My company is a cooking equipment manufacturer that has recently installed equipment on a cruise ship. The equipment is electric with tubular heating elements. The issue is the elements are apparently tripping alarms on the ship because they are showing resistance to ground. Our element vendor has been of no help.
The service company had another manufacturer make elements that have solved the issue. The problem is this company will not share the information to the solution.
“The issue is the elements are apparently tripping alarms on the ship because they are showing resistance to ground.”
Probably the circuit breaker (if they were using one instead of fuse) exceeded its maximum current carrying capacity because the rating of that “tubular heating elements” exceeded the rating of the circuit breaker. They could have solve the problem without replacing that “element” unless that “element” was already defective. I could tell you how but I don’t know the specs of that “tubular heating element.”
