Is it difficult to change an ERV wired for 460/60/3 to 208/60/3?
When you have an ERV wired for the wrong voltage, it can be corrected. However, voltage change outs on ERVs are time consuming and expensive. Several components must be changed out including: Fan motors, if the motors are not multi-voltage. Fan drives, if the motor frame size changes. Motor starters, contactors and overloads will need to be changed out in most cases. Disconnect size may change. Wiring will need to be rerun to handle higher amp draws at the lower voltage. Please double check voltage requirements before releasing orders.
