A 30-A outlet would be for a specialized installation, such as for a welder or other high-wattage device. You would typically have a single outlet, although you could certainly have multiple outlets for convenience, as long as there were procedures to prohibit use of more than one at a time.

Under no circumstances should any HOUSEHOLD receptacles (15 or 20-Amp) be installed on any branch protected by a 30-amp breaker, as this would cause a fire and electrocution hazard.

15 amps x120 volts =1800 watts. NEC requires you not exceed 60% of the load. Therefore 1800 x .60 =1080. 1080 watts divided by 120 volts = 9. You can safely install 9 outlets on each 15 amp circuit but no more. This is assuming only those 9 outlets will be on the circuit and no lights.

You should install no more than 9 outlets. If you add a 75 watt light then install no more than 8 outlets and that 1 light.

How many 50 watt lights on a 15 amp circuit?

50 watt equals less than 1/2 amp current flow at 120 volts so you can have 30 light on a 15amp breaker or 40 on a twenty amp breaker.


How many eletrcal outlets can you have in a garage?

There is no limit as to the amount of circuits you can have in a garage. If you mean how many devices on a 15 amp single circuit breaker then the answer is 12. Be sure to total in light fixture outlets and switch boxes.


How many outlets are allowed on a 240 v branch circuit?

Branch circuit loading In Canada the CEC states that there shall be not more than 12 outlets on any 2-wire branch circuit. These outlets shall be considered to be rated at not less than 1 amp per outlet Where the connected load is known, the number of outlets shall be permitted to exceed 12, provided that the load current does not exceed 80% of the rating of the over current device protecting the circuit. For example on a 15 amp breaker, 15 x 80% = 12 amps, hence the standard of 12 outlets on any 2-wire branch circuit. On a 20 amp breaker, 20 x 80% = 16 amps. So from a 20 amp breaker this allows 16 outlets on a 2-wire branch circuit as long as the outlets are not considered to be rated at less than 1 amp per outlet. The definition of an outlet is a point in the wiring installation at which current is taken to supply utilization equipment. What this means is that if a light switch and a fixture outlet were on the same 2-wire branch circuit they would be subtracted from the maximum count of 12 receptacle outlets on the circuit which would leave 10. If the light fixture draws 3 amps plus the switch outlet, then the total circuit outlet count would be reduced to 8 receptacle outlets (12 -- 3 -- 1 = 8). On a standard specification home most electricians will wire one circuit per room, the outlet count usually never reaches the maximum of 12 outlets.


How many outlets can you have on one circuit?

Depends on what the outlets are controlling, size of the wire, and size of the breaker.


What are the electrical codes covering - wiring a new garage?

Depends on what you are asking about. I can tell you that all garage outlets must be protected by a GFCI circuit. You can install as many or as little as you want as long as there is at least 1 outlet on each wall. Any freezer or refrigerator must be on a dedicated circuit. There must be a light switch by the doorway mounted 48" to the top of the switch box. If you have 2 entrances into the garage then install a 3 way light switch so the lights can be turned on/off at both locations. Outlets cannot me mounted higher than 48" above the floor. I would install the outlets on 1 circuit and the lights on another circuit unless you only have a couple of lights. Use AWG #12 wire for the garage protected by a 20 amp breaker. If the garage is detached from the house then you need a disconnect in the garage. Any 240 volt outlet must be on a dedicated circuit protected by the proper breaker and correct size wire needed for the device.

Christmas light are causing the 15amp circuit breaker to trip and Circuit Panel is full Can I upgrade to a twin circuit breaker without installing a subpanel?

Your only hope is that someone wired the box not to code and that there are two wires going into the offending breaker. If you can't separate wires you can't distribute the load.

What do I do if there is no circuit breaker for outdoor light?

If you have a light that is not being powered through a circuit breaker or fuse, you should call a qualified electrician to remove this circuit from the panel's bus and install a circuit breaker for it. Without an overcurrent protective device (circuit breaker or fuse) you have a potential fire hazard.


How many outlets and lights on a 60 amp breaker?

120 amps The above answer is wrong. A 60 amp breaker is designed to trip at 60 amps be it a single pole, double pole or a triple pole that is used on three phase equipment. The number on the handle of a breaker is the trip capacity.


What does the red light on the gfci outlet mean?

It means the breaker has been tripped. There are two possible ways to reset it - some have a button on the outlet (there may be several outlets on one circuit, so you may have to look around) the other is the main breaker in your breaker box. You'll need to find a reset the breaker.


What size amp circuit breaker should be used for a pool light?

The pool light is usually on a 15 amp circuit. The breaker feeding this circuit must have a GFCI rating.


Why power circuits and lighting circuits require a separate circuit breaker?

Utility outlets and lighting outlets should be separate so that when a utilization device plugged into an outlet trips the breaker or blows the fuse, you won't be left trying to find your way to safety in the dark. Light fixtures are much less likely to trip a breaker in ordinary use, but there are places you also want more than one lighting circuit for illumination.


Parking lights will not turn off is it a relay or circuit breaker?

It is a relay or switch problem. A circuit breaker or fuse won't keep a light on.


Why would all three outlets in a bedroom and the bathroom light lose power even if the breaker is reset?

Wires could be disconnected from the main fuse box. Check to see if you have any Ground Fault Outlets installed and ensure that all have been reset. It sounds like they may all be on one circuit and if so, You need to check that all outlets nad light fixtures have good connections and are tight. Its possible that you have a GFI outlet in bathroom that is tripped or is bad the bedroom outlets are possibly wired to same circuit It just may be that the fault that tripped the breaker also broke the circuit to the other points. Look into the boxes of the outlets and switches. If there was a fault you may see carbon where an arc broke a wire to the remaining points in the string.


If there are a series of outlets and switches that won't operate in one particular area of your home and there are no breaker switches thrown in the breaker box what else could be causing this problem?

When several outlets are on the same circuit the current comes first from the breaker panel to one outlet where it is connected to a duplex receptacle and/or switch or light, then to the NEXT outlet, light or switch. If a connection was not made properly at any point along the way it can corrode or somehow loose connection back to the breaker panel. If that happens, every outlet DOWNSTREAM will not be working properly. If you cannot track down the problem yourself, you will need to hire an electrician.
