I believe all the ready to install track crossings that are manufactured today have insulated frogs and require no special wiring at all.
.
If you hunt down an old all metal crossing, or buy a crossing kit with solid metal frogs, then wiring would become a concern.

Living the dream.
I have a 45 degree crossing and same to the 30 degree about the wiring.
That's good to know. Electrical stuff is not my strong point!
Thanks MisterBeasley.
On the Walthers and Atlas ones, the tracks are isolated and no special wiring is required.
It takes an iron man to play with a toy iron horse.
I have a spot on my layout that a 30 degree crossing would be great for operations.
Is there any special wiring required? Powered or non-powered frog etc.
Thanks
