Not enough shore power.

Timely thread, as I just learned the marina we are getting into has 208 3 phase at the pedestals. The 560DB has a 240V 50A and a 120V 50A. Pedestals are 208V (3 phase) 50A and a 110V 30A.

How/Where do you mount the booster?
 
Reviving an old thread. My boat (2004 550 DA) is set up for 240V, 1 Phase, 50Amp Shore Power. My new marina has 208Volt 1Phase 50Amp service. Uses all the same power cords so only indication of low shore power voltage is at the power panel where the analog meter reads low and the green shore power lights flicker versus steady.

During high demand it seems to vary between 200 and 210V supply. Initially I thought the boat had an IsoBoost Transformer which would self adjust. However, once I climbed back behind the generator and took pics of the data plate I realized its only an IsoTransformer (12KVA). So, no boost.

One of my AC units (240v) started giving me problems this weekend. I know that low voltage can create problems with motors, compressors etc. I'm hoping this low voltage issue hasn't started causing problems. Fingers crossed that it's just a capacitor.

For those that have 208V supply at your home or transient docks and use a buc transformer or something similar, how do you have it rigged for the wet marine environment?

Just a reminder. Make sure the shore power is giving the boat enough power to operate all of the units needing to power off of it. Why this is being said, some of the marinas are not up to date with power supply needed for boats demand. The marina my boat is in only has one 30amp power supply. So a splitter has to be used to power the boat.
That being said. When using a splitter keep a close watch on the reading on the power panel in the boat. The power with all the boats using it at the dock can go below 110.
Point here is run as little as possible when this reading of below 110 shows up. Hot water heater is one unit to shut off. If there are 2 ac units try to get by with just one.
Reason for this information there are a above normal amount of ac units being replaced in the marina my boat is at now. Even ones that were only within two years old are being replaced.
Just a friendly reminder hope this helps some of the boaters out there.

Amen to this. I lost a 110v A/C unit last summer (16 years old, so thought it was time). No sooner did I get the new installed then the control box burned up. Checked my shore power connection and the dock side had a slight burnt look to it, so had them replace it.

But, as you said, it was a VERY hot day, everyone was on the dock and I'm sure A/Cs were cranked....
