It depends on how much electricity you plan to use in your garage. If you only need one or two lights and three or four outlets that will be used to power a vacuum or a single power tool, you probably only need a 15 amp circuit breaker. If you plan to run more than one tool simultaneously or if you have a freezer or something else that draws a lot of power on a continuous basis, you would be better off putting your heavy draw appliances on a separate 15 amp circut or getting a 20-30 amp circuit breaker.

∙ 13y agoYour question really depends on your local codes and what exactly you are wiring. With out know your local codes, all I can suggest is that you either do some research for your city, county, and state codes, which should be similar to the National Electric Code, or hire an electrician to plan it for you.

∙ 11y agoElectric garage heaters come in several sizes. A 1500 Watt 120 volt plug in heater would need a 15 amp circuit with 14 gauge wire for temporary use. A 5000 watt 240 volt heater would need a dedicated 25 amp circuit breaker and a 10 gauge wire. Every home is different and this is intended as a general reference only. Seek competent professional advice for your specific application.

Installing a 120volt appliance what breaker is needed at the electric box?
Need to know what the wattage or the amperage is of the appliance. The load amperage is what governs the wire size and the breaker to protect the circuit.
How much loss from power pole to 200 amp breaker box then off 400 feet then split at a pump house then another 30 feet to a 100 amp breaker box?
For an accurate calculation it will be necessary to know what the size of breaker exists in the pump house and what size conductors are used. Power loss is measured using actual amps required, not size of the circuit involved. But the size of circuit (breaker size) can be used. Voltage must also be known.
What size wire is best to run for a breaker box piggy back from another breaker box?
The wire is sized to the breaker in the main box that is feeding the subpanel. The calculations for the subpanel is based on what devices will use the subpanel and an estimate of duty factors for the devices. An electrician can provide this information, or you can look on-line in the National Electric Code for estimation methods.
Can you hook a 15 amp and 20 amp breaker to a breaker box using 20 amp wire?
If the full load amps rating of the motor on the name plate is exactly 15 amps you need to use # 12 wire. If it is a longer run you may have to go up one more wire size. The breaker size you need is 30 amps.
How do you measure the voltage by looking at a breaker box in a home?
You don't. You need test equipment to measure voltage.
Do you need a main disconnect on the feeder wires running to a detached garage running from the box in the house?
Yes you do. The detached garage will either be fed with a single circuit or a sub panel. The wire feeding the garage will need to be protected and that is the purpose of the breaker (disconnect). The breaker size will be determined by the size of the wire that is used on this circuit.

Why would your power go out to your garage but not to your house and no fuses be blown?
Does the garage have a separate breaker box or fuse box inside? Is there a separate power feed for the garage? In the 70's and 80's some cities were allowing aluminum wiring INSIDE residences. If the wire from the main fuse/breaker panel is aluminum there is a real possibility that you might have a bad connection between the fuse box or breaker panel and the outlets in the garage.

How do you install lights on garage that now do not have any?
first run electric cable to garage,10-3 with ground is best,you will have to put at least a 30 amp box in garage more if running 220. if just lights and power tools on 110 then you will be fine!! in box connect red wire to proper lug in box and black wire to proper lug. run 14-2 to lghts!! you can use 12-2 also it is a heavier cable!! at house breaker box run the 10-3 cable to its own breaker in box,at least a 20amp breaker!! red and black wires go to breaker and white goes to neutral bar connect ground to ground bar or neutral bar also!! use a double pole breaker in main box.
How do you reset breaker?
Go out to your breaker box (usually in the garage or in the basement), open the cover and look down at all the switches. One or more of them has been switched off. Flip it back to its on position.
What amp breakers need to go on your outside electrical box?
The size of the breaker is determined by the smallest conductor used in the system and by the type of load being serviced.
How much loss from power pole to 200 amp breaker box then off 400 feet then split at a pump house then another 30 feet to a 100 amp breaker box?

Can a 220 Volt well motor be added to a 200 amp box or does it need its own box?
The well pump breaker is installed in two slots in your breaker box. You then run the correct size cable for the amperage of the pump to the area where the pressure tank is located. install a breaker or disconnect on the wall near the pressure tank and then connect the low pressure switch to the disconnect. Connect the pump to the low pressure switch.
Where is the headlight circuit breaker?
In the breaker box
