Hi

I have a bunch of the C8203 track pieces. But when I connect them to my Arc Pro setup I get a power overload failure.

Are there different versions of this type of piece? Is the C8510 a 2xC8203-pack? 

Or when writing this I realise perhaps they always must be connected in pairs?

Do you know?

Yes, you got it right - these analogue crossovers must always be used in pairs.
