(the grounds will of course be connected.)
Is there a reason not to upgrade your system to a single 50A service?
You could then use just one shore power
cord. [Albeit a larger gauge for 50A]
Our 50A inlet is split into 2- 110VAC feeds at the distribution panel.
This also allows us to use a 30A shore power
cord with a 50A boat-side socket on it [with the single 30A hot jumped to the 2nd hot on the 50A plug
on the cord] for feeding both sides of the distribution with the 30A service when that is all that is available or needed, or when all we want to schlep is the 'smaller' cord...
If twin 30A services are all that are available, and you need the extra amperage, you can use a 'smart reverse Y' adapter with your 50A cord. [e.g., Marinco RY504-2-30
This is a safe and very flexible set-up, and only requires one shore power.
You can also use the 50A cord to a 30A service with the right adapter. [e.g., Marinco 111A
In case this is helpful.
Best wishes with your project
PS: If you go the 50A route
, [or even stay with twin 30A inlets] may I recommend upgrading to the Smart Plug
on your boat? [If you haven't already... Here is our blog post
explaining why we chose this upgrade...]
