I have a 30 amp circuit 10 ga wire in an island. I've been told that I need a 40 amp breaker on 8 ga wire which will require breaking through my slab . Are there any 30 amp cooktops?

Will cutler hammer breaker fit GE panel?
Cutler - Hammer manufactures two types of residential circuit breaker for the US. Type CH and type BR. The type BR will fit into most GE panels. It is probably a bad idea to use any other circuit breaker except the type listed on the label of the circuit breaker panel. GE panels require you to use GE circuit breakers. Using any other brand may put you at risk for liability if the installation fails and causes harm or damage.
What is the max load on a 30 amp breaker?
The maximum load on a 30 amp breaker is 30 amps at 40 degrees C. If the ambient temperature is higher that 40 degrees C then the breaker will trip at a lower current. Keep in mind the breaker is a dual function device. On a short circuit the magnetic component will trip the breaker instantaneously. If you are designing a branch circuit for a load that is constantly on, code may require you to "derate" the branch by 20 percent so that the ordinary load is not at the rated load of the overcurrent protection.
What is the Difference between circuit breaker and a relay?
A circuit breaker is designed to break a circuit which is carrying current at the time. Where large currents and/or voltages are present, the opening of the circuit may induce dangerous arcing, so means such as air blast must be used to "blow out" the arc. Air breakers are being phased out and replaced with vacuum or SF6 breakers. An isolator is only designed to isolate a circuit or other component after the current has already ceased, so it doesn't need to have any means to stop the arc. Thus in high voltage/high current installations such as in power stations or grid switching stations, the initial operation to isolate the circuit, whether planned or as a result of a fault, is by the circuit breaker, the isolator is then used to isolate the circuit breaker for maintenance or repair. The difference between a circuit breaker and a contactor is that a circuit breaker can break fault current while a contactor cannot. A contactor is typically implemented in series with a fuse which serves to interrupt fault current. An isolator and a contactor are not synonymous.
Why two trip coil require in breaker?
Transformer is HEART of the substation and Circuit Breaker is the LUNGS of the substation.At faulty condition, large amount of current will flow.so trip function is very important at that timeone coil is faulty means, another one coil will trip the connection to the healthy circuit.
How do you wire 15amp 230v woodworking machine. 10agw or 12agw wire and type of outlet. Into a 15amp or 20amp breaker?
A 20 amp circuit with #12 gauge wire will work in any event but if the nameplate recommends a 15 amp circuit then #14 gauge wire on a 15 amp circuit is sufficient. In either case you will have a double pole breaker and your equipment may not require a neutral. Always run a grounding conductor.
Cause of a circuit breaking tripping?
Tripping is caused by excessive current, which is usually the result of a fault in cable or equipment. The circuit breaker is there for safety and it trips to prevent a possible fire starting.
What size amp circuit breaker would protect a 12kW boiler?
The breaker protects the wiring not the boiler. 12,000 watts at 240 volts will require 50 amps. So, you will need a 60 amp breaker using AWG# 6 wire on a dedicated circuit.
Why two different 30 amp cooktops wont work on a double pole 30 amp breaker using 10 4 wire One 4 wire cooktop only has fan working other 3 wire cooktop does not work at all?
So many variables not presented here. 1) Was it wired by a journeyman electrician? 2) IS the name plate rating as to voltage correct for the circuit supplying it? 3) Is it used or new equipment? Try to give as much info as possible? Once you get them working, one 30 amp 2 pole breaker will not adequately supply two 30 amp cooktops. The breaker will trip. If you intend to operate both at the same time, they need to be on separate 30 amp circuits or one 60 amp circuit which would require larger wire
What the breaker size require for kW?
The use of a breaker in a circuit is to protect the wire size used in the circuit from becoming overloaded. Using the wattage of the load does not help for breaker sizing because the breaker operates on amperage. Amperage can be found from wattage by using the following equation. I = W /E. Amps = Watts / Volts. As you can see the amperage can not be calculated because there is no voltage stated.
Does a residential condo require a main breaker in each unit?
No, a residential condo does not require a main breaker in each unit. Typically, the main breaker is located in the electrical room or utility room of the building, and it controls the power supply to all the units. Each unit may have individual circuit breakers, but a main breaker is not required in each unit.
What are the difference between cooktops and rangetops?
Cooktops and rangetops differ in features and styles. Cooktops are available in gas version or electric version and require specific counter cutout for installation whereas rangetops are only available in gas version and must be installed into both the countertop and cabinet.

What is the problem if the breaker isn't tripped and there is no power to my switch in computer room switch in foyer switch for outside porch and alarm panel is dead?
The most likely problem is that the breaker has tripped. On some breakers there is a indication window that shows a red flag if the breaker needs resetting. On other breakers there is no indication but a slight misalignment of the breaker handle as compared to the other ones. On the distribution panel find the breaker number of the circuit that is off from the panel index. Push the breaker handle to the furthest off position that you can. As the handle is moved to the off position you will feel a bit of resistance. Push past it as that is the breaker resetting. Return the breaker to the on position to see if the circuit has re-energized. The only other reason is that a wire has become disconnected in the circuit. If you have been doing any electrical work on the circuit start looking in that area. To troubleshoot these types of problems it will require the use of a volt meter to check to see if the circuit is "hot" from the breaker out. Then it is just a matter of finding where the voltage stops and locate the problem.

Will multiple tripping of a circuit breaker damage the circuit breaker?
You don't specify whether you mean low-voltage circuit breakers, such as MCBs (miniature circuit breakers) or high-voltage circuit breakers. In either case, repeated tripping under fault conditions causes arcing which damages the main contacts of the circuit breakers. For this reason, high-voltage circuit breakers are taken out of service after a specified number of tripping operations, so that the contacts can be maintained or, if necessary, replaced. MCB contacts are inaccessible, and the MCB may eventually require replacing.
Can you run 14 gauge wire off 12 gauge 20 amp breaker?
You could if it fit properly in the connector, but it would be massive overkill since you only need 12 AWG wire. You also have to make sure the load can physically accommodate that larger size wire. Every so often someone will replace an electric cooktop witha gas one. All of the new gas cooktops require a 110v outlet. The old electric cooktop may have been run with a 50 amp breaker (and probably 6 gauge wire) In order to convert this 220 v circuit to a 110v circuit we change to a 20amp breaker. Depending upon the brand of breaker sometimes the wire will fit into it. If not, we splice on a short piece of 12 gauge wire and then connect to the breaker.
