How Automatic Transfer Switches Are Used? | Others/Assorted

by Rudy Silva

An automatic transfer switch is leading whenever there is a penury for transfer a power provision provenience. The transfer of a power authority can be from the ranking beginning to minor, tertiary. Transfer switches are very vulgar in power issuance systems. They are also tip in places where there are generators and backup power facilities. Most hospitals and other depreciatory duty services have backup generators.

Many electrical and electronic engineers, as well as electricians like to industry on auto transfer switches more than they do on vade-mecum switches. The auto switches have the step to transfer loads of ardour when there are power interruptions, or when there is a want to transfer the power beginning from one electrical system to another.

If there is a voltage converting in a power come up with, a transfer switch can bring to a halt internal perimeter indemnity to your appliances or computer. An Automatic transfer switch can transfer power from the basic commencement to a backup power provenance such as a generator. As extensive as it does not show resolve in voltage and frequency, the pipeline power endow does not take on oneself back being the predominating power originator.

Installing a house generator. Can anyone tell me a little about the automatic transfer switch. install?

I have everything connected except for the transfer switch to the enterprise. I just want to make sure I am doing this correctly.

What benevolent of automatic transfer switch do you have? Does it have a built-in loadcenter (panel)? Is it a weatherproof one with a built-in main breaker?

Depending on the make of generator that you have, this will probably not be a DIY project. Generac generators comes with very good DIY installation instructions for their 7kW - 16kW generators. They fancy to have their larger generators installed by a professional.

If your transfer switch has a built-in loadcenter (panel), I recommend installing it good next to your existing breaker box. You need to install a conduit between your transfer switch and generator. In this conduit, you will run your 2 - hots, 1-non-belligerent and 1-ground for the power from the generator. Additionally, depending on the requirements, you need to install a minimum of 2 conductors that nuance utility power and allow the generator to start.

The conduit size depends on the size of wire and enumerate of conductors in the conduit. The wire size is determined from the generator size. All of these specifications should be in your installation instructions.

You also prerequisite to install a conduit between your transfer switch and existing breaker box. In this conduit, you need the utility power to feed the transfer switch and the circuits that you wish your generator to control during an outage. These circuits are already in your existing breaker box, you just need to transfer them into your transfer switch.

Don't omit to ground your generator. The instructions will have the specifications for grounding. Typically, you need to drive an 8' x 5/8" compass basis rod next to the generator and connect a #6 bare copper wire between the ground rod and a lug provided on the generator's casing.

As I mentioned earlier, this is not really a DIY project. If you are unsure of any of the steps involved, I highly recommend hiring a licensed electrician. If you are prospering to do this yourself, definately get an inspection when you are done, just to be sure.

Be sure to check with your local building codes to see if they have any additional requirements. I also approve getting the 2005 edition of the NEC and read Article 445.

Does addition of automatic transfer switch increase electric consumption?

Jul 25, 2007 by Gut W | Posted in Engineering

We are a paltry business with a pre-existing standby power and manual transfer switches. Recently we have changed to automatic transfer switch system. The following month, our moving bill went through the roof. We didn't add any loads, in fact that was one of our slow months. But the consumption was >1,000 kilowatts more than our accustomed for the past several years. Does this have anything to do with the ATS? Anybody has any idea?
I also doubt it's the switch but it's the only change we did. Yes, it's >1,000kwh/month than our same. We had one of the meters changed, but the utility company said the previous one was fine. We're going to assay the load on all the lines.
Sorry if I am confusing everyone.. our usual consumption is 4000-5000kwh/month. Last month it was almost 6000 kwh from the past 4700 kwh.

To place an automatic transfer switch it may have been necessary to remove the electric meter. Check the serial number of the meter against your bill. Ask the electric firm to check the meter.

Are there other tenants in your building? If so, get an electrician to make sure someone else didn't get connected to your meter.

Estimate sure that some equipment that normally cycles on and off is not going bad and running all the time. Check refrigeration, air conditioning and compressed air compressors. Substantiate fans.

Make sure hot water is not leaking or going through the safety valve down the drain. Restrain for compressed air leaks. Check for a broken air conditioning duct leaking cold air into a wall, untrue ceiling or attic.

How dose a automatic transfer switch work?

It senses the sang-froid of the normal source of power, and switches the load to the standby source if the normal source is not within agreeable tolerance. If the standby source is a generator, it starts it. Once the normal source is restored and stable for a immobile time, it transfers the load back.
