Topic: 50 or 30 amp Posted: 31 Jan 2019 at 4:01pm |
I used to live in a neighborhood filled with 80 to 100 year old Monterrey pines. When the wind got going during a rain storm, it was common for them to break about 2 meters up from the ground. I saw and heard several fall. It's not like the lumberjack cutting a tree with an nice key and a slow fall. Within one block of my house, over the years there were several fatalities from the trees falling on houses.
Moral of the story, it's better to match your conductor capacity and breakers even though the instances of fires are relatively rare. Being trapped in a burning Pod doesn't sound like a very pleasant way to go. The cost of putting in a breaker in the 30/50A dogbone is much less than the cost of starting a forest fire or your own funeral. Ask PG&E about the cost of electric conductor fires. Just a thought from a lay person. This has been a very informative discussion.

The fact that they have not, and again, the complete lack of any data points I can find about occurrences, says it's a non issue.
Like walking in the woods.. a tree "can" fall on you.. but it doesn't happen often enough to keep us out of the woods..

Unless you can get you hands on some positrons it’s going to be pretty hard to damage any electrons. And the violence of electron-positron annihilation is not going to meet the forum’s guidelines for civil behavior.
I’m probably missing something but I would think it would be pretty easy for one of the RV EMS manufacturers to add this functionality.

+1, thinking same here. The scenario for the risk has not made industry look at that solution. At least not anywhere I can find it.

Offgrid and GlueGuy,
Actually we are not in disagreement, there is a scenario where there could be an issue. A problem in the power cord that would cause the circuit to exceed 30As and be less than 50As. That has been on the RV interweb for quite some time.

I'm tempted to design a 50A-to-30A adapter with a built-in 30A breaker. That would solve the fire hazard issue with the wiring between the pedestal and the main breaker in the Pod.

Let's not get violent! I can't imagine the number of electrons that might be harmed!

Offgrid,
+1. Absolutely agree with this statement from your post:
"If the load currents are 30A or less and the combined fault and load currents exceed 30A but are less than 50A then neither the park's 50A nor the pod's 30A breaker will trip, but the 30A rated conductors up to the fault location will overheat. That is where the fire risk lies."
That is spot on to where a fire risk exists.
