Surge protector error code

An open Neutral will cause voltage issues and possibly burn up appliances. An open ground could lead to a "hot skin" situation.

Consider yourself lucky, an open ground with 50a service can cause a voltage imbalance and fry appliances. That device saved you some $$.

If you plugged in hot the EMS May have seen power before the ground. Remember P means previous if you now have good power the ground is good.

While possible, this should be unlikely due to the design of the plugs and sockets. The ground prong is longer than the hots (and neutral) so it makes contact first--at least that's the theory.

The EMS is actually looking for a voltage difference between the ground and neutral, and complains if it's anything much greater than zero. The actual problem could be a poor neutral connection somewhere, or a poor bonding between ground and neutral at the main panel, in addition to a poor ground connection. It cannot detect whether the ground is a good earth ground or not, since it has no reference to earth potential.

"p" means previous and then use the codes below

E-0 Normal Condition
E-1 Reverse Polarity Condition (hot and neutral wires
Reversed)
E-2 Open Ground (means no ground wire connection)
E-3 Line 1 Voltage High (Line 1 voltage above 132 volts)
E-4 Line 1 Voltage Low (Line 1 voltage below 104 volts)
E-5 Line 2 Voltage High (Line 2 voltage above 132 volts)
E-6 Line 2 Voltage Low (Line 2 voltage below 104 volts)
E-7 Line Frequency High (Line frequency above 69 cycles
per second)
E-8 Line Frequency Low (Line frequency below 51 cycles

E-10 Replace surge protector mode

Thanks for the great response, I need to recheck the ground thru the sub panel.

thanks, good to know
