The tank and cherry stained
stand arrived on Novmber 7, 2003. My first goal was to design and create an
electrical control system that was easy and safe for the family to use.
The design criteria were to co-locate all the power receptacles in one location
away from the sump in the stand and provide an easily accessed electrical switching
panel to permit convenient control of all the system's electrical components.
Before I could really
start I needed an accurate,
scaled drawing of the entire setup as well as an electrical schematic to layout the
wiring for all the components. The two graphics were created to assist me
in the layout and design of all the components and structure I needed to complete
the setup. Note: The final complete configuration is slightly different than
what is on the drawings since I had to make a few adjustments during construction.
First, I needed to select a electrical switch panel
before I could accurately design the layout. I began a search at Reef Central for switch panel ideas and came
across a thread where another reefer was using American DJ PC-100A Power Centers
(Front, Back) for
his control panels and I knew right away they were perfect for our setup!
Now that I had a design, the stand, and the components needed, I began the mod.
Step 1: Design and create
the support structure for the American DJ Power Centers and mount them in the stand.
I started with 3/4" hardwood plywood (red oak)
since I wanted all the additional structure to "look" like the original
stand. After building a support frame, I installed it in place for a
trial fit to see if it would allow room for the switches to fit squarely
within the door opening... and it fit like it belonged
there!
Step 2: Design and build
the support panel for the ten standard household 15 amp receptacles and mount it
into the stand.
Again I used all hardwood plywood (red oak) for
construction of the panel and it's support structure. Refering to my PaintShop
Pro graphic (linked above), I knew the general dimensions for the panel and the
basic arrangement of the receptacles. First I layed out the panel and
dimensioned it for cutting. Then, after designing and building
a support structure for the panel, I installed it into the stand (Pic
1, Pic 2) to check for proper fit and
that it was positioned properly for accessibility and adequate spacing for the plumbing.
Note the raised plywood channel installed on the bottom of the stand from front
to back and attached to the electrical panel vertical support structure. This
is the bottom guide for the plexiglas barrier I made to keep water from splashing
from the sump onto the electrical components.
Once the basic panel and support structure were
completed, I arranged the receptacles on the panel, marked their locations, and
screwed them in place (Pic 1,
Pic 2). Once completed, I installed the entire setup and verified everything
was positioned well. Now that I was satisfied that all the support structures
were completed and positioned well, I disassembled everything and applied a
couple coats of stain. Here are a couple, shots (Pic
1, Pic 2, Pic 3)
of all the support structure completely stained and installed, ready for wiring.
Step 3: Install all the wiring
from the power centers to the receptacles, including the timer receptacles.
At this stage I was interested
in two things; esthetics and safety. I wanted to be certain all the electrical
wiring was routed out of the way to the extent possible so it couldn't inadvertently
get snagged when working in the stand as well as totally away from any source of
water. Due to the proximity of plumbing immediately behind the receptacle
panel I wanted to be certain the wire bundles were routed away from potential problems
down the road.
Part of my design criteria
was to match the location of a receptacle on the electrical panel inline as close
as possible with it's respective switch on the power centers (PCs).
That's to say that the top power center aligns with the top row of receptacles and
the LH PC switch aligns with the top row LH receptacle, and so on. That said,
I started by working from the longest wire runs down to the shortest, i.e., I started
wiring the lower row of receptacles moving from left to right (Pic1,
Pic2). I'd first take a long piece of wire
and lay it out from the PC location around the right side of the stand and over
to the receptacle. Once I was happy with the length I'd cut equal lengths
of the 14 guage stranded black, green and white wire. I then installed the
Leviton plug on one end and wired the other end to the receptacle. At this
point I needed to be certain which receptacles were joined (both outlets working
in parallel) or separated so I knew which brass tabs to snip off (Pic1,
Pic2).
Once all the receptacle
wire runs were completed, including the three timer receptacles on the right
side of the stand, I was ready to do the final routing and bundling (Pic1,
Pic2, Pic3).
I used plenty of wire wraps to make the bundles tight and secure.
Step 4:
Perform operational checkout of electrical panel and power centers.
Now that everything was
connected I plugged the power centers in and tested each outlet to see if they were
powered and wired correctly. Fortunately everything was OK and I didn't have
to do any rework.
Although this piece of
the project took me a while to complete it was very satisfying since I'd never done
anything like it before. I just goes to show that desire coupled with access
to helpful information can lead to great success. And I would be remiss if I didn't
give glory to my Lord and Savior, Jesus Christ! This entire project is an
act of worship for me... a way to express my love for the Lord by using the gifts
and talents He gave me to bring glory to His name! He guided me along this
path as a way to bring my family closer together and for that I praise Him!
