You can buy the cables from Blue Bird at 800/495-7787 or make your own. The best locking receptacles costs about $90 and high grade 30 amp, type 3 stranded wire cable should be about $7.00 per foot. Most Birders seldom use the two cables because there are very few times when two 30 amp campground outlets are back to back. Each 30 amp cable serves a seperate leg of the coach wiring so both cables need to be connected to get power down both legs. A single 30 amp outlet is the most common power source in campgrounds and the easiest way to deal with the situation and get power down both legs is to put a 30 amp adapter on the end of your 50 amp cord. Blue Bird sells a "cheater cord" which has a 30 amp plug on the hookup end and a 50 amp receptacle on the coach connection. Price is about $230 for the cheater. Two 30 amp outlets supply 7,200 watts of power (30 amps X 120 volts)X 2 wires = 7,200 watts as compared to 12,000 watts supplied by a single 50 amp outlet which by definition contains two 120 volt supply wires(50 amps X 120 volts) X 2 wires = 12,000 watts. I mention this only because there is an impression two 30 amp cords equal 60 amp service and supplies more power than 50 amp service. But 50 amp service divided between two 120 volt legs is really 100 amp service (100 amps X 120 volts) = 12,000 watts.

Author: HR Skillern [ Edit \| View ]	Date Posted: 12/ 14/ 01, 7:05pm At Camping World, one may purchase a short (18 inches) adapter that will allow a standard 30 amp power cord to be plugged in to the 50 amp receptacle on the bus. The item referred to is made by Marinco, I believe, and retails for about $80. I have used mine for several years and can report excellent results. Good luck. [ Post a Reply to This Message ]
