Blade Receptacle Chart

“Twist-Lock” remains a registered trademark of Hubbell Incorporated. This term is widely used generically by the electrical trades to refer to NEMA locking connectors manufactured by any company. Locking connectors use curved blades. Once pushed into the receptacle, the plug is twisted and its now-rotated blades latch into the receptacle. To unlatch the plug, the rotation is reversed. The locking coupling makes for a more reliable connection in commercial and industrial settings, where vibration or incidental impact could disconnect a non-locking connector.

Replacements for: electrical receptacle, high voltage receptacles, costs for standard receptacles, locations by code for GFI receptacles, A typical property will have several types of electrical receptacles. Although the majority of them are for standard use, some may be designed to accept certain kinds of plugs and fulfill a specific purpose. Standard receptacles are usually rated at 125 volts, 15 or 20 amps.
Higher voltage receptacles and higher amperage receptacles are required for a specific use (and can also be know as "dedicated receptacles"). These specific use receptacles are needed to provide power to larger appliances, air conditioners, electric dryers, commercial equipment, etc. Their slots have distinctive shapes that will not accept a standard plug rated for 125 volts. The wiring and circuit breaker that supplies the power to them must also match the specific use.
Standard Receptacles
High-Voltage Receptacles
GFI Receptacles
Tamper Resistant Receptacle
GFI receptacles always have a test and reset button. Although they are meant for standard use, they are required by code for areas that may be hazardous. They should always be found in locations where one could come in contact with water such as: bathroom, kitchen, outside, basement, etc. This is because they are meant to shut down immediately before you can get an electric shock from the item plugged in. Press your test your button to be sure!

Information about Electrical Receptacles:
When you need an Electrician.


 
STEP 1. Be sure the power is turned off to that circuit (or shut all power off).
STEP 2. To begin removing the existing device(s), remove the wall plate and test for voltage first. Then remove the two mounting screws and pull the existing device forward as far as the wires will reach.
STEP 3. Take notice of all the wiring connections to the existing device before removing them (colored wires, screw connections, wire nut connections, etc). Also take notice of the colored screws (dark, silver, brass, green, etc.). Correct wiring is very important! Then cut the wires off close to the device or loosen the screws to remove the wires. Other wires in the outlet box do not matter and should be left alone.
NOTE - If the existing wires have an insulation cover that is crumbling apart, an electrician should be brought in to complete this job!
STEP 4. Make the wiring connections to the new device. Strip the wire insulation back 1/2" to 3/4". Wire always wraps around a screw clockwise. Dimmer wires should be connected with spring insert type wire nuts. Make sure all connections are tight! (More trouble calls are due to loose connections than any other reason). Wrapping electrical tape around the device to cover the screws can be a good idea. It can provide temporary safety if the cover plate is to remain off during a painting or wall repair job.
 

Some Helpful Tips

  • 3-way switch - odd color screw wire (from old device) to odd color screw (on new device) the other two wires do not matter.
  • Standard dimmer - wire colors do not matter (unless it's a 3-way dimmer).
  • Standard switch - wire colors do not matter.
  • Standard receptacle - light colored screws connect to the white wire(s), dark colored screws connect to the black wire(s).
  • G.F.I. Receptacle - same as a standard receptacle but watch out for the "load" connection (input power does not get connected to the load or output side of a G.F.I. receptacle).
STEP 5. Grounding a device properly is your responsibility. Metal boxes should be grounded and devices should be grounded (your voltage tester will be used to test the ground when the power is turned back on).
STEP 6. Folding the wires back into the wall outlet box should be done with care. Some wall outlet boxes may lack space due to other wires and other wire nuts. Also take notice that the ground wire does not come close to any screws on a switch or receptacle (instant short circuit). Make sure that the device can freely touch the wall surface (top & bottom) without crushing the wires inside.
STEP 7. Install the two screws and turn the power on. Test the device for polarity and grounding with your voltage tester (the voltage should be the same from "hot to ground as neutral to ground). Install the wall plate.

C.  When you need an electrician.
         A handy person can usually perform some of the simple electrical jobs. We want to stress the importance that all electrical jobs must be done mechanically correct and according to the local codes. Incorrect electrical work is very common. Most folks try to save money by doing it themselves but, at the same time they may create situations that are costly to cure. We always recommend hiring a licensed electrical contractor. Here are some things you should know -
 

  • 3-way Switch - is double operation switching for lighting from two or more locations. If you confuse the wiring you may never make it work right. This is the most common error made by a non-electrician.
  • Very Old Receptacles or Switches - If the existing devices are older then yourself, you won't want to deal with them. The photos of receptacles (on the right) have very old wires inside, they are short and fragile!
  • Aluminum Wiring - All work dealing with aluminum wiring and/or cables must be performed by an electrical contractor. Please don't try it.
  • Electrical Problems - Replacing switches and/or receptacles usually will not solve electrical problems, unless you feel certain the problem is limited to that device only.
  • New Wiring Installations - Any new wiring installations and/or electrical service work should always be performed by an electrician. Your safety and property are at stake!
  • Understanding the Do-It-Yourself Instructions - If any of the instructions on this page are unclear to you - Call an electrical contractor.
