Otherwise grounding of each location is required to meet code. Then the factory white wire curly to go to the neutral bar. Contact us at with any questions about the proper installation of your spa. At the outlet, plug in a lamp to be sure the power is on. I went around the house to check out every one of those I can find, and the last one in the other bathroom was the culprit. The reason for the connection to the neutral on a sub panel or the ground bar on a main panel is to give 120v loads a ground for the circuit to operate.Next
Wiring for a 20 Amp, 240 Volt Appliance Circuit Breaker This circuit breaker wiring diagram illustrates installing a 20 amp circuit breaker for a 240 volt circuit. This will help to prevent any loose wire from snapping off the device even partially and touching electrical box common for stranded wires if improperly installed — see pictures under 3 section. If the circuit breakers aren't labeled, you can locate the proper switch by plugging a radio into the outlet you plan to change. Psychologically, some of them become forgotten because they have never been actively used. In the event of a wiring problem with the hot tub, the breaker interrupts the flow of electricity, helping to prevent injury or death.Next
The outlet may also indicate appropriate color connections. The white wire is used for hot in this circuit and it is marked with black tape on both ends to identify it as such. After the Installation Once your spa is wired up and ready to go, it will need to be filled with water and you will need a kit. Normally there is continuity between neutrals and grounds at a receptacle, because both are ultimately attached to the neutral bar at the main panel. Simply plug in an appliance, turn it on, and press the test button. One is whether either term refers to a receptacle-type or to a circuit-breaker-type interrupter.Next
These are also required in hospitals where sensitive medical monitors may be affected by grounding noise in the wiring which can cause disruption in their critical functions. The neutral to the bus is to provide 120 volts for operation of the solenoid trip. Disperse the load by plugging some of the appliances involved into another circuit. Put the outlet back into the box, screw it into place and attach the cover plate. But most commonly it is for various faults downstream in wiring or plugged-in appliances -- both dangerous and harmless faults.

In the J box the grounding conductors from the three outlets tie together and go back to the ground bar. If it is not, press the red button and power should be restored. For example, in the dining room for protecting the kitchen, or indoors for protecting an outdoor outlet. And they do not prevent overloads on the circuit. Test the outlet with the circuit tester to be sure the power is off. These tips and suggested procedures are free and for informational purposes only.
Before doing this test, be sure none of the three holes of the receptacle shows voltage above 12 from itself to the ground hole of an extension cord plugged into an outlet elsewhere. The 2-pole is designed so that all 3 wires the two ungrounded-conductors and the one grounded-conductor pass through the same pickup core for current sensing. Tell us who you are so we can provide you with the information that is most important to you, and help you find what you are looking for faster. A conduit trench is dug being sure to check with local utility company to assure there is no buried cable or pipe there from the foot of the disconnect box to the spa. The switched item's neutral should attach to the corresponding neutral terminal: Load or Line. I don't think I was going to sleep tonight because I was so aggravated by this! Electrical Circuit Breaker A guide to home electrical circuit breakers and how they work to protect your electrical wiring.
For most exterior spas, the electrician will run a 4-wire number 6 or number 8 wire to the spa location. I have come across only two cases of defective tripping. This was a brand of Hot tub that was fed from a 2 pole 30 amp and 2 pole 20 amp breakers. Mount the box in a location that is protected from the weather and convenient to the hot tub. Note: Before reconnecting each load, check for frayed cords or a damaged plug on appliances or lamps. These arcs typically occur out of sight; inside walls or electrical devices day or night.Next
Use of the above content is for information purposes only and releases the author or company employees from any liability. For instance, it will trip if the bare ground wire in a box happens to be touching the neutral screw of a protected receptacle. Disconnect all of the wires to the outlet. Never connect a 4-wire hot tub to 3-wire service. After all, we are all human and make mistakes! Consider calling a nearby electrician. Circuit Breaker Panel Box Wiring Diagram This diagram illustrates some of the most common circuits found in a typical 200 amp circuit breaker service panel box.Next
