1.  LX - Troubleshooting Overview 

Problem 

No power at plug 

Cause 

 

Tripped breaker or GFCI 

Solution 

 

Reset circuit breaker in main panel or the GFCI usually 

located in a bathroom, garage, or kitchen. 

Problem 

GFCI keeps tripping 

 

Cause 

 

Ground problem or defective GFCI 

Solution 

 

Use a high-grade model such as the Hubbell #GF5252I. 

Problem 

One cable run not 
working 

 

Cause 

 

Cut cable or short 

Solution 

 

Test cable for voltage. If none, it is cut. If there is very low 

voltage and the cable is hot, there is a short. Check all 

fixtures and splices for defects 

Problem 

Lamps are burning 
out prematurely 

 

Cause 

 

Excessive voltage at lamp 

Solution 

 

Drop the affected cable run down to the next lower voltage 

tap or increase wattage load on that cable to drop voltage. 

Also, some lamps are rated for a very short life such as the 

4414 (300 hours). Use halogen lamps. 

Problem 

The closest lamp to 
the transformer is 
burning out 
prematurely 

 

Cause 

 

Excessive voltage at lamp 

Solution 

 

The closest lamp will always have a higher voltage reading 

than the last lamp. Cable fixtures so that there is about 40' 

from first to last within a lighting zone. See system layout for 

details.
