Subject: SMP motor wiring inspected by electrician 

The AC wiring for the SMP motor was inspected by Randy Boehm (TRIUMF electrician) as recommended by Franco Mammarella (TRIUMF electrical engineer).  After inspecting the system Randy required the following changes:

  1. AC wiring inside the control panel be increased to 16awg minimum (14awg preferred)
  2. Wiring between the control panel and motor control box be increased to 14awg
  3. Power cable to the motor be increased to 14awg
  4. Current rating for MS connectors be checked and replaced if below 10A
  5. Prefer that motor control box components be relocated to the control panel to reduce number of AC wires and connections (preferred but not mandatory)
  6. A dedicated ground wire is required in the cable going to the motor (if not already in place)

After these changes have been made the inspection will be repeated.

 

July 31, 2019 update:

Items 1, 2, 3, and 6 from above were completed.  14awg wiring was used for wiring inside the control panel (Item 1).  Current rating for the MS connectors was checked and is over 10A (Item 4).  Motor control box components were not relocated to the control panel at this time (Item 5).

Randy repeated his inspection today, and approved of the updated 120V wiring.
