Section 1.0 – Preface
Nederman S‐Filters utilize high‐efficiency induction motors that have a high startup current, known as “Inrush
Current”, that lasts for a brief period, usually less‐than 10‐seconds. When the motor first starts, it will
experience up to 8x the FLA of the motor current. This will decrease rapidly until the motor reaches steady
state. If the motor does not turn over, please see Section 4.0 Troubleshooting.
There are specific electrical codes and standards outlined within this manual that need to be employed when
making the electrical connections.
Failure to adhere to the procedures outlined in this document WILL VOID the Nederman product warranty.
Section 2.0 – Circuit Sizing
Refer to Table 1 and 2, 1 and 3 ‐ Phase S ‐ Filter Motor Circuit Sizing Tables, to appropriately size the branch circuit
conductors and circuit breaker size. The data in this table is based on the 2020 NEC and is to be used as
recommendations only . Final discretion is the responsibility of the Licensed Electrician, local codes,
regulations, and the AHJ.
Due to the inrush current, the fusing/breaker must be sized larger to protect the wiring in the event of a short‐
circuit. The motor-overhead, not the breaker, provides the motor protection and should be set as close to the
FLA (Full‐Load Amperage) of the motor as possible to maximize motor protection.
The minimum conductor size listed in the table is calculated based on 75°C wire. If using a different type of
wire, or the dust collector is located a significant distance from the main panel, the wire size must be adjusted
accordingly.
Note: AWG #12 is the minimum acceptable wire size

Section 2.0 – Circuit Sizing
1 Techtop motor nameplate full‐load amps (Used for setting overload only).
2 Minimum size based on 75ᵒC (167ᵒF) insulation and copper wire, such as RHW, THHW, THW, THWN, XHHW,
XHWN,USE, ZW. Verify with table 310.16. Conductor size may need to be increased based on wire type, length
and/or run.
3 Branch circuit protection to be sized at 250% of motor FLC for (Inverse Time) circuit breaker based on tables
430.52, 430.248, and 430.250. Based on 2020 NEC 70 Article 430 and best‐practice.
4 Branch circuit protection to be sized at 175% motor FLC for Dual Element (Time‐Delay) Fuse based on tables
430.52, 430.248, and 430.250. Based on 2020 NEC 70 Article 430 and best‐practice.
5 Branch circuit protection to be sized at 300% motor FLC for Nontime‐Delay fuse (Class CC fuses) on tables
430.52, 430.248, and 430.250. Based on 2020 NEC 70 Article 430 and best‐practice.
6 Recommended setting for overload on Nederman Push Button Starters based on motor nameplate multiplied by
service factor.
7 Wire‐nuts or soldering are
NOT acceptable means to connect motor leads per NFPA 79, 13.5.9. Use appropriate
components to make motor connections such as split bolts, crimp‐connections and eye‐bolts.
8 It is the responsibility of the end‐user to follow State and Local Codes. This chart is provided as a helpful
resource only. Use of a qualified and licensed industrial electrician is required for proper installation.

Section 2.0 – Circuit Sizing
Product Owner/End-user shall provide branch circuit protection. Refer to the Motor Circuit Sizing Tables on
previous pages for max breaker and fuse sizes.
*Note: F1 represents fuses. An Inverse Time Breaker would replace the fuses (F1) in the below example.
