Best Answer

The main breaker is at the top/center of the panel and should have a number on it. Usually 100 amp panels are used in homes because they are cheaper than 200 amp panels, and 100 amps is usually sufficient current to supply a home.

If you plan to add any thing(s) that will draw much more current than an average home (machine shop, arc welder, etc.), you should look into upgrading the panel. Overloading a panel is asking for an electrical fire.

How can you tell if the wires in your home are copper or aluminium?

Shut the main breaker off on your distribution panel. Remove the cover. Look at the colour of the wires that are connected to the breakers. If they are silver in colour then they are aluminum wires. If they are copper in colour then they are copper wires. Replace the panel cover and turn the main breaker back on.


Every time I run my dryer 240v 10 -15 minutes later the main power breaker trips why?

If your main breaker is tripping you may have big issues! Don't use your dryer until you've contacted an electrician. Your panel may be overloaded when the dryer is on. The electrical panel in your home could becoming too small for all of your appliances. On a 100 amp service, if many of your high current drawing appliances are on at once this condition could happen. With the dryer and hot water tank on you will be drawing about 40 amps. Putting the stove with an oven on at the same time will boost your consumption up to about 80 amps. With a couple of smaller 1200 watt appliances on you are just about at your limit. Call an electrician and get him to do a load test on your panel, this will tell you what the problem is right away. Don't be surprised if the recommendation is to upgrade to a 150 or 200 amp panel. In most homes today the recommended panel board is 200 amp 42 circuit .


How many amps to run a 50 watt bulb?

At what voltage? Until you tell me the voltage I can't give you an answer. To find out Amps you need to divide the Watts by the Volts. At 120V you have 0.4 amps. At 12V you have 4 amps.


How do you tell a single pole breaker from a double pole breaker?

A single pole breaker will take up one single slot in a household distribution panel. A two pole breaker will take up two slots in the distribution panel. Older double pole breaker installations had two breakers side by side with the two switch handles physically tied together. Today two pole breakers are one unit containing two output terminals for the output circuit. This new configuration has only one handle to operate both sides of the breaker for shutting the circuit off and resetting a tripped breaker.


How many amps are in 8000 watts?

WATTS = Volts x Amps For me to tell you what kind of amperage you're dealing with you'd have to tell me what voltage you're using. Or you could simply do the math yourself. Simply divide the watts by the volts and you'll get amps.

How do you tell the meter amperage of your homes electric meter?

Your main breaker should tell you the amps of your panel.


How many breaker amps will a 200 amp service with no main breaker support?

Check the nameplate on the service panel. There it will tell you what the buss capacity is. On a 200 amp service nothing in the wiring configuration is allowed to be less than that the service rating. In the market there are 200 amp 42 circuit distribution panels.


What size amp circuit breaker should be used for a dishwasher?

There is a rating plate on the dishwasher that will tell you how much current it draws. A typical breaker would be 20 amps with 12 AWG wire.


How do you tell if its 60 or 100 amp service?

Look at the main breaker or fuse at top of main panel and see if it is labeled 60 or 100.


How can you tell what the amp service is in your house?

I would have to say that the amperage label on the main breaker would designate the amount of amps coming into the house.Look at the number on the handle of the main breaker. That number is the rating of the breaker and at what amperage the breaker will trip. If you have a main fuse switch the number on the fuse is the tripping amperage. This will be the amount of current that the service is rated at.


What formula do you use to tell if you'll overload a breaker?

Use the Watts = Amps x Volts formula. Most appliances will have the wattage on the nameplate. Nameplates that have the amperage on them will be the size of the breaker that should protect that device. There is an exception for motor loads, breaker size is 250% of full load amps. Divide the watts by the voltage and you will get the amperage of the device. This amperage will govern the size of the breaker to use. Breakers start at 15A, then 20A,30A,and 40A for most branch circuits in a house.

How many watts are in 30 amps?

There is no way to tell, you don't have enough information. Watts are what you get by multiplying the amps x the voltage. Simply put, Volts X Amps = Watts.
