As such, you cannot safely get 120 volts out of it without using a step-down transformer. Using ground as neutral is not safe and is not allowed by the electrical code. If you had a 240/120 volt outlet such as a 14-20, then you could safely make a splitter to two L5-20 using one hot and the neutral to each (as well as ground, of course).

Each single phase transformer would be wound 347 to 120 turns. The 347VAC secondary would have 120 turns; the 120VAC primary would have 347 turns; each times the number required to handle the kVA Remove the power cord by unscrewing the connections on the terminal block on the circuit board. Then remove the jumper wire from the "Red AC" section. Move the number 10 dipswitch down and that converts it to 240v. Your electrician will then bring in the neutral, 2 hot wires and a ground wire and you are good to go. 1. Cut off about 4" of the exposed 8" of unsheathed wire. 2. Strip the about 1/4" of insulation from the wires and solder them to the positive and negative terminal strips (see the attached image for the polarity of the cable) 3. Re-assemble the terminal block and install it into the top half of the battery cover. Show activity on this post. If you need 3-phase, 208V for just one 3-phase motor, you can buy a variable frequency drive (VFD) that will accept 120 V, 1-phase input and provide 208V, 3-phase output and control the output voltage and frequency to provide variable speed. It is simple in the sense that you just buy a single product and connect it. Although this is not recommended, it can be done when things are needed. For me this is a light load, and its also used seldom. so I'm totally happy with th fSsRpm. Electrical - AC & DC - Converting 240V dryer outlet to 120V outlet - Hello, Stumbled across a nice deal on a 2yr old Whirlpool gas dryer so I decided what the heck I'll install it. I currently have a 4 prong outlet for my electric dryer. I know it'll be fine to use the existing 10 gauge wire and swap in a single 1. Cut off about 4" of the exposed 8" of unsheathed wire. 2. Strip the about 1/4" of insulation from the wires and solder them to the positive and negative terminal strips (see the attached image for the polarity of the cable) 3. Re-assemble the terminal block and install it into the top half of the battery cover. The same exact rules apply to 240V circuits (no neutral) except you use NEMA 6-15 and 6-20. The sockets are almost identical but are keyed not to fit NEMA 5. You could take a 120V circuit and just convert it to 240V by changing all the sockets to NEMA 6 and landing its 2 conductors on a 240V breaker. First, it is important to understand the basics of the available power. 480V 3-Phase power involves three individual legs of power at different voltages, typically designated L1, L2, and L3. Each of these lines is 120V relative to each other, and they sum together to be 480V. When transforming this power to 120V, the goal is to balance out the Specifications. Quality fully-enclosed stepdown transformer with fold up metal carry handles, approved 3-wire power cord & US style 3 pin 110 - 120V socket (which also accepts US style 2 pin plugs). Up to 120 watt output. - Useable with precision electric & electronic appliances. - Compact, excellent, safe and robust construction - steel case. I spoke to my contact at Valterra and found that the # A10-5030FBK steps down a 50 amp service receptacle (2 X 120VAC) to 30 amps supply. This would work great for your camping trailers electrical system. I have linked the above mentioned product to this page for your convenience. expert reply by: Jackie C.
