In this article, we’ll discuss the different components of a 4 wire hot tub wiring diagram and how to install it. If you’re looking for a comprehensive guide to wiring your 4 wire hot tub, you’ve come to the right place. However, setting up a hot tub wiring can be a complicated process. Having a hot tub in your home can be a great way to relax after a long day. Just for reference sake, the box on the side of the home is a positive disconnect type that I can completely disconnect the spa's HOT wires by removing a stint, that leaves the common and the ground wire going to the spa and even in that scenario it trips the GFI immediately.Home » A Guide To 4 Wire Hot Tub Wiring Diagrams A Guide To 4 Wire Hot Tub Wiring Diagrams I think it's hooked up properly, I just want somebody to say 'yes, that is how a three wire connetion is made', for obvious reasons I want to be sure it's correct! The way I have it now I have the ground wire in the panel run to the external box on the side of the home so that box is grounded, from there I only have the red,black and white wires run to the spa, that is the only way it will work without tripping the breaker. I followed the green/ground wire from the main connection on the spa and it is grounded to the box as well. Looking at the schematic and at the tub, both the pumps and the blower are grounded to a buss bar on the side of the spa control box. The neutral line is allowed to have current flowing on it - usually relatively small if the loads are balanced properly, but the ground line is NEVER supposed to have any current flowing, unless there is a fault condition.ĭo you see any obvious safety ground wiring in the spa, e.g., wires connected to the cases of the motors, heater, etc.? If so, where do these wires connect together? From that point on, the neutral and ground connections must be separate.

At your main panel (service entrance), the neutral and ground wires from all the circuits should be bonded together - and ONLY there. Look at the schematic and where the AC comes into the tub notice there is NO common only a ground and you will understand why I'm confused.I hopeįor a four-wire 220V service, you have the two AC line wires, the neutral wire, and the ground wire. I looked at that wiring scheme before I started doing any of the wiring and If you look at the actual schematic in the instructions there is a 'ground' wire which makes it appear that there would be no common wire? I have the red and black (hot) wires hooked to the load side of my GFI breaker and the white (common) wire hooked to the 'Load Neutral' on the breaker and the pig tail attatched to the buss bar but I'm thinking because I ran a ground wire as well as the common, there is a ground loop. Those glimpses into my children's hearts, or moments of open communion with my wife are beyond price. At one time or other I have had heart-to-heart talks with each member of my precious family in the family spa, usually when we are the only ones in the tub, and sometimes in the wee hours of the morning. It also has been a place to get close to family members: my wonderful wife of 27 years, and our two kids. It helps me when the stress of being a business owner keeps me awake at night. If you can think of a way I could do this job better, please let me know.I get a great deal of enjoyment out of my own spa - I injured my back many years ago and it helps relieve the pain so I can function.

I spend a lot of time trying to help people figure out the buying process, and later the ownership of these big boxes of hot water that seem to be able to bring joy to our lives. Interests: I am a volunteer moderator here and on other boards like this one.
