Functions Of Automatic Transfer Switches

An emergency power backup system has multiple functions and transfer switches adjust the power level as per electric utility at that time. These automatic transfer switches consistently monitor the supply of power to that generating system. In case of any fluctuation, it starts off as an uninterruptible power source that continues until the power restores.

Automatic transfer switches solar serves as an intermediary between power supply and equipment – it acts as an electric relay, which is connected in more than a singular case via a single cord. Since it synchronizes with both secondary and primary sources of power; it is, therefore, known as the safest switch with 80% global demand.

Role of automatic transfer switches in today's homes

In present times, homes require electrical service within the range of 100-150 amperes. In large households, one may need standby generators for matching up to the demands. Those service panels which can include only a specific number of circuit breakers require the presence of such transfer switches to distribute power throughout the house.

Some of the most important functions of these switches are –

1. Protecting the building when the generator is on:

In buildings, if both the generator and electric utility system function, it could lead to a short circuit. These transfer switches negate the need for extension wires and only allow hard-wired appliances to run on the power of a generator.

2. Protecting workers:

In any neighborhood, the electric supply ranges from 4000 volts to 33,000 volts. However, before supplying this electricity, it is marked at 13,000 volts. When electricians work on these lines, voltage comes down to 240 at times, and transfer switches monitor that ensuring safety.
