50Kva Single Phase Pad Mounted Transformers Power Distribution Loop
Feed Additive Polarity 240V To 480V UL Listed
Single-phase pad-mounted transformers are compact, self-contained
electrical devices primarily used in residential and light
commercial settings. Their primary application is to step down the
high-voltage electricity supplied by the utility company to a lower
voltage suitable for home or small business use.
