Info on Hzs

[BigOL3]

I have the MEP 003A and need info on what is the acceptable level of hertz, without causing a problem with appliances. I know 60hz is perfect, but generator fluctuates a little as appliance come on or off. If set at 60 but 4ton and 2ton AC kicks on, it will drop to 58+. If on one is on, it will be 59+. If set to 60 after BOTH AC is on, but then AC cuts off, it will go to nearly 62. Can anyone advise the acceptable Hz tolerance?

Typically 5% is close enough unless your equipment has sensitive electronics. 57-63hz shouldn't cause any issues.

Just for peace of mind sake, Generac for many years made generators that ran at 58hz in order to be just that little bit quieter when running.
I have yet to hear of any issues because of it, other than maybe some clocks ran a little slow.

Good info, thank you!

The grid doesn't give you 60hz consistently, it too varies. Many modern appliances use DC controls anyways that accept down to 50hz. Your items should be just fine.
