It can be done although it is bad practice provided the load doesn't continuously require more that 15 A. You should then use a 15 A fuse to protect the switch. Actually a fuse or circuit breaker is only there to protect the wiring and device and nothing else, e.g., if you run 14AWG wire then you want to protect that with a 15A (or smaller) fuse or breaker. Similarly 12AWG wire should be protected by a 20A (or smaller) fuse or breaker. The receptacles will only accept devices rated for them, i.e., NEMA 5-15R is rated at 125V 15A. NEMA 5-20R is rated at 125V 20A... the 5-20R is commonly known as "T" rated as it will accept either NEMA 5-15P or 5-20P plugs. The 5 indicates that it is a 125V rated 2-pole, 3-wire grounding receptacle.. the 15 or 20 is it's current rating.

Why would you need a 20 Amp Single Pole Switch insted of a 15 Amp?

A 20 Amp single pole switch is needed when the circuit requires higher amperage capacity to safely control the load. Using a 15 Amp switch on a circuit that requires 20 Amps could lead to overheating and potential fire hazards. Always match the switch's amperage rating with the circuit's requirements for safety and proper functionality.


Why would i need a 20-Amp Single-Pole Switch insted of a 15 Amp?

You would need a 20 amp switch when the load controlled by the switch can draw as much as 20 amps. If you have a 20 Amp breaker supplying the circuit then you need to size all switches and outlets on that circuit to 20 amps.


Can you install a 20 amp exhaust timer on a 15 amp circuit?

It sounds to me like the exhaust timer is just a switch. The 20 amp rating that the timer is given is the maximum amount of current that it can handle and still be within its safety specifications. It will work very well on a 15 amp circuit.


What is better 15 amp or 20amp?

The choice between a 15 amp and a 20 amp circuit depends on the specific electrical needs of your devices. A 20 amp circuit can handle more power and is suitable for high-demand appliances, while a 15 amp circuit is adequate for standard household devices. If you frequently use high-wattage equipment, a 20 amp circuit is preferable for safety and efficiency. However, for standard lighting and small electronics, a 15 amp circuit is usually sufficient.
