what is the difference between national grid and con edison?

Con Edison provides service throughout most of the city, except for some parts of Brooklyn, which are covered by National Grid. (National Grid is a regional company that services gas in New York, Massachusetts and Rhode Island).

One of the key differences between an AC and DC generator is that in the former, the electrical current reverses direction occasionally, while in the latter, electric current flows progressively in one direction.

DC circuit breaker, like their name suggests, is used for the protection of electrical devices that operate with direct current. The main difference between direct current and alternating current is that in DC the voltage output is constant, while in AC it cycles several times per second.

Alternating current is cheaper to generate and has fewer energy losses than direct current when transmitting electricity over long distances. Although for very long distances (more than 1000 km), direct current can often be better.

The main technical difference between inverter generators and conventional generators is what kind of electricity is produced. Conventional generators only produce AC electricity while an inverter generator produces electricity in 3 phases (high frequency AC to DC back to a stable AC current).

The difference between AC and DC lies in the direction in which the electrons flow. In DC, the electrons flow steadily in a single direction, or "forward." In AC, electrons keep switching directions, sometimes going "forward" and then going "backward."

The key difference is how the outlet cover attaches to the receptacle. The standard style uses a screw (seen between the two outlets) while the Decora simply clips into the cover. If you have a GFCI power outlet, then for the purpose of baby-proofing; consider it a Decora outlet.

The complexity of DC fuses sometimes results in a higher cost than AC fuses that may contain only a single element. There are fuses with equal AC and DC voltage ratings, but the DC interrupt rating is significantly less than the AC interrupt rating.

The major difference between the two is that continuous generator sets are designed to operate continually with a consistent load while prime generators are designed to operate for long durations at variable load.

An off-grid solar energy system is not connected to the utility grid, whereas an on-grid (aka grid-tied) solar energy system is connected to the utility grid.

Direct current (DC) electricity is what solar panels produce and what batteries hold in storage, while alternating current (AC) electricity is the type used on the grid and in most household devices. A device called an inverter is required to convert the DC electricity from solar panels into appliance-friendly AC.

Hence the main difference between the two is - Fuse switch disconnector can make, carry, and break the circuit along with providing overcurrent protection to the installation; while fuse can only provide overcurrent protection.

The basic difference between the two can be understood from their names, DC generator gives Direct Current(DC) and Synchronous Generator gives Alternating Current(AC).

On-grid means your solar system is tied to your local utility's GRID. ... Being grid-tied is beneficial because you don't have to buy an expensive battery back-up system to store any excess energy. Being off-grid means you are not connected in any way to your grid's power system or utility company.

Electricity is less expensive than gasoline and EVs are more efficient than gasoline vehicles. Electricity prices are also generally much more stable than gasoline prices. On a national average, it costs less than half as much to travel the same distance in an EV than a conventional vehicle.

The simple answer to this is that on-grid (a.k.a. grid-tied) solar systems are connected to the main utility power lines called the grid, while off-grid systems are not. An off-grid system may require batteries and, sometimes, a back-up generator; while an on-grid system doesn't.
