Hi Rob,
I forgot to make a note of what the voltage was during our test today. I imagine it was like the other day, a drop from 122 to maybe 112 or so. The EMS shuts it down at 104 or lower.
The manager is calling the electrician on Tuesday, don’t know when they will respond. Soon I hope. She also is buying me a long 50 amp extension to plug into the site behind us. I carry a 30 amp extension, but it’s currently loaned to my neighbor, and I’m not sure it would reach anyway. I’m gonna measure the distance as soon as the guest behind me vacates. They’re packing up now.Steve & Sue (pups:Sky & Sierra) Gardnerville, Nv

Why didn't the EMS shut down? We were at a 30 amp site and it was Green Acres! My EMS shut down before the breaker on pedistal tripped....

Hi Jim,
The EMS shuts down at low voltage of 104 or below, or high voltage, I think 132 or above (somewhere in that range). As far as amps I’m not sure if it shuts down at high amps, but my total amps were added up from both lines anyway. My trailer is a 50 amp trailer, and my EMS is a 50 amp EMS. It should allow 50 amps on each leg, and there are two legs in the EMS and the trailer. So theoretically it can handle 100 amps. The trailer individual circuit breaker would likely trip before reaching that.Steve & Sue (pups:Sky & Sierra) Gardnerville, Nv

I didn't see overload/overcurrent protection listed in the Features.
Features:
High/Low Voltage Protection: Whenever source power falls below 104 volts, or rises above 132 volts the EMS automatically shuts down power to the RV.
Once the AC power source raises above 104 volts or below the 132 volt level the time delay indicator flashes for the preset time and then automatically restores power to the RV.
Time Delay for Air Conditioner Compressor: Whenever power is interrupted by the source or the EMS due to a fault condition, the built in time delay is activated.
There are two settings on the EMS. One is 136 seconds, and the other is 15 seconds.
Consult your air conditioner manual to see if it has a time delay built into it. If so use the 15 second delay if not use the 136 second delay.
Five mode surge protection: This feature provides full surge protection L-N, L-N, L-G, L-G, L-L, and N-G. Total joule rating is 3640, response time of <1 nano second.
Surge Indicator: In the unlikely event a power surge damages the surge protector circuit within the EMS (L-N, or L-G) the digital display error code will read E-10.
This is your indication that it needs to be replaced.
Reverse Polarity Protection: If source power has reverse polarity the EMS will not allow power to the RV and the error code will read E1.
Open Neutral Protection: If the source has an open neutral the display will not light, and the EMS will not allow power to the RV.
Open Ground Protection: If source power has an open ground the EMS will not allow power to the RV and the error code will read E2.
AC Frequency Protection: If the source power frequency deviates + or - 9 hertz from 60 cycles per second the EMS will shut power down and the error code will read E7 or E8.
Accidental 220V Protection: If 220 volts is detected when plugging into source power the EMS will not allow power to the RV and the EMS will not be hurt. If this
condition occurs while power is applied to the RV, the EMS shuts off power instantly. In either case the display will read the voltage and E3 or E5 will be displayed depending on the error.- Gene

Hi Steve,
It will not hit 100 amps it is 50 amps max between both legs. I would need to check the trailer but unless I am mistaken each leg is only rated for 25 Amps, maybe 30 Amps max. If this is not correct please someone correct me.
Read through the post and it is a very good thing that they are getting a licensed electrician out because something is very wrong here and potentially extremely dangerous. If the CB shuts off power to the trailer but does not trip over 30 amps then it is defective even if it is the second one. If it was wired incorrectly then it wouldn't shut off power to the trailer.

Can you do a quick test? Where the wire comes out of the breaker at the pedestal, put the clamp meter there and note the amps (with all your loads). Then put the clamp on the neutral and measure the amps and report back please.
