficient for controlling standard lighting circuits.  However, some heavier-duty switches,  used for appliances or high-powered fixtures,  might be rated for 20 amps or higher.

A box containing a switch and rated for 15 amps or more: This could describe a  junction box  that houses a switch and allows for connections to multiple wires.  The 15 amp rating would again refer to the capacity of the wiring and switch within the box.

Here's a breakdown of some common electrical switch box types you might be interested in:

Light switch box: A standard box containing a switch for controlling lighting circuits (usually rated 15 amps).

Single gang switch box: A box that can accommodate one switch.

Double gang switch box: A box that can accommodate two switches.

Weatherproof switch box: A box designed for outdoor use with a weatherproof seal to protect the switch from moisture.

GFCI switch box: A box containing a Ground Fault Circuit Interrupter (GFCI) switch for added safety in areas with moisture, like bathrooms or kitchens.

Finding the Right Switch Box:

Identify your needs: Consider the number of switches you need (single or double gang), the location (indoor or outdoor), and any safety features required (GFCI).

Match the amperage rating: Ensure the switch box and switch have the appropriate amperage rating for the circuit you'll be using (typically 15 amps for household lighting).

Consult a qualified electrician: If you're unsure about the type of switch box you need or are uncomfortable with electrical work, consult a licensed electrician for advice and safe installation.

Important Safety Reminders:

Always turn off the power: Before working on any electrical wiring, turn off the power to the circuit at the breaker box and use a voltage tester to confirm the power is off.

Leave complex work to professionals: If electrical work involves rewiring, modifications to your electrical system, or you're unsure about any steps, it's best to call a licensed electrician to ensure safety and code compliance.
