The
Problem of Electromagnetic Interference
Reduction of electromagnetic interference (EMI) in the electrical grounding system is
essential for proper operation of many types of electronic equipment. In conventional
grounding circuits, the conduit system is used as the grounding path. The conduit system
is grounded at the service entrance and connected to intervening sub-panels, structural
steel, and other grounded equipment. Although this will provide personnel and equipment
protection, the entire conduit system becomes a large antenna which collects EMI (i.e.,
electrical noise) and transmits it throughout the grounding system. Whenever that occurs,
the signals may adversely affect the performance of personal and small business computers,
electronic testing and calibration equipment, and solid-state cash registers.
The Pass & Seymour/Legrand
®
Solution
By running an insulated equipment grounding conductor directly to the neutral at the
service entrance, and installing Pass & Seymour/Legrand Isolated Ground Receptacles,
you effectively isolate the grounding circuit from the conduit grounding system. This
significantly reduces the size of the antenna and limits the amount of EMI that can
be picked up in the isolated grounding system. This provides a relatively noise-free
grounding path and improves the operation of electronic equipment.

Section 250-146(d) Isolated Receptacles.
Where installed for the reduction of electrical noise (electromagnetic interference) on the grounding circuit, a receptacle
in which the grounding terminal is purposely insulated from the receptacle mounting means shall be permitted. The
receptacle grounding terminal shall be connected to an insulated equipment grounding conductor run with the circuit
conductors. This equipment grounding conductor shall be permitted to pass through one or more panelboards without a
connection to the panelboard grounding terminal bar as permitted in Section 408.40, Exception, so as to terminate within
the same building or structure directly at an equipment grounding conductor terminal of the applicable derived system or
service. Where installed in accordance with the provisions of this section, this equipment grounding conductor shall also
be permitted to pass through boxes, wireways, or other enclosures without being connected to such enclosures.

Section 406-2(d) Isolated Ground Receptacles.
Receptacles incorporating an isolated grounding conductor connection intended for the reduction of electrical noise
(electromagnetic interference) as permitted in Section 250-146(d), shall be identified by an orange triangle located on the
face of the receptacle.
