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.
Can I use a 30 amp circuit with a 12 gauge wire to handle a tablesaw that runs at 13 amps under load but spikes above 30 amps on turning on as the 20 amp circuit kept tripping at turn on?
It is not safe to use a 30 amp circuit with a 12 gauge wire for a tablesaw that spikes above 30 amps on startup. This setup can pose a fire hazard and may not provide adequate protection. Consider upgrading to a properly sized circuit and breaker to ensure safe operation of your tablesaw.
What would cause a 12 volt motor to change polairity?
A reversal of polarity in a 12-volt motor can occur if the wiring connections are switched or if a DPDT (double pole, double throw) switch is used to change the direction of current flow through the motor. It can also happen if a control circuit such as an H-bridge is used to control the motor direction.
Is a 15 amp power tool better than a 12 amp?
Not necessarily. The amp rating of a power tool indicates its motor's power consumption, not necessarily its performance. Other factors like quality of construction, design, and intended use will determine the overall performance of the tool. Choosing between a 15 amp and a 12 amp tool should be based on the specific requirements of the task at hand rather than just the amp rating.
What is stronger 9 amp or 12 amps?
A 12 amp current is stronger than a 9 amp current because amperage is a measure of electrical current flow. More amps indicate a higher flow of electricity, which means a 12 amp current can power larger devices or provide more energy than a 9 amp current.
