Shore power question

[Nick Badame Refrig/ACC]

Hi Bob,

If your bus is wired for 50amps, then you need the "Nutral" position in your feed. Not just the outlet.

Your nutral is there to ballance the load between both legs.

Some more scamatics here

Wow did i open up a can of worms again.

I was thinking that the 30 amp pulg adapter i have only has 3 wires and the dryer plug has 3 they would be some what compatable now i understand that I can't run the 4 wire system off of a 3 system.  I better throw that adpter away before i mess some thing up.  I wonder why they make them if they are so dangerous.

I guess the wife is about right I should trade this bus for a pickup and go back the the AVION.

Bob...your case, you are running 220/230 set-up...not like what some others RV'er is using same plug configuration with both same phase 110/115 lines. In other words, Line1 and line2 (180° out of phase) 220/230v or Line1 and Line1 (same phase) combine into 110/115v but more available ampere.

Yours is the normal Line1 and Line2 for 220/230v power.

Only danger is if anyone has a RV using Line1/Line1 and plug into 220/230v power source or pole wills results a possible smoke and/or fire if RV is set-up internally to make it happen.

You should be OK except with Ground fault interrupters set-up that need the forth wire.

FWIW

Sojourn for Christ, Jerry

I replaced an inverter for a friend that has a MC-9. He plugged his 30 amp cord into his niece's dryer outlet. He instantly let all the smoke out of his inverter.  Just be careful and be sure to check voltage at the bus with a meter before plugging anything in.  Jack

Definitely DO NOT plug a 30 amp RV Plug into a dryer outlet.  They are not the same thing.

It shouldn't go in anyway if the dryer outlet is using the correct 3 prong outlet.  Notice in the photo that the third prong is an "L" shaped prong, not an round/flat like on the 30 amp RV plug.

Since it sounds like the third prong of the dryer outlet could potentially be going directly to ground rather than bonded to neutral at the distribution panel, I fully agree that an electrician should probably do this. 

Or for what you're trying to do, just use two 12 gauge contractor cords.  Plug them into house outlets on different circuits.  Run one cord directly to the microwave and the other directly to the one burner cooktop.

I'm with HTR - you shouldn't be able to plug a 120v/30amp pigtail into a 220v dryer plug of any type - FWIW

Hey Bob,  is there a 100 v air conditioner plug in your home. The local Harbor Freight store has 8 ga and 6 gauge extension cords. Check your circuit breaker panel and see if there is a 30 amp breaker. Normally these are on dedicated circuits. Turn it off and see what goes off, if not marked. That circuit would give you enough power to run bus. call me if you need to. Big John
