After this post you will complete learn "how to make UPS inverter at home diagram". In this blog i also share how to connect the UPS to battery or batteries. How to wire the ups for home wiring. Or how a UPS inverter wiring. In this post i will teach you how to make ups inverter at home. There are different types of UPS / inverter are available in market. And you can buy it from any offline or online markets according you load.


How to make a UPS/Inverter at home


In the market the circuit is available which also use for making a UPS in home. In this post i am sharing a complete UPS internal wiring diagram. In which the controlling kit, UPS module, UPS transformer, outlet, fuse, on/off switch etc are shown.

In the below "UPS/inverter how to make diagram" all the connection shown step by step

how to make ups inverter at home diagram

In the above UPS/Inverter transformer, the transformer bobbin size is 2'' x 3''. The 19 SWG and 11 SWG used in coil.  The Winding turns and winding formula shown in above diagram. I hope after this diagram now you will be complete understood the complete UPS (uninterruptible power supply) wiring. This below articles and diagrams also help you..  Note that this is a Desi UPS wiring diagram.

This post is about the dol starter diagram. As you know that dol starter is a starter which contain a magnetic contactor, overload protection relay and NC/NO push button switches. I also share the dol starter wiring diagram. In which I shown the MCCB circuit breaker (molded case circuit breaker) magnetic contactor and thermal overload relay and complete controlling and power wiring. In the today dol starter diagram. I will only shown the symbol type diagram. This diagram contain the complete wiring of a direct online starter.


DOL (Direct Online Starter) Wiring Diagram




In the above dol starter diagram. The R,Y,B is the three phase 380 volts supply. The coil of the contactor is 380 VAC. And the normally open and normally close push button shown. the contactor connection with thermal overload relay and the motor connection with overload relay is shown. Also the earth connection is provided to the motor.

3 phase current transformer wiring diagram for 3 phase load (ampere) testing. As you know that we use the current transformer to measure the current. For testing the current (ampere) running to load we use two types of amp meter. In which one series type which is wired in series between load and supply. And 2nd is a current transformer type which is wired with a current transformer to measure the current. We can wire a current transformer for single phase and also for 3 phase. The current transformer is always used for line ampere testing. For 3 phase system ampere testing every Line have their own current transformer. And these current transformers further connected with 3 ampere meter or one ampere meter and ampere testing selector switch.

For better understanding also read below

How to 3 phase current transformer wiring diagram with ampere meter


Note that if your ampere meter is 100/5A then used only 100/5A ratio current transformer. In the below 3 phase current transformer wiring diagram with amp meter. 3 CT coil, and Amp testing meters shown. The current transformer wiring for each meter.


3 phase current transformer wiring diagram


You can wired the current transformer for three phase system as shown in above diagram. However if you want testing 3 phase ampere with only one ampere meter. Then use ampere selector switch with current transformer. For that you need to wire the all 3 current transformer with amp selector switch. And from the selector switch the two wire supply will goes to ampere meter. From the selector switch you can test at each line(phase) ampere.

This post is about the 4 way switch wiring diagram. A 4 way switch is a type of switch which is used for switch off/on a light or other electric devices from multiple places. Today in this below 4 way switch wiring diagram. A light is controlled from 3 places. This light bulb can be switch on/off from each switch. For example if a person switch on the light bulb from the first switch then he/she can switch off it from 2nd or 3rd switch.



How To wire a 4 way switch diagram


In the below 4 way switch diagram, a light bulb is control from 3 switches. The first and 3rd switches are 3 way switch, (note that it's also known with name of 2 way switch). And 2nd switch is a 4 way switch.
The neutral wire is shown black color and line wire with red color. The green color is used for earth or ground wire.

Forward reverse starter with timer 3 phase motor wiring diagram. In my last posts I share the wiring diagram of forward reverse three phase motor starter and also the 8 pin timer wiring diagram. This post is about the main and control wiring of forward reverse starter with timer. In the below diagram the main wiring for 3 phase motor is also shown and control wiring is also shown. In the diagram two magnetic contactor shown which coil operated on 220 volts. You must need the neutral wire. However if your magnetic contactor coil is operated on 380 volts then you do not need neutral wire. In the forward reverse starter with timer diagram. The thermal overload relay shown, a normally close push button and two normally open push button shown.

Forward Reverse Starter with Timer 3 Phase Motor Wiring Diagram



In the below forward reverse with timer starter diagram. The timer is used for automatic off (or automatic switch off the motor when the motor complete his running time.


forward reverse starter with timer 3 phase motor wiring diagram

All the wiring connection of forward reverse starter with timer shown. The timer is used only for one contactor. And timer will only switch off one contactor with its complete his time. The control wiring of starter is shown clear to understand. If you want need more help then also read the below post.
