Marino 50A 125v/250v to 30A/125v pigtail question

[shimari]

I know this pigtail takes one leg of the split phase 50a/240v to provide essentially 50A/120v single phase. Are there any balance issues between the legs by using this pigtail? I thought I had read about getting the legs out of balance with largely different loads can create issues.

TIA

Are you using a 50 to 30 converter? If so, no issues. At least I have never had any and I have used mine multiple times at multiple places.

If using only one side of the 120/240V 50A connection causes a problem, the marina has some serious wiring issues

Thanks Hartley - I presumed that since Marinco wouldn't offer the pigtail if it created problem. Not sure why I was thinking about a balance problem.

Reading the Internet too much probably!

The problem with this [all step-down] pigtail adapter[s] is that: The pigtail, 30 shore power cord [pigtaill to boat], and 30A boat inlet are ALL UNPROTECTED, until you reach the boat’s 30A main breaker.

You're plugging a 30Amp device [#10AWG wire & 30A female cord cap] into a 50A receptacle, protected by a 50A breaker.

Being part of a portable cord set assembly, intended for temporary, attended, use, electrical codes permit this; although I don’t consider it ‘best practice’; especially considering the long-term, unattended use, boats often subject shore power connections to.
