Wiring for Your Hot Tub
To make the hot tub safe and as energy-efficient as possible, it should have good wiring. The sanitation system and the equipment necessary for providing power for circulation is installed inside the pool's walls and is fortified with a ground fault circuit interrupter. Below, you will read about a hut tub's relays and switches. Hut Tub Switches A switch is an apparatus that provides a path for the electricity to pass between two poles or contacts. These are also known as "single-pole, single throw" switches. A hot tub would normally have several single-pole switches, and you need to activate different mechanisms to determine if they are working. These are known as "power-off" tests and are conducted with multimeters that are set on ohms. Turning these switches up when the power is off can trigger thermostats. When the temperature knob is turned up, the slight clicking noise you hear would be the switch closing. The other hot tub switches are the pressure switches and the high limit switches. The latter's reset button pops out when tripped. The switches that control the pressure can also be manually activated by pressing the button underneath the micro switch. Even the time clocks also have switches. These are activated by turning the knobs in a clockwise direction until they click. The single-pole double-throw switch, or the spdt switch, is another common kind of hot tub switch. It allows for two distinct paths for electricity flow. It also provides the foundation for the relay, which is essential for running hot tub systems. Spdt switches are often used for air-activated relays. Most portable hot tubs make use of two-speed pump motors. These motors run in either low speed or high speed, but not both. Hot Tub Relays Serving as mounts for several switches, a hot tub relay can be powered by magnetic coils or air, and can also be called switches. The air receiving relay receives the air that is passes through the tube that is connected to the side of the spa. When the switch is turned on, these relays feed air into the turbine. Sending pulses of electricity to coils of coil-activated relays, momentary air receiving relays cause a plunger or a rod to move and turn on a switch or several switches in relay. Such coils have a voltage of 120 volts, while those with 12 and 240 volts may also be available. Contractors, another type of heavy-duty relay, send heavier current flow to the heater. The wires used in this case are large, as contractors could handle large sizes of wires.
