OPERATING INSTRUCTIONS

MODEL 44750

WARNING

1.  If the unit with contacts closed fails to trip when the 

TEST

 button 

is pressed (Green light still appears), the device is NOT operating 

properly and should be return to the point of purchase for replacement  

(SEE WARRANTY INFORMATION)

2.  If the product tests properly without a load applied, 

but trips each time the RV load is applied, a current 

leakage exists and should be repaired or replaced as 

soon as possible 

(SEE WARRANTY INFORMATION) 

 

DO NOT BYPASS THE SURGE GUARD IF THIS CONDITION 

OCCURS.  A REAL SHOCK HAZARD MAY EXIST.

IMPORTANT NOTE

The Surge Guard* Model 44750 will provide protection even if there is 

a break in the ground wire in the supply power circuit or the internal 

circuit in the RV.

CAUTION

1.  Do not connect any electrical cord longer than 250 feet to the 

Surge Guard* device to avoid the possibility of nuisance tripping.

2.  This device is to be used on electrical distribution systems 

120V/30A (RV30) 60Hz only.

3.  Ground fault circuit interrupters do not protect against electrical 

shock resulting from contact with both line and neutral wires of the 

electrical circuit.

4.  The Surge Guard* Model 44750 is designed as a protective 

device, do not use as an "on and off" switch.

TROUBLESHOOTING

MODEL 44750

RV's, new and old, can have loose, faulty or even incorrect wiring 

which could be potentially dangerous.  In the event there is a leakage 

of current caused by one or more of the above conditions, the Surge 

Guard* Model 44750 will cut the flow of electricity.  Should this happen, 

follow the procedures below to isolate the cause; however, Southwire

TM

 

recommends that all electrical repairs be done by a certified electrician.   

1.  Unplug the RV from the Surge Guard* device and push the 

RESET

 button.  If the unit trips immediately after, the problem is 

in the Surge Guard* unit and it should be returned for repair or 

replacement. 

(SEE WARRANTY INFORMATION).

  However, if the 

Surge Guard* unit holds the set, continue to 

Step 2

.

2.  Turn off all the RV circuit breakers and plug the RV power cord into 

the Surge Guard* device.  If the unit trips, the problem is in the 

cord and/or the connection supplying the RV.  However, if the unit 

does not trip, continue to 

Step 3

.

3.  Turn on each circuit breaker one at a time until the Surge Guard* 

device trips. You have now isolated a circuit with leakage.

4.  Unplug all appliances connected to the bad circuit and reset the 

circuit breaker and the Surge Guard* device.  If the unit trips, then 

the problem is in the RV wiring.  Should the Surge Guard* device 

not trip, see 

Step 5

.

5.  Plug in each appliance until the Surge Guard* device trips.  The 

appliance that causes the trip has a current leakage and should 

be repaired or replaced.

WARNING

Some RV power pedestal receptacles, regardless of amperage, can 

cause discoloration, charring, and even melting of the male plug 

connected to it.  This condition is created by worn or loose receptacle 

connections resulting in unsatisfactory tension or gripping force applied 

to the current-carrying blades on the male plug.
To reduce the risk of plug damage, keep the male plug blades on 

the Surge Guard* device and RV power cord clean and tarnish-free.  

Visually inspect in and around the pedestal receptacle for evidence of 

charring prior to making connection.  If the receptacle shows evidence 

of charring, we recommend that you do not make electrical connection.
