Risk of Ceiling Backbox Touching Electrical Wire?

I'm in the process of adding a Bower & Wilkins BB 6C and it's going to be pretty close or even touching some electrical wire. After installation, it would also be sprayfoamed.

Would this be okay or should I add a wood barrier between the two before sprayfoaming to keep a gap.

Thanks!
