If not they can be installed together in a secure location nearby for easy viewing but bust be in line with your shore power input cable.

#Reverse polarity outlet install#

Reverse polarity lights and this switch are easy to install if you have room at your switchboard. If you travel around a lot from dock to dock, one option is to get a reverse polarity switch put in which you can use to just turn in this situation and continue using your boat without rewiring anything. Most marinas have a service man who can come and change the wiring of the dock power outlet to suit your vessel. How do you fix this? Well the first thing is to turn off you main switch that supplies your main switchboard and unplug your shore power lead. This can create a dangerous touch potential and is very serious. This earth bar connects to all your metal frames and items on your AC systems. If the Active and Neutral conductors are now switch, not only is your Neutral bus Active but so too is your Earth bar.

As I mentioned before, in some cases there is a connection between the Earth and Neutral bus bars. You now have switched the Active and Neutral conductors around and the Neutral and Earth bus bars that were before safe, become live. When reverse polarity occurs from the dock side supply. You can place one lead in the outlet’s longer vertical opening. You can now turn on the multimeter by turning the knob in the middle into Voltage AC. Then, you can plug the red lead on the right input. This is ok and safe as long as the Active supply doesn’t get connected to it. Plug black lead in the middle input on the bottom of your multimeter. In some switchboard installations, not all, there is a connection between the Neutral and Earth bus bars. Your Neutrals all get join together and your earths all get join to each other on bus bars. Your AC circuit protection switches the Active conductor. Now because of the way switchboards are wired. The shore power cable that connects the dock power to your boat has 3 cores inside. On most boats 70ft and under, the shore power lead supplies your vessel with 110v AC power. This can happen for multiple reasons which I won’t go into today but when it does happen you need to know what it means and what to do. Reverse polarity lights indicators light up when our connection to the dock power is connected but the active and neutral conductors don’t marry up with the same conductors on the dock side. The following is a guide of what to do when you find your boats reverse polarity lights come to light. As we move from place to place we can sometimes come across situations we haven’t experienced before. One of the many reasons we love being a boater. I know this is not the ideal solution but in a real world scenario is it what you would do.As a boater we love to travel. My first thought is to sleeve the wires at the socket outlet so the sleeves represent the correct colours for the conductors, and reverse them around so that thay are in fact correct polarity. So it really isnt practical to rip out the cabinets, what would you do. No junction boxes under the kick boards and no cut outs in the back of the cabinets. The problem is this was in a kitchen and i think the spur was put in first then the kitchen because i cannot trace the spur connection back to any of the accessable sockets. So fair assumption that the other end of the spur where its taken off the ring has been wired in reverse. Did a visual check at the CU and it was wired correctly. Took the socket outlet off the wall and the conductors are wired 'correctly' but it is a spur.

Plugged in the tester and low and behold the machine showed a reverse polarity on the socket outlet. I went to a rented property today for a PAT test.
