In case of emergency breakdown when utility power is not available from the power house, we may use automatic inverter / UPS and batteries to connect the power without interruption.
We will show two basic UPS / Inverter with batteries connection the home distribution board.
Note: To be in safe mode, use 6 AWG (7/064″ or 16mm2) cable and wire size to connect the UPS to the main panel board. Minnesota criminal law handbook.
Automatic UPS / Inverter Wiring with two Wires.
No rocket science here. Just connect the outgoing Neutral and Live wires to the UPS. Now connect the two outgoing Neutral and Phase wires from UPS / Inverter (As output) to the appliances as shown in fig 1.
UPS / Inverter Wiring with Single Additional Live Wire
As a basic, we know that each load points should be connected through Live (Phase) and Neutral wire to operate normally. In case below, we have already connected the Phase & Neutral (from Power house to the utility pole & Distribution board then) to each electrical appliance i.e. Fans, Light points etc.That’s what we do in our distribution board for home wiring.
The individual pages in Powerpoint displays are called as slides. Any slide can be easily deleted or inserted, in line with the requirement. The purchase of the slides could be changed anytime. This content of the slides might be arranged in any manner. Download ppt theme. Slides may consist of text, images, maps etc.
Now, according to the below UPS connection diagram, connect an extra wire (Phase) to those appliances where we have already connected Phase and Neutral wires from (Power house & DB) (i.e., two wire as phase (Live) as shown in the below fig). And no need to connect extra Neutral wire from UPS as it is already installed & connected before. In simple words, You only need a live wire to connect to the appliances as shown in fig 2. Now the quieten arise here “Why extra Phase wire and not a Neutral ? … Yes. Read the following working and operation of the circuit to get the idea.

Working and Operation of UPS Connection
(1) When utility power is not available from power house
Ups Circuit Diagram Pdf
In this case, electric supply will continue through Phase wire (Output of UPS) which is connected to the batteries and UPS and then to electrical appliances (Note that Neutral is already connected). So the first one phase wire which has already connected before UPS installation (i.e. Live Wire from Main board to UPS) would be inactive because power supply is not available from power house. In this case, connected electrical appliances through the live wire from UPS / Inverter consume the stored electrical energy in the batteries without interruption.

(2) When power supply restores from power grid
Then power supply will continue through the Phase wire (Note that Neutral is already connected) which is connected to the UPS from main board (it will charge your battery as well) and then from UPS to connected electrical appliances. So the second one (phase or live wire) which is connected after UPS installation (i.e. One Live Wire from UPS) would be inactive because power supply is not available from UPS and batteries (Because it is Automatic UPS System).

Wiring Color Code:
We have used Red for Live or Phase , Black for Neutral and Green for Earth Wire in single phase. You may use the specific area codes i.e. IEC – International Electrotechnical Commission (UK, EU etc) or NEC (National Electrical Code [US & Canada] where;
NEC:
Single Phase 120V AC:
Black = Phase or Line, White = Neutral and Green/Yellow= Earth Conductor
IEC:
Single Phase 230V AC:
Brown = Phase or Line, Blue = Neutral and Green= Earth Conductor.

What is UPS and Its application?
An inverter or UPS is a device that typically provide power backup in emergency to a device or load, when normal electricity power source is down. UPS is an abbreviation of Uninterruptible Power Supply / Source. UPS Schematic circuit diagram DC-AC is below (Figure UPS) showed.
It differs from from generator or other power backup systems, As it provides almost immediate protection and provide quick backup energy available in the connected batteries, flywheels, super capacitors. The backup time of the batteries of most UPS or inverters is relatively short (in minutes), but enough to start a proper backup power source or to turn-off the protected device / equipment for safety. An inverter is to regularly back up equipment, like computers, server farms, telecom installations or other electrical transmission where incredible power outage could result injury, death, actual business interruption or loss of information.
UPS varies from unit size for a single PC without monitor to ensure (VA 200 rating) to larger units, which provides the whole data-centers or buildings with electricity. The biggest UPS in the world in the world that has rated power backup of 46 megawatts electrical storage (BESS) is Alaska in Fairbanks, , provides the whole city & neighboring communities during a power outage.
This under given inverter allows the use of 230V electricity from a car battery or a solar battery rated with 12volts. Ideal output of the ups should be RMS 230 volts with sign wave and frequency of 50Hz. The advantage of sinusoidal voltages is the soft and slow escalation of volts which reduces adverse effects on motors, interference on radio equipment and current surge to the capacitors. Under given inverter provides backup up to 3000 VA, from 12 volts, outputs modified sinus-wave.
UPS power mainly depends on 2 factors, i) Transformer wattage ii)Power Driver (transistor array, or Fets), backup timing of any inverter depends on battery capacity and output power usage.
