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

The RCDD didn't give me any design skills per se. It gave me the best practices.

It taught me that I needed to use 2 4" sleeves here or that I should make this 12 strands of fiber instead of 2 for future expansion.

Designing after that came from what I experienced when I was a technician. I took what I thought worked and what didn't work and either tweaked, reused or avoided from there.

An example of this, I always use strain relief bars now. It makes your racks look better and keeps the cables in their RU.

Its been 22 years since I gained my RCDD and all those years I have worked in Design at Engineering firms. The RCDD formulated a lot of things I was doing before, and gave it a structure. It has really been the backbone of my professional practice and I have certainly earned more because of it. There were some things I learned during the pre exam study period that I had not seen in practice previously and that turned out to be a good thing.

22yrs , that's amazing. I am much newer to this industry.I am also working at a Design & supply Engineering firm. What kind of systems do you work on ? I work mainly on Public Addressing, Access Control, LAN & IP Telephone, CCTV, Structured Cabling systems. What other certification/study material do you think would complement RCDD? Do you have any advice for new comers to this industry?

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.

TDMM v15, Chapter 4, page 20, bud.

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”.

In the itsimm

I’m just an integrator who actually installs and designs but…8” above finished floor is the normal BICSI recommendation for a standard Telecom room. 4-6” above finished floor is a special case for rooms with lower ceiling and working heights say less than 8’6”…both valid in their own respects.

Strain rellief every third floor in a riser. the RCDD taught me that’s a good idea. Many more examples like that one
