2 quick questions

[Ty.the.railroad.guy]

I have two quick questions and hopefully I won't have to use this forum again for awhile.

1. I would like to use a turntable with my layout but due to limited space and my lack of talent of wiring to use the walthers brand I'm considering buying the bachmann brand since all of the track I'm using is EZ track. So my question about it is: as long as I don't turn the engine a full 180 degrees, it won't cause a short in the locomotive right?

2. I own a few of the crossovers and some of the #4 turnouts as well as a #5 turnout. From the instructions I've read some say I should power the frogs on a dcc layout but others say I shouldn't. So what's the difference and should I or should I not power said frogs?

Thanks

Powered frogs are generally a good thing. SHort wheelbase locomotives like the 0-6-0 or 44 tonner can stall on unpowered frogs.

Quick answer: Yes. Or no. It depends.

Longer answer: The locomotive itself triggers the short, but it's the power in the wiring that causes the short. If the polarity in the bridge rails is opposite to the polarity in the rails the locomotive is moving to / from, BOOM! The Goddess of Electricity screams at you. How to avoid this is highly dependent on your setup and technical prowess. My personal favorite is bi-color (red / green) LEDs. Wire them across the power gap, red indicates different polarities, green equal the same polarity. You can mount it in a dwarf signal head on regular tracks, and as a signal light over the roundhouse stall for those tracks.
