Hey Guys,
As said in the title, we recently purchased a new control panel that controls a hydraulic system at our facility (pump, 3Ph motor, solenoids and everything was included in the package from the panel builder).
We requested a 208VAC panel since we already had a distribution panel nearby where we could add the extra breaker for the new panel and running the electrical supply would be simple. The quote the panel builder supplied has 208VAC listed in the panel specs as its input Voltage.
Unfortunately we opened the crate earlier and we noticed that the panel was designed for 480VAC. We called the manufacturer and they basically told us not to worry that the panel would still work. The answer we received from the technical assistance desk was very quick so I have my doubts about his answer.
I just wanted to run this by you guys. I'm new to this job and I don't want to challenge the panel builder/designer without checking a few things.
- By supplying a lower voltage to the panel won't we need more current (Almost Double) to meet load? Therefore wouldn't this mean the breakers would be undersized?
- Also, since more current would be needed. Shouldn't the wires be a larger gauge? It looks like thje wire Gauge is 14AWG so I think we should be fine since it's a pretty small pump.
- The 24VDC power supply is rated for a input range of 400-500VAC. If we're only supplying 208VAC the power supply won't be functioning correctly.
- Also, the panel they supplied is supposed to be UL Certified. I would assume by changing the input power, the certification would not apply.
For us to supply 480VAC to this panel would take a lot more work, and if this is the case were probably going to ask them to supply what we ordered or ask them to pay for the extra electrical labour.
Any advice would be greatly appreciated.
