HVAC Troubleshooting Low Voltage Short

Описание к видео HVAC Troubleshooting Low Voltage Short

Here I am working on a RTU that isn’t cooling. I find no control power and breaker on transformer is tripped. Turns out there is an electric short on the low voltage side. Here I troubleshoot by tracing wires and reading the schematic. I find the short and repair the faulty contactor.
