Upgrading your service will not keep individual circuits from tripping.

An overloaded circuit on a 400-amp service will still trip.

Large individual loads require their own circuit.

Large circuits with multiple outlets and numerous simultaneous loads should be broken up into multiple circuits as suit the loads.

The only time it is necessary to increase a service from 100 amps to 200 amps is when the combined loads dictate the necessity.

A 100-amp service is usually adequate for a three or four bedroom home with electric hot water, electric stove and electric dryer.

A 200-amp service would be necessary if total electric heat is contemplated. <><><>

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.

If you do this work yourself, always turn off the power

at the breaker box/fuse panel BEFORE you attempt to do any work AND

always use an electrician's test meter having metal-tipped probes

(not a simple proximity voltage indicator)

to insure the circuit is, in fact, de-energized.

When do you know if you need an electrical service upgrade?

1) If you are tripping the main breaker and you do not have an electrical fault in the home. 2) If you are installing additional circuits or appliances and you expect to exceed 80% of the load capacity of the existing service panel.

You have problem of simultaneous tripping with other small power circuits but not instant?

Answer for countries in Europe and other world areas running a 50 Hz power supply service. Tripping of what - RCD would probably point towards an earth/neutral fault Tripping of MCB would point to a small overload or a circuit with a thermostatically controlled device such as a fridge.

How do you wire a 220V 50Hz induction cooktop max 4.6kW in a 110V 60Hz service?

There comes a time when you simply have to upgrade your electrical service. A 60hz service was never designed to handle all the power requirements of a modern home. When the 60hz service came in, it was designed to handle a few lights and a few receptacles. I'd be surprised if you had more than 4 circuits on your board and I'm betting that you are blowing fuses or tripping circuit breakers constantly. Bite the bullet, upgrade your service.

How many circuits can you have with 100A service?

As many as you want without exceeding the 100amps. You could have 100 circuits if all you have is a single 100watt light on each circuit.

Can you use a GFCI on an unswitched circuit line red that uses the same neutral white for a switched circuit coming from the other phase line black in a 240v breaker panel?

Yes. You are allowed to use a neutral for one circuit from each phase of your service. For example, in a residential service, you can use the same neutral for circuits 1 and 3. In a commercial (3 phase) service, you can use a neutral for circuits 1, 3, and 5. You will experience problems if you use a neutral for two 'black' circuits or two 'red' circuits, if the circuits originate from the same phase bus bar. Also, AFCI's are sensitive to sharing neutrals, but GFCI's are not.

How does electricity get distributed in the household?

Electricity get distributed in the household through electrical circuits. The circuits distribute voltage to receptacles, light and hard wired appliances. These circuits are fed from breakers that are in the distribution panel. The distribution panel is where the utility company's service supply terminates. The distribution panel is the central location where the household circuits originate.

How do you wire new garage?

You need to determine what your power requirements are for the garage. This would include general purpose outlets, specific high demand power equipment like air compressors, welders, lifts and so forth, garage door openers and lighting. This will determine what circuits you need and the amperage of each. You will also need to determine the layout of equipment so that the feeds are in the proper location. You then need to determine if you have enough circuits in an existing panel or need to run a subpanel. You also need to know if the amps supplied by the power company are sufficient or if you will have to "heavy up" your service. Do the preliminary design work and then get 3 bids from electrical contractors that you know or are recommended to you by those you trust.

How many 20 amp circuits can you run on a 50 amp service?

In the United States, there isn't a hard limit on how many 20 amp circuits that can be run on a 50 amp supply. This is because in most cases, especially in homes, we don't load most circuits with more than an amp or 2, even when they are protected by a 20 amp breaker. From a practical perspective you probably have a limited number of slots for breakers in your service or supply panel.
