What is the proper height to mount a receptacle in a basement in Canada building code?
The is no height stated in the CEC as to height of receptacles. If the basement walls are studded out, then install the receptacles at the normal 300 mm above the floor.
Does the code state how many receptacles are allowed on a 20 amp circuit?
Answer for USA, Canada and countries running a 60 Hz supply service.Allow for 1 amp per receptacle and then load the circuit to 80% of maximum.In the US and in every building except homes, code limits you to 13 receptacles per 20 amp circuit. In a home there is no limit because it is assumed that even if you put a receptacle on every stud, you couldn't possibly use them all.Further informationIn the United States in non-dwellings a circuit is limited to the number of receptacles a circuit can handle, calculating 180watts per duplex. This places a 13 receptacle limit on 20 amp / 120v circuits and a 10 receptacle limit on 15 amp / 120v circuits.In dwellings there is no limit on the number of receptacles that may be placed on one circuit since it is highly improbable that you could overload a residential circuit under normal circumstances.In dwelling kitchens, while there is still no limit in the number of receptacles, there is a requirement that counter tops be served by AT LEAST 2 SMALL APPLIANCE CIRCUITS RATED 20 AMPS.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
What is an isolated ground?
When devices are grounded in most electrical system the grounds are combined without order or separation. The same ground that connects the metal box, the yoke of the electrical device and other devices is the same ground that is used at each outlet. This rarely causes any sort of problem except for sensitive electronics such as hospital equipment, high end computers and high end musical equipment. In an isolated grounded receptacle the ground wire is insulated and comes directly from the panel to the ground connection of the receptacle. This type of grounding should produce less electrical noise on the system.
What causes reversed polarity in a 110 volt receptacles?
Reversed polarity in a 110-volt receptacle usually occurs when the hot and neutral wires are connected to the wrong terminals. This can happen due to incorrect wiring during installation, loose connections, or faulty outlets. It can be hazardous because it can lead to electrical shocks and damage to appliances or devices plugged into the outlet.
Can you connect two fans and six outlets to one 20 amp breaker?
No, the six outlets are not amperage rated to be connected to a 20 amp circuit. A normal 15 amp receptacle can not be protected by a 20 amp breaker. Change the 20 amp breaker to a 15 amp breaker. This combination will pass code regulations. =============== In the United States, in a home, you can connect two hard-wired (not cord and plug connected) fans and six receptacles (outlets) to a single 20 amp circuit provided the 2 fans do not draw more than 10 amps together. If they are cord and plug connected, this limitation on the fans does not apply. In commercial and industrial installations, power to hard-wired equipment is provided on different circuits than receptacles.
Which wire goes on the ground fault receptacle?
In normal home wiring the black and white supply the circuit voltage. The green conductor connects to the green screw. The black conductor connects to the brass coloured screw and the white conductor connects to the silver coloured screw. There are additional terminals on the receptacle that connect to the down stream side of the circuit. By making these connections on the GFI receptacle all downstream normal duplex receptacles are also protected.

Why do some people remove the third part of a 3 wire AC power cord?
This action was done in the past but not so much now. It was a case of the manufacturer installing a grounding pin in their cords while homes were still using two blade receptacles. Prior to new homes having to install a grounding receptacle, homes were wired with only two slot receptacles. These two slot receptacles just had a "hot" and neutral connection for 120 volt output supply and no accommodation for the grounding of the receptacle. The new three pin extension cords would not fit into the two blade receptacles because of the grounding pin so the home owner cut off or pulled the pin out of the plug in end of the cord. Now everything is back to normal with conversions being made from two blade to three blade receptacles. In new home installations for the past fifty years it has been mandatory to use the three blade grounding receptacles.
How many volts come out of a average outlet?
Voltage does not come out of an average home outlet under normal circumstances.In North America the common potential voltage is 120 volts and is always at the receptacle as long as the circuit is energized. When an electrical device is plugged into the receptacle, through the device's connected cord, this brings the potential supply voltage to the electrical device.When the device is turned on a current (amperage) will flow, governed by the resistance of the device. If it is a lamp, it will become bright. If it is a radio you will hear sounds.When you unplug the electrical device from the receptacle, the device will stop operating but the voltage potential will still remain on the "hot" side of the receptacle's blade contact point.
How many receptacles can you wire to a 15 amp?
One View:In USA: As many as you want. There's no magic number. You have 15A to play with, so you can divide that up however you wish. It all depends on what you intend to plug in. For general usage I'd stick with the NEC Code (any point along a wall must be within 6ft of a receptacle). In my 1970's house here I've counted 9 receptacles on a single 15A breaker (yuck!).Always be sure to switch off the breakers at the main panel before you attempt to do any work on any mains power circuit.Another View:Yes there are some "magic numbers".The U.S. National Electrical Code Article 220.3 (B) (9) has guidelines for calculatiing general 120 volt dwelling-unit receptacle circuits as having a load of 180 volt-amps per receptacle. Because a normal circuit breaker can only be loaded to 80 percent of trip rating, then 0.80 X 15 = 12 Amps. 12 Amps X 120 volts = 1440 Volt-Amps per 15-Amp circuit. 1440 VA / 180 VA per receptacle = 8 duplex receptacles per circuit allowed.For a 20-Amp circuit, you are allowed (.8 x 20 X 120)/ 180 = up to 10 duplex receptacles per circuit.Another View:Both answers are technically correct. A device (receptacle, switch etc) by definition does not consume any energy so there is no load added to the circuit by installing any number of receptacles. The problem occurs when too many loads are plugged into those receptacles.The NEC section quoted above (moved to 220.14 (I) in 2008) does not apply to receptacles used for general illumination in a dwelling (which covers a majority of household receptacles). Dwellings are addressed by NEC 220.14 (J).Further, the 80% quoted is true for continuous loads only. If the appliances being switched on and off on a particular circuit never run continuously all at the same time, their individual wattages when totalled-up can, in fact exceed that 80% figure, because a non-continuously-loaded breaker may have 100% of its rating applied to it for short periods such that it does not become "warm"...A good guideline many electricians follow as a 'rule of thumb' is of 1.5 amps per receptacle.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Can a gfci get weak and trip from over load?
First, lets say this: GFCI stands for Ground-Fault Circuit Interupter. This is NOT an over-current device, and NOT an over-load device. This device stop the flow at 6mA (6/1000 of an amp) of leakage current - current leaking to ground from either the hot or neutral wire. Do you mean a GFCI breaker or a GFCI receptacle?? GFCI receptacles do not "trip on overload". Period. The only over-current protection on a receptacle is provided by the circuit breaker protecting that branch circuit. GFCI breakers are ALSO over-current devices just like normal breakers. And yes, they DO get weak, just like standard breakers do from repeated tripping. They basically have a metal strip inside that gets bent and straightened each time you trip & reset the breaker. All metal gets weak when it gets bent & straightened repeatedly. It is called "metal fatigue".
How do you wire two electrical recepticles in one box?
A switched duplex receptacle can be wired two ways. If both duplexes are to be switched then the receptacle is wired the same as any light fixture. The black wire from the bottom of the existing switch goes to the brass screw on the receptacle that is to be switched. The white wire terminates on the neutral silver coloured screw. If you want just half of the duplex receptacle to be switched then the tie bar between the two brass screws on the receptacle has to be removed. Just wiggle it until it breaks free. Usually on a half switched receptacle the top half is switched and the bottom half remains a normal connection. After removing the tie bar, the top half of the receptacle is wired the same, as the description above, for a full duplex switched receptacle. Questions use the discuss question page.
When an isolated ground is required does this mean a separate ground uninterupted from the main service panel or can you take separate grounds to the outlets that require isolated grounds from a sub p?
Answer for USA, Canada and countries running a 60 Hertz supply service.An isolated ground return to the panel means that the wire used for the isolated ground must have insulation on it. This is so that the isolated ground does not touch any adjacent metallic parts of the electrical system until it is placed on the ground block in the distribution panel. On isolated ground receptacles this is accomplished by using a three wire feeder. Black and white wires used as normal receptacle connections. The red wire with a green identifier tape installed to the isolated ground terminal of the receptacle and the bare ground wire to the green frame screw of the isolated ground receptacle.
