Can I hang a picture in front of an electrical panel in a commercial office space? When a motor is rated at 208/230 volts this means the motor will operate at the 208 volt rating, not 10% under the 208 volt rating. Three-phase loads connect to phases A, B, and C. In addition, in the case of a 120V line-to-neutral supply, the voltage between the wild leg and neutral is 208V as the diagram below shows. These cookies will be stored in your browser only with your consent. Most devices designed for 220 will run on 208 and in shops all over the place this is commonly done. But if you want to accommodate heavy equipment in a commercial setting, use three-phase power, especially if you have various types of devices that require different voltages. Most devices designed for 220 will run on 208 and in shops all over the place this is commonly done. 208 is from a 3 phase system and 240 can be from a single phase or a 3 phase system. With electrical loads, the voltage will drop, hence the common reference to voltages below 120 and 240, such as 110, 115, 220, and 230. This section outlines the differences between 208V, 220V, and 240V, which are all standard voltages for power supply. How does the efficiency curve of a well pump shift with speed? You can also infer the electrical panel height from U.S. NEC 110.26 Spaces About Electrical Equipment, NEC 110.26 (A) Working Space, (3) Height of Working Space: The work space shall be clear and extend from the grade, floor, or platform to a height of 2.0 m (61/2 ft) or the height of the equipment, whichever is greater. 240V accommodates applications with lower power requirements than 208V.

It would only interfere with the work space as much as a kick board would. My Bridgeport mill's motor is rated 230/460 3 phase. I've run it for over 10 years now on 208. No problems yet. This configuration is suitable for a range of nominal service voltages such as 240V, 400V, 480V, and even higher. If it says 208-240V you could have it wired to the service panel if the panel rating is big enough to handle it. "Electrical Systems," A Training Manual for Home Inspectors, Alfred L. Alk, American Society of Home Inspectors (ASHI), 1987, available from ASHI. So, your machine will work, but will take longer to come up to temperature.

The important dfference, othere than maybe having too high or low a voltage, is that one of the input leads is either ground referenced or both are hot. This high-leg or wild-leg configuration is common in older manufacturing facilities. Current in a 220V single phase circuit requires a grounded neutral. I have a 120V lighting panel that is 4 1/2 " deep and below is a pull-box (Only) however it is 12" deep. The cookies is used to store the user consent for the cookies in the category "Necessary".

I should just use the code for clearance around the panel. I've not seen an electrical inspector object to those. City code inspectors approve permits when lot owners upgrade there lots by adding new electrical circuits for outdoor kitchens, lighting etc, and have never objected to our RV or fences being within inches of the panels. But if it is running at full load, you might find it overheating, tripping overloads, or just generally failing early. The power and efficiency of your appliances will drop. The motor should run fine if the service line voltage is between 209 and 253. for short periods, 240VAC will not burn out a 220VAC motor. You are using an out of date browser. You find three-phase in commercial settings. For example, a fan running slower moves less air and draws less current. (150 mm). 240 volts can be obtained from either a 120/240 residential system or a 240 volt 3-phase delta system. Circuit has more wiring because of three-phase. @Mark, That power loss makes 240V more costly because the voltage drop will harm your appliances. How about saving the world?

This sounds like an inconvenience, but it can cause lasting damage. 240V is the line to ground of a 415/240Y system. You dont have to deal with the voltage drops that make single-phase systems so annoying. Moreover, two live wires of 120V each, convey this power, with most appliances making use of either of the live/hot wires. So if your supply is 208, your current will increase by a ratio of 240/208, or about 15%. However, if the operating conditions are a heavy load at or near nameplate full load rating, operation at 3-phase 208 volts could result in higher operating amperes, resulting in higher operating temperature. Can I use a 230-volt motor on a 208-volt motor, for example? However, because the motor is doing less work, the volume of current it uses wont increase as dramatically as you might expect. Technically speaking, you dont have to choose between these two options. Can a 240v single phase motor run on 208v? This question was posted originally at ELECTRIC PANEL INSPECTION.
