What is an isolated ground plug?
Isolated ground receptacles have special construction and wiring that help eliminate electromagnetic “noise” that can affect sensitive electronic equipment. They are very rarely installed in homes but sometimes are used in large installations to combat noise interference with audio, video, and computer equipment.
Can I use an isolated ground receptacle?
An isolated ground receptacle (IGR) can reduce electrical noise, but if installed incorrectly, it can create a dangerous installation. This receptacle differs in construction from its self-grounding counterpart.
Where are isolated ground receptacles required?
The National Electrical Code does not require an isolated ground receptacle in any particular place. However, an industry regulation or engineering plan might specify them. An example would be in healthcare facilities. An isolated ground receptacle should be used for medical diagnostics equipment, for example.
How do you wire a L6 30R?
Hold the NEMA L6-30R receptacle and view the terminal screws behind it. Wrap the red wire clockwise around the brass terminal screw; tighten the connection with a screwdriver. Wrap the black wire clockwise around the brass terminal screw; tighten the connection.
Why do you use isolated ground?
The Isolated Ground (IG) is a type of equipment ground that, in theory, reduces interference experienced by electronics and instrumentation from radio frequency (RF) noise, by connecting that equipment directly to the grounding terminal of the service equipment, without ever making contact with another metal component …
Why do you need isolated ground?
The primary reason for the use of an isolated ground circuit is to provide a noise-free ground reference for the connected equipment by having an equipment ground path that is separate from the other equipment grounding (EG) means within the facility.
What is L6 30R?
30-Amp 250-Volt NEMA L6-30R Flush Mounting Locking Industrial Grade Receptacle.
How do you wire an isolated ground outlet?
Isolated Ground Receptacles must be mounted in a grounded metal wallbox. Connect bare copper ground wire (if present) to the metal wallbox. Connect the GREEN wire lead of the GFCI to the insulated Isolated Ground wire in the wallbox.
What is an isolated neutral?
A power sytem with isolated neutral (Figure 1) is defined as a power system in which the neutral points of transformers and generators are either not connected to earth or only connected to earth through measurement and protective devices with a very high impedance or through an overvoltage protector.
What is a NEMA L6 30?
The NEMA L6-30 is used for input on the domestic APC Matrix-UPS, Smart-UPS T models, and Symmetra RM 2-6kva UPS. The NEMA L6-30 receptacle is also used as an output receptacle for supplying 208 VAC in the Matrix-UPS, the Smart-UPS T models, and single phase Symmetra systems (Power Array, RM, LX).
