Terminating Wires and Connectivity Test
Date: 5.15.18
Location: Logan HS
Time: 3.5 hours
Goal: Terminate wires from switches, pumps, peltiers, etc... in box and complete a connectivity check.
Students: Boy Yang, Austin, Ben and Andy
This was one of those significant work nights where we are beginning to see the end in sight. We started terminating wires into our electrical box which indicates we are not far from a test of the DM prototype.
A lot of front end work went into identifying each of the 70 wires coming down into the box. This was done with labels and masking tape. All the common wires were identifed and terminated first. Then we started work on the individual pumps and fan. We are working in "layers" putting multiple loads on each circuit breaker. For example, on one 10 amp breaker we will have the evaporator tank pump, and evaporator peltier all tied into the same breaker. All total they do not exceed the 10 amp draw. This will save us some time and space.
We had two people organizing wires, cutting, stripping the wire and then crimping a fork onto the wire to secure to the bus or terminal strip. It was very tedious work, but at the end of the night, we energized the circuits we completed and we did have connectivity.
We will do another work night on Thursday to finish the job.
