And if it stops moving, subsidize it. Moreover, they are suitable for both single-phase and three-phase loads. Equipment that is accessible from the back or sides (such as some dead-front switchboards and motor controllers) in which ALL of the replaceable or repairable or adjustable parts can be accessed from locations OTHER than the BACK OR SIDES do not require working space on the BACK or SIDES of the equipment. There's a good chance the actual voltage on your outlet is somewhere in between and it's even possible the voltage is even lower than 220 (say, 218). 220 is what the unqualified use to describe 240 volt circuits. I've not seen an electrical inspector object to those. In North America, this provides the ideal connection for commercial building electric service. Configuration has two live wires for single phase, and three live wires for three-phase. Just remember, there's also a 10% variation for commercial customers (at least in Illinois) in what the utility can supply to you. on 208v Circuit same as 220V for single phase, but more wiring for three-phase. The designation L normally means Line which usually has a hot from the circuit attached, not a neutral. For panels ("operating equipment") rated at 600 V or less, these clearance distances pertain for all electrical equipment. I am considering connecting two of the three phases to the well pump, so it receives 208V where it is expecting 240V. Even more problematic was the pumps manufacturer. For example, a fan running slower moves less air and draws less current. As the diagram below shows, the connection from any live wire to neutral produces an end voltage of 120V. It is even sort of odd that the motor would be listed as rated for 200V. Fatal Shock Hazard Warning: Inspecting electrical components and systems risks death by electrocution as well as serious burns or other injuries to the inspector or to others. Then, step down the voltage to the levels and the number of phases suitable for the end users appliances, using transformers. If the wiring for a 220v outlet is already in place, you should expect to see a flat service fee of around $100 to $150, as this is a relatively quick job.
