Simply and reliably shows the polarity of the shore power.

Works perfectly, easy installation!

Good as always, fast shipping

which often goes to the power grid in foreign ports. But also very important for checking your own on-board electrics. I have already learned several times in foreign ports that phase and zero are swapped, and then the harbor master says that it doesn't matter whether zero or phase are swapped, you can plug in a Schuko plug alternately. A mistake, especially if a 230 volt fuse box is installed in your own ship, where the phase lines run through automatic circuit breakers, there is phase on the sockets despite switching off a circuit on the automatic circuit breaker. Then it can be very dangerous. Everyone who has a shore power connection should install this panel.

Everything great

for what it is intended for!
