INSTALLATION
Pre-Plan your installation. You will need to accomplish the following:
▪ Meet all National and Local codes. (NEC ® Article 285 addresses SPDs)
▪ Mount SPD as close to panel or equipment as possible to keep leads short.
▪ Ensure leads are as short and straight as possible, including neutral and ground.
Consider a breaker position that is closest to the SPD and the panel’s neutral & ground.
▪ Suggested breaker & conductor size is 60A-30A with 6 AWG.
▪ Make sure system is grounded per NEC ® and clear of faults before energizing SPD.
The following options or implementations require extra consideration. See appropriate sections
within this manual:
▪ Internal or Integral Mount Installation inside electrical gear (page 5)
▪ Flush Mount Option (page 6)
▪ Retro-fit where no breaker positions are available (page 6)
▪ UL/NEMA 3R Drain Holes (page 6)
1. Use a voltmeter to check all voltages to ensure correct SPD.
2. If SPD has Dry Contact, Remote Monitoring or Remote Display, pre-plan their installation.
3. Remove power for panel. Confirm panel is deenergized.
4. Identify connection/breaker location and SPD location.
5. Make sure leads are short! Reducing inches matter! Pretend that connector leads cost you
$1000/foot to make leads short!
6. Remove an appropriately sized knockout from panel. Create an appropriately sized hole in the
SPD enclosure.
7. Mount SPD.
8. Connect conductors as appropriate – short and straight as possible
(Note that Hi-Legs are Phase B).
9. Label or mark conductors as appropriate (neutral: white, ground: green, energized:
black, hi-leg: orange).
10. Make sure system is bonded per NEC ® and is clear of hazards or faults before energizing.
(N-G bonding not per NEC ® will fail SPDs: #1 cause of SPD failures.)
11. Energize and confirm proper operation of indicators and/or options.

▪ Use closest breaker to SPD
▪ Locate SPD close to intended breaker
▪ Keep Leads Short as Possible
▪ Avoid Sharp Bends
▪ Outdoor installation requires appropriate
weather sealing at nipple (o-ring, sealing
conduit, etc.)
