T&T: 30 amp service vs. 50 amp service

[ron barr]

SNIP:"I you have a 30/50 splitter that plugs into a 50 amp 
receptacle then you are utilizing a 50 amp service, with a pair of 50 amp 
breakers tied together. after having used a 50A cable for awhile, I much 
prefer a splitter and two thirties tied into a 50 amp service.That 50 amp 
cord is like an python, and expensive !" Bob England

I don't quite get what you are saying here Bob. If I take two 30A's the first
question is whether they are on the same phase or not- that affects what I can
pull.
Secondly where do the two 50A breakers you mention come from? The shore has two
30A. 
Finally these Y's cost close to $400 new - although some are a lot cheaper at
consignment stores - curious whey are so many around second hand- people tried
them and had problems maybe with phase matching? Given that price a 50A python
may be cheaper!
