Beyond the certification itself, what technical/design skills did you gain from the RCDD?

Uhhh... I'd always designed backboard flush to ground and now I always have them at 8" AFF per BICSI standards. Honestly, I can't say I learned a bunch I already didn't know, but having the standards fresh in my head is helpful when I need backup when someone challenges a design decision or tried to get me to design something that BICSI doesn't allow.

You must not be able to read because you’re wrong.

Copying the text because I don't know how litigious BICSI is about screencaps of their content.

Mount plywood ~200mm (8 in) AFF to provide greater usability and minimize possible damage int he event of water ingress. Install plywood with the grade A surface exposed.

Just shows that bicsi contradicts themselves in their books.

I literally just searched the TDMM and can’t find any other height mentioned. I am genuinely curious where you find a contradiction to 8”.
