In your experience, do see ventilated NEMA 3R transformers installed in areas accessible to the public?
All of the ventilated NEMA 3R transformers that I have seen have a rain guard and also an internal screen shield.
Do you feel this is adequate to prevent tampering from vandals and/or a child poking a stick in the opening or is a NEMA 4 totally enclosed, non-ventilated transformer the better option?
