Extension cord

[Kevin D Pem]

Y’all need to stop comparing penis size.
No one gives a damn…

A 30A camper does NOT require 30 amps to run any particular appliance, system, or light.
A little common sense and possibly an error or two will let the OP know what he can run off his 15-20A circuit.
Stop with all the theory and bad breakers, extension cord size, etc.

Wow! Never thought about that! Is that a thing?

Wow! Never thought about that! Is that a thing?

guess we need to be more sensitive when comparing notes….

I find it is easy to use the features on this forum, guess some don't! We resolved this without disrupting anything, and those that didn't want to follow didn't have to.

All in all, I would call it a victory!
If you don't speak your mind, no telling what you would condone by staying silent!

I want to be able to plug my Coleman lantern Lt 17b into my house while loading or unloading and cleaning. I don’t have a 30 amp receptacle, I have the 50 to 15 amp dog bone What gauge extension cord would be good for this?

Since you're using a 50A-to-15A dogbone adapter for your Coleman Lantern LT 17B, you'll want a heavy-duty 12-gauge (12AWG) extension cord for safe operation. A 12-gauge cord minimizes voltage drop over distance and can handle the load of your RV's systems while loading/unloading.If you need recommendations, islewire’s products are a great choice (I’ve used them before).

Time to dispel any myths about breakers! These reset_able fuses will only fail fully on if they are not rated for the voltage applied. (For another thread)
We know that a fuse will blow when you demand more power than the fuse wire can handle. Open is failed.
Breakers use the same scheme. But rather than the element burning up it heats up a low melting point substance, like wax, that releases the mechanism that breaks the circuit. Resetting the cog with the breaker lever reastablishes the contacts(the reason you have to fully turn off the breaker when you reset it).
The melting point of the "wax" will never change, nor will the resistance of the heater. Any change will result in a Open at a lower amperage, never a higher amperage. One more thing! The heater is in series, therefore if the heater burns out the current will not flow in the circuit.

Hope that helps calm your nerves a little!

Kevin you are correct about the hydraulic circuit breakers and how they work, Primary manufacturers are Leviton and Phoenix. Most circuit breakers are mechanical thermal magnetic devices. The thermal portion of the circuit breakers or overload protection is accomplished by the us of a bi-metalic strip the deflects as heat builds up. The deflection of the bi-metal moves the trip lever to contact the tripping mechanism of the circuit breaker resulting in a trip condition, The magnetic or short circuit portion of the circuit breaker senses a short circuit and builds a magnetic field which pulls the trip lever connected to the tripping mechanism of the circuit breaker again resulting in a trip condition
