Surges caused by static discharge, capacitive and inductive loads or lightning can quickly destroy sophisticated electronic equipment and components used in industrial and commercial applications. These surges cripple operations – particularly the data and communication systems that virtually every enterprise relies upon today, including UL® 508A panels with their reliance on control circuits. Also, the NEC requires a listed SPD to be installed on various equipment types including elevators on emergency systems [NEC 620.51(E)], critical operations data systems (NEC 645.18), industrial machinery with safety interlock circuits (NEC 670.6), wind electric systems [NEC 694.7(D)], fire pump controllers (NEC 695.15), emergency panelboards and switchboards (NEC 700.8) and critical operations power systems (NEC 708.20). Source switching — Smart grid, gensets, photovoltaic power systems and wind power generation, etc. * During overcurrent events, both circuit breakers and fuses can produce arc voltages 2-3 times the system voltage in accordance with the UL standards. Damage caused by transients and surges • Disruptive – A voltage transient enters an electronic component and it interprets the transient as a valid logic command, resulting in system lock-up, malfunction, faulty output or corrupted files. • Dissipative – Associated with short duration repetitive low energy level surges, resulting in equipment failure over time including electronic components, ballasts, motors and controllers, service entrance equipment, panelboards and switchgear. • Destructive – Associated with high level energy surges, resulting in immediate equipment failure including electronic components, ballasts, motors and controllers, service entrance equipment, panelboards and switchgear. We offer a wide selection of Bussmann™ series surge protection products that help assure power quality by eliminating damaging surges. Case studies and references for industrial and commercial applications • G.W. Allen and D. Segall with IBM – Two year study at over 200 locations in 25 cities – 88.5% of AC power problems are transient voltage related. • 2011 Erimar Systems Integration — A lightning strike entered the metals fabricating facility and destroyed $20,000 worth of control panels, electrical infrastructure and Cisco infrastructure. Loss of data system also cost 11 days of production. • IEEE Emerald Book and NFPA 780 both recommend using surge protection as a part of a building’s lightning protection system. Suppressors at the service entrance only reduce, but not completely eliminate, the high-energy transient. A second surge protective device must be applied upstream of critical equipment. All SPDs should comply with UL 1449 4th Edition or later. • 1999-2001 Electric Power Research Institute (EPRI) Study – Concluded downtime from power sags, surges and transients cost US industry: • $50 Billion+ in 1999 • $100 Billion+ in 2000 • $200 Billion+ in 2001 • Continues to escalate as more electronic equipment is used Internal damage — PCB destroyed by a surge Service entrance destroyed by a surge Eaton.com/bussmannseries 3 Application Note 3193 Effective March 2019 UL Type 1, 2, 3 and Type 4 component assembly, and data signal surge protective devices UL SPD types and NEC locations NEC SPD installation/connection Both UL and the NEC define surge protective device Types, but they are NOT the same.

The NEC recognizes this need and has adopted the following provisions where surge protection is required. Regardless of whether surge protection is required or not, it’s prudent to have surge protection on all circuits as many portable appliances and communications devices with sensitive electronics may be powered from circuits where transient overvoltage surge is an issue. Effective March 2019 694.7(D) “A surge protection device shall be installed between a wind electric system and any loads served by the premises electrical system.” Added in 2011, surge protective devices should be on the circuit serving the wind electric system or on the service disconnect’s loadside. 695.15 “A listed surge protection device shall be installed in or on the fire pump controller.” Added in 2017, this NEC provision requires a listed SPD to be installed in or on the fire pump controller to provide protection. A study commissioned by the Fire Protection Research Foundation found that 12% of those surveyed had surges damaging their fire pumps. Below are the major NEC Sections requiring surge protection. On page two is a selection chart for Bussmann series surge protective devices (SPD)based upon application. 620.51(E) “Where any of the disconnecting means in 620.51 has been designated as supplying an emergency system load, surge protection shall be provided.” Added in 2017, this section was added to address emergency system loads such as elevators, escalators, moving sidewalks, chairlifts and associated equipment. 700.8 “A listed SPD shall be installed in or on all emergency systems switchboards and panelboards.” Added in 2014, this requirement helps ensure emergency electrical systems continue powering vital, life-safety loads in the event of damaging surges. 645.18 “Surge protection shall be provided for Critical Operations Data Systems.” Added in 2017, Critical Operation Data Systems is defined by the NEC as “Information technology equipment systems that require continuous operation for public safety, emergency management, national security or business continuity.” 670.6 “Industrial machinery with safety interlock circuits shall have surge protection installed.” 708.20 “Surge protection devices shall be provided at all facility voltage distribution levels.” Added in 2008, Critical Operation Power Systems (COPS) are power systems that can include HVAC, fire alarms, security, communications and signaling for designated critical operations areas. Surge protection helps ensure these systems will operate as intended in an emergency situation. Added in 2017, this section was added to address the concern with safety interlock failure on machinery causing a safety risk to operators who may not be aware of disabled safety mechanisms.

Understanding the following points will help ensure that the correct surge protective device is specified for the electrical system or equipment. • Typical North American electrical systems include single-phase, split-phase, Delta and Wye. • Selecting the wrong SPD generally arises from misunderstanding the nominal system voltage, ground and neutral connections. • General convention has it that a “ground” wire is not counted as a wire in the system description (e.g., 3 wire, 4 wire, etc.), but it is counted as a connection point if the selected SPD has a ground wire. • Selection of a device voltage rating for Wye systems must be based upon its nominal system voltage rating and not on the legto-leg voltages in the Wye. • Bonded N-G configurations do not require protection at the service entrance transformer, but protection is suggested in downstream bonded N-G systems if the length of conductor making the bond is greater than 10 feet (3 m)*. The following are the BSPD, BSPA and SurgePOD PRO catalog numbers, and the electrical systems and voltages to which they can be applied along with any notes that help in understanding the context of the application. The examples show circuit breakers as the most typical means of making connections to the panel phases, although connection with fusible switches and lug connections are permitted, provided the terminals are rated for the 10 AWG conductors used by the BSPD, BSPA and SurgePOD SPDs. Note: UL does not require using overcurrent protective devices such as circuit breakers or fused switches as the SPD’s thermal disconnect technology will safely take the SPD offline in the event of a failure. Use of these devices is for facilitating connection to the panel buses and installation convenience.

At the start of this section are diagrams indicating the connection points for the Type 1 and Type 2 SPDs contained in this guide and the electrical system to which they can be connected. Installation steps 1. Inspect the electrical panelboard to be sure it is properly grounded in accordance with prevailing code requirements. 2. Inspect the SPD unit to determine: • It has the correct nominal system and MCOV voltage rating and is the correct configuration for the installation. • It is not damaged; If the unit is damaged or not correct for the system, do not install it. Secure a proper replacement before proceeding with the installation. 3. Deenergize panelboard and follow established lockout / tagout procedures. Remove panelboard cover(s) to gain access to the interior. Check to make sure the entire panelboard is deenergized before proceeding. 4. Select a location on the panelboard that accommodates mounting the SPD and allows the leads to reach their intended connection points. Be sure the SPD unit can be positioned so that the LED status indicator(s) is visible. A location that permits the shortest lead lengths is preferred. 5. Remove a 3/4” knockout or make a 1-1/16” diameter hole where the SPD is to be mounted. 6. Remove the locknut from the unit and insert leads through the panelboard wall being careful not to damage the conductor insulation. (For NEMA 4X installations, use appropriate gaskets or sealing means to retain the NEMA 4X rating on the installation — see Figure 1.) Reinstall locknut and tighten to specified torque. Installation option A: using feed through lugs 7. Determine if the lugs are rated for stranded 10 AWG conductors. If lugs are not rated for this size conductor, DO NOT install the SPD unit, or replace lugs with appropriately rated lugs before proceeding, or install the unit using installation option B. 8. Route and trim the leads so they reach their connection points with the least amount of length. 9. Strip the lead ends to lug manufacturer’s specifications, insert them into the appropriate ports and torque to the specified value NOTE: DO NOT install more than one lead into the same lug port. Go to step 13. Installation option B: circuit breaker or fused switch When using a circuit breaker or fused switch, see suggested ampacities in Table A for the SPD family product being installed. 10. Place in the OFF position and install a new, dedicated common trip circuit breaker or fusible switch with fuses sized by SPD family and located as close as possible to where the SPD unit is mounted. 11. Route and trim the leads so they reach their intended connection points with the least amount of length. 12. Strip the lead end to fit the connection points, insert into the terminal lugs and torque to the specified value. Go to step 13. Finishing the installation 13. Reinstall the panelboard cover(s). 14. Test the SPD installation by energizing the panelboard and placing the circuit breaker or fusible switch (requires fuses to be installed) in the ON position. Verify the LED status indicators are functioning according to the installed SPD model. If LEDs are not properly displaying for a correctly installed and functioning SPD (per model), see the troubleshooting procedures for possible causes and remedy. NEMA 4X installation requires appropriate customer-supplied gasket between the SPD and enclosure wall.

If using conduit, keep the run as straight and short as possible, and avoid using 90 elbows. NOTE: For optimum performance, trim the leads to the shortest length possible and avoid sharp bends. Make electrical connections appropriate for the application. 12 Eaton.com/bussmannseries Application Note 3193 UL Type 1, 2, 3 and Type 4 component assembly, and data signal surge protective devices Effective March 2019 BSPD, BSPA and SurgePOD PRO comparisons SPD model / color Product warranty* System types BSPD — grey Commercial and industrial with high surge current 10 years Delta and Wye Nominal system voltages 120/208, 240, 277/480, 480, 600 Max. continuous operating AC voltage (MCOV) [VC] Sized to nominal voltage (150 V to 840 V) 200 kA 20 kA 120, 200, 300, 400 kA 3, 5 Wires Yes
