Minor change to the introduction. It is not necessary to analyse asymmetrical faults using symmetrical components, it is just much simpler. Scoasty (talk) 00:33, 3 May 2011 (UTC)[reply]

Ungrounded housing fault? Also, neutral fault?[edit]

What do you call a fault to an UNgrounded housing?

For example, a 1950s toaster that has no grounding wire and a metal exterior. If that exterior is electrified, it's not a short ciruit to another node nor to ground (at leaat until a person touches it).

Is that still a grounding fault?? That doesnt seem correct.

One could argue the technicality that under today's code the exterior should be grounded. Okay, but what would you have called the fault in 1950 before that code existed?

Likewise, if the exterior is connected to neutral (not sure if this is/was ever an intentional thing or not. Seems like a bad idea, but ive heard some switches may have been like this) and the user plugs the 2 prong plug in backwards. What wouls that fault be called?

And what would one call the fault when neutral touches the housing (unintended)? Skintigh (talk) 16:30, 16 October 2023 (UTC)[reply]
