no power to left most electrical panel

[JMC]

The left most electrical panel which houses the circuit breakers for the Microwave, Galley Outlets, Outlets forward and Salon Outlets has no power. The two main panel breakers AC Main 1 and AC Main 2 indicate power. I checked everything I could think of short of removing the panel itself and checking the electrical connections.

I appreciate any advice and pointers regarding this issue.

Thank you in advance,

John

I'm assuming you have Marine air so you have 2 shore power receptacles. After each shore power receptacle there is a galvanic isolator (optional) then a ELCI breaker. I would suspect that the ELCI tripped on that circuit. I'm not sure where the ELCI is located on a C30 but I would look in the storage compartment where the cockpit helm is located. The ELCI is located close to shore power inlet.

Yes, there are two shore power receptacles. The two main ELCI breakers are on the panel itself. I reset those and no change. I also swapped the shore power cables and no change. I turned on the generator and no change. Unless there is another breaker somewhere that I am not aware of then I suspect something in the panel itself. Does anyone have any other pointers?

The wiring schematic should be ELCI, main breaker and then distribution to panel. The main breaker/ELCI sensor coil are one in the same with your panel. The ELCI on the C26 and C28 the ELCI is separate. If after a reset of main breaker shows voltage/green light the breaker seems to be working properly but may need to still be tested. There should not be another breaker beyond the main breaker other than individual circuit breakers. Troubleshooting is easy once the panel is removed. All testing is done with shore power unplugged from shore pedestal, inverter battery switch in off position, and generator battery switch in off position. A digital multi or analog meter can be used. I believe an issue will be found between the boats shore power receptacle and the load side of the Breaker/ELCI. Continuity testing between the load side of the breaker and the boats shore power receptacle will prove AC power is available thru the breaker/ELCI if not this is the fault. A faulty main breaker will show no continuity. If continuity is proven between the hot (black) and neutral (white), also test the ground (green ) at the load side of the breaker. Breaker/ELCI is good. Inspect for loose connection, open connection, corrosion causing high resistance, between the load side of the breaker and the distribution terminal strip that feeds all the AC circuit breakers. A continuity test can be done to prove no open or high resistant connections. I believe it will be something simple and more time will be spent troubleshooting then fixing. Hopefully a C30 owner has experienced the issue with a direct cause and fix. Good luck!

Thank you for the advice.

After further troubleshooting, it occurred to me that the left part of the panel is energized by the inverter, which led me to the error code on the inverter panel, which is not defined in the manual. Cutwater support contacted the manufacturer of the inverter Kisae for information. The bottom line, I purchased a new inverter at West Marine, same model IC122055, and replaced it. All is well again.

From Kisae, the inverter manufacturer:

The “r2.0” is the software version number of the detachable (remote) display panel. This message should appear temporarily (for about 1 -3 sec) during the initial period after turning the unit on. It should be followed by the main board software version (e.g. “u3.0” or similar) before finally starting operating normally (after about 6–9 sec. in total). My apologies for not being explained in the owner’s manual.

If the “r2.0” message remains steady on the display (i.e. for more than 10 sec.), it would mean there is a communication problem (e.g. in the cable and/or main unit board) between the detachable panel and the main unit.

If the detachable panel has been installed remotely (as per your case according to your attached picture), make sure that both edges of the corresponding long cable (shown below) is actually plugged to both the remote and the main unit, and try to check its continuity and conditions based on the following pinout information (find it attached as well).

IMPORTANT: Do NOT cut (e.g. with a plier or scissors) or manipulate the contacts of the RJ12 cable of the detachable panel (e.g. by cleaning its contacts with a brush with metal hairs, etc.), when it is plugged into the unit, even with the unit turned Off.

NEVER use the optional remote On/Off switch (S/N RM1201-00) for units with detachable panels like this one. Doing so would damage the unit immediately. The RM1201-00 remote On/Off switch is intended for our single inverters series only.

If the detachable panel has been installed remotely (i.e. by using the long cable provided in the box), try to check the continuity and conditions of the RJ12-6-pins in their plugs, based on the attached pinout information.

If everything results unsuccessful and the display continues showing a steady (>10 sec.) “r2.0” on the display, as per your case, definitely the problem is in the main unit (please check the possible reasons for a steady “r2.0” message on the display after my signature below).

If that is the case, the entire unit has to be replaced with a new one (I hope it is within our one-year warranty since the date the boat was sold) .

In that sense, please provide me with the following information:

The serial number of the damaged unit. It is a 10-digit number starting with KT…….. on the barcode sticker located on the bottom metal flat cover of the unit. It is on the original box as well. If it is difficult to access it now, please do not forget to send it to me later, after swapping the unit with the new replacement one.
The proof of purchase. It is required to check the warranty condition of the unit. It could be a copy of the boat invoice/receipt. If you do not have any proof of purchase in writing, please let me know.
The shipping address where we have to ship the new replacement unit to.

That makes total sense. I always forget about the inverter using the transfer switch. When it is working properly it is a good feature. When there is a failure you can loose power to the portion of the panel it is wired to. I elected to not use the transfer switch for that reason. I wired the shore power directly to the panel and the inverter output directly to the panel and use the rotary switch to do my physical disconnect of hot and neutral while one is not in use..
