Shore Power Electrical Panel

[bobrim]

I recently bought a 2000 SCR 2700. It has two connections for shore power on the port side of the boat.

The electrical panel has two breakers labeled "Line 1 Dockside Master" and "Line 2 Dockside Master". On the Line 2 side, there is a sliding cover labeled "transfer" with another breaker under the cover on the transfer side.

I understand that I have to have power on line 1 to run the air conditioner or power connected to line 2 to run the battery charger, etc.

My question...what does the "transfer" switch do?

Thank you,
Robert

I have a 2001 2900 SCR and my Line 1 & Line 2 both have the "transfer" cover - on mine it is to transfer from shore power to generator.

I do not have a generator, so maybe I just don't ever need to bother with the transfer.

Thanks for your help!

Typically line 2 is for the air conditioning and line 1 does the rest of the 120VAC.

Not sure what the transfer is for.

A friend has the same boat I'll ask to see if he has this transfer.

Transfer serves two purposes:

1) If you have a Generator, it will go to 'Line #1'. Then you slide the lock to cover Line #2, which exposes the Transfer Breaker. Turn on the Transfer Breaker and it bridges the input from Line #1 to Both Line #1 and Line #2.

2) If you only have a single shore power plug on the dock, you can plug your shore power cable into Input #1, turn on the Line #1 breaker, then turn on the Transfer breaker and the shore power cable is powering both Line #1 and Line #2 at the panel.

Thank you Shrew! I guess if I only hook a cord from a 30a shore outlet to the boat I have to be careful about overloading the breaker when I'm using option 2 and feeding both line #1 and #2.

Exactly, confirmed with my friend.

You'll trip the breaker on the dock or on shore. I only did it once on my boat while using AC, stove, and microwave all at the same time on only one cable. I use a Y splitter, though, because I only have one shore receptacle.
