Generator Transfer Switch Buying and Wiring. HOW TO CONNECT A GENERATOR TO HOME WIRING. An electrical transfer switch TS is any device designed to connect an electric load to multiple power sources. In home generator applications it is utilized to connect buildings wiring either to an emergency generator or to the service lines. When AC line is normal, a TS allows powering your house from the grid. When the grid fails, TS can switch the home wiring system to a generator while isolating it from mains. This guide will tell you why you need it, how it works, how to choose the right one, and how to wire it a wiring schematic is at the bottom of this page. Its important to know that unless you are off grid, connecting any unauthorized power source directly into any point of electrical wiring without a changeover switch is illegal and dangerous because of so called backfeeding. Backfeeding also called islanding or interconnection by definition is supplying electricity back into electric grid when its down. Here is why it should be absolutely avoided. The voltage fed back into the lines that serve your house poses an electrocution hazard for utility workers and for your neighbors who may not know the voltage is present in the line. Aside from this, your backfeeding home generator most certainly will be overloaded by your neighbors loads in the disconnected local portion island of the grid. It can easily be damaged if power is restored while it is working. REQUIREMENTS AND RATINGS. The standard U. S. Normally, it has red and black hot wires and white grounded neutral. The nominal voltage between each line and neutral is 1. VAC and between two lines is 2. VAC. Note that both lines still belong to a single phase they are obtained by grounding the center tap of the utility transformer. For such a system a generator transfer switch should be double pole double throw DPDT break before make. Double throw means you can place throw it into two positions off position is not counted. Double pole means it transfers both line wires poles. The neutral is normally continuous and does not have to be switched unless your genset is equipped with a GFCI and has its neutral wire bonded to chassis. Break before make means it disconnects load from one source before connecting it to another one.

Power transfer switches for a generator should have three positions LINE, OFF and GEN. When switching between LINE and GEN, they always pass through the OFF position. Such break prevents arcing or short circuits during the transition. If power rating of your genset is not sufficient to feed the entire house, you may install an additional distribution panel a sub panel for the essential lines your want to backup. This sub panel will then be wired to the transfer system. Many commercially available TS come already with a pre wired sub panel. TRANSFER SWITCH TYPES. Generator transfer systems can be manual, automatic, or a combination of both. An automatic changeover is used with standby systems. It includes a control circuit that senses mains voltage.

When utility power is interrupted, the control circuit starts up the genset, disconnects your house from the utility and connects it to the genset. It then continues to monitor mains status. When its restored, it commutates your household wiring from the generator back to the utility. When the generator is disconnected, it goes into a cool down process and then automatically shuts down. Generac and other standby systems usually include a 1. A or 2. 00. A auto TS, or offer it as an option. An auto switch for residential applications may cost 6. Note that you can always set it to a manual mode if desired. A manual transfer switch is normally used with portable gensets. Usually, instead of a true DPDT device, it consists of two double pole breakers with mechanically interlocked handles one is for Genset and the other one is for Line. For the load requirements of up to 3. Create Bdc Program Sap Abap. A, a cheap manual TS with a sub panel may cost under 3. A simple interlock panel with two breakers runs under 1. The wiring diagram below shows an example of connecting a 4 prong portable generator to the house wiring via a DPDT switch for a 3 wire 1. V service. The dotted lines symbolically show the metal cases. In this diagram neutral is not grounded inside the genset. For simplicity an inlet is not shown. Here is a little known detail. Many portable models sold in US nowadays have a GFCI GFP and their neutral is bonded to the metal frame. Driver Converter Stick Ps2 Bios'>Driver Converter Stick Ps2 Bios. This causes a problem when you are trying to use them with a TS when neutral is grounded in two places its current will split, and the GFCI on the generator trips. How To Use This Manual.

Install a Transfer Switch and Beat the Next Blackout A transfer switch is a convenient way to pick and choose which appliances and items to keep running via generator. As the result, no outlets will function. There are several possible solutions to this problem. The safest one is to install a so called neutral switching device 3 pole isolation switch. It will control neutral along with two power lines. Another solution is to lift inside the transfer equipment the ground wire from the genset just isolate its loose end. Your genset will still be grounded via its neutral bus. Finally, one may remove the neutral bond inside the genset, which disables GFCI. This option is not safe though if you will ever use such a device in the field without a TS for example on a job site, you will not be protected from electric shock. Such modification may also void the manufacturers warranty. In any case, all installations should be done by a licensed electrician. You can find one andor get an estimate by using the search tool above. And of course, for everyones SAFETY, make sure the main circuit breaker is turned OFF BEFORE any wiring work started.
