Adding /upgrading shore powerwill be adding a second a/c unit for a total of 34000 btu. This will pull 27.5 amps minimum cooling and 37 amps heating.
our E40 has only 30 amps shore power. Not enough to do the job.
Question is, change the 30 amp service to 50 amps, or put in another 30 amp service and run 2 circuits ?
Also, anyone have their electrical panels anywhere else but in the engine room?

I'm not really an electrician but most boats in this size range (coastal cruise) that I see have two 30 amp circuits. If they pull in and only 50 is available they have a splitter into which they plug the two 30s into --- the other end being a 50. The splitter is expensive, about $200 from what I hear.

I just bought a E42 that has two AC units and both breakers are located on the panel at the chart table. Not sure about this but I think I would avoid having breakers and electrical service in the engine room due to heat and spark considerations?
Be sure to check the type of spliter required by the service at the dockside connection since there are al least 3 different types of connections for 2X30 to 50 amp service. the Y connectors are closer to $290 new. I have 2 extra 50' 30 amp shore power cords I would like to sell, $60 for both + shipping (34 total pounds of shipping weight).

A/CBob, I just bought an E40 that has NO A/C. Sense U R adding and
upgrading, can U tell me a good place to look for A/C. And any
recomendations U might have on brand or size. U R going to 34000

Chuck, the unit we have now is a flagship marine 16000 btu unit. Seems to work ok, but for corpus christi, not enough. Its installed in the wet locker behind the nave station. Not a good place imo.
http://www.flagshipmarine.com/selfcontained.html
I could proably go with a 2nd smaller unit, but they have a nice 18500 btu unit, and I figure on some days could just go with that unit, or most of the time use both. I am thinking of adding the 18500 but unit to the engine room, on a shelf aft of the stbd side access doors, and box it in so it is seperate from the engine space. 3 discharges, 1 to aft stateroom, 1 to galley, and 1 to salon. the return air would be the stbd walkthru behing the louverd door. I would use the same thruhull fro intake, and a maybe t' into a different line for d/c.
The foreward unit would go into the port locker foreward in the salon. with 1 duct running to vberth, and 2 to salon. the return would be via the louvers on the locker door. I could use the through hull for the toilet, ( changing it to fresh water flush) and the d/c would be new.
The 18500 unit would cost $2324 with delux kit included. Add some bucks for the teak grills, but I would forgo them for now.
There are benifits to having 2 30 amp units I guess, and benifits to one 50 amp unit. Here in Corpus, I have both 30 amp 110v and 50 amp 110/240v hookups. I could go with a splitter, and 2 30 amps, but then that is 2 times the cords, hookups etc. But there is a whole lot more pucnh to 50 amps, and since I would be doing it myself, while replacing the ac panel from the factory one, might be better to go wtih 2 30's.
ssteakley, what dock are you on here in Corpus? We are on H30, just moved from R dock.
We have a few other endeavours on the dock.

A/C instaalBob, thanks for the input. After looking into the total cost of the A/C unit
and then a generator to be able to run it on the hook it seems 2 B a little out of our reach.

Couple of items:
there are several Y cord options.
single 30 to twin 30; converting a single 30 amp feed into 2 30 amp plugs but still only having 30 total amps from the single input.
Single 50 to twin 30; converting a single 50 amp feed into 2 30 amp plugs. There are 2 varieties of this cord. A 115 volt & and 220 volt version. the newer 220V can also be used on the 115V output feeds. If there is 115V then you will have two 25 amp feeds but if you have the 220 version you will have 30 amps at each plug. At least that is what you should be limited to by the 30 amp breakers in your boat. There will actually be more amperage available but you better not try to pull it from the source as the wires in the 30 amp end will not take it for long.
The last is one you likely will not need. It is to convert 2 30 amp feeds to one 50 amp boatside inlet. This is known as a smart Y adapter and is about $400.
The 30 to twin 30 Y cord is $160 to $200. the 50 to twin 30 Y cord is a little over $200.
If you add a second 30 amp service, you should tie the two together at the breaker physically. When one trips, the other must also trip or you get an electrical hazzard. many boats are wired without the physical connection and can cause safety issues.
Lastly, please switch off the breaker at the dock before disconnecting the cord from your boat. If you don't, that cord is still hot and on a boat that can be dangerous if dropped in the water or if you are standing on a wet deck holding it.

Thanks.
I have decieded to go with one 50 amp 125/240 wired into a 3 pole main breaker and split the house ac loads into a inverter side and a non inverter side. Also thinking about putting a ac/genset transfer switch in for a later installation of one.
The cord for this is not cheap, but after many discussions and looking at both pros and cons, feel this is my best option.
My marina as 30 amp 125 and 50 amp 125/240v hookups.
Thanks.
Let you know how it went. Should start it in January.
