Hi guys i am residential guy and starting commercial job need your help in understanding these voltage systems 347v 575v 600v.

347v 3 phase wiring diagram. A three phase motor must be wired based on the diagram on the faceplate. 120v 3 phase line to neutral commercial industrial and some large residential loads. The sdsa device is designed to provide surge suppression for three phase services.

The first step is to figure out the voltage of your phases. This instruction sheet provides installation instructions for sdsa3650 sdsa4040 and sdsa2040 surge protective devices. In the united states for low voltage motors below 600v you can expect either 230v or 460v.

208v 3 phase line to line commercial industrial and some large residential loads. That being said there is a wide range of different motors and what you have on hand can be completely different. Three phase 3 line connection consist of three phase conductors and is employed only where there is no requirement for connecting phase to neutral loads.

240v split phase line to line. 600v 3 phase line to line high power industrial and commercial loads. 347v 3 phase line neutral high power industrial and commercial loads.

Three phase systems can be three phase three wire or three phase four wire systems.
