If the system is not modified, there is no requirement to bring it up to date. Perhaps the tech meant the grounded neutral in an old house is often inadequate, leading to the failure. If so, they could be quite right in this case. | |

| Mar 6, 2013 at 14:38 | comment | added | maple_shaft | @AricTenEyck Well your neutral connects to the center tap which comes from your transformer. It serves as a conductor for low voltage alternating current being generated by the transformer. Of course it comes from your power company because they are responsible for the transformer but then there really isn't anything wrong with your neutral. It is the homeowners responsibility to make sure that the neutral lines connected to the center tap have been grounded to earth ground. | |

| Mar 6, 2013 at 12:47 | comment | added | maple_shaft | @Tester101 If the ground is proper, has little resistance and shorts the circuit then enough current will flow to cause the breaker to trip. | |
| Mar 6, 2013 at 12:00 | comment | added | Tester101 | The equipment grounding conductor (EGC) will not cause the breaker to trip if a fault energizes an appliances chassis, it will however, give the electricity a safe path to follow. | |
| Mar 6, 2013 at 9:51 | comment | added | maple_shaft | @AricTenEyck Grounding your system to your water pipes is not the ideal way but it I do believe it was an acceptable way in the 50's. A corroded point doesn't make for good low resistance grounding. Try to replace the grounding point for a quick fix. | |
| Mar 6, 2013 at 4:45 | comment | added | Aric TenEyck | "Grounded neutral" was written in the email. But thanks for the info. My system is grounded to water pipes, I don't have a grounding rod. Though looking at the primary grounding point, it looks a bit corroded. (Replacing previous incorrect comment) | |
