![]() Normally grounding a device via the neutral wire is not allowed. They will probably advise against it.Dryers with three-prongs are grounded using the neutral wire, when hooked up correctly (see answer for info on how to do that). The advice to call an electrician is sound. Measuring between the neutral and either hot wire will read 110V. In a 4-wire plug (which most new installation are), there are 2 hot wires plus the ground as in a 3-prong but there is also a separate neutral wire. You therefore get 220V across the 2 110V wires. The 2 hot wires are 110V each on opposite phases. You dont want to injure anybody.Ī 3-prong US drier plug has 2 hot wires and a ground. ![]() Suggest you call an electrician and hear it from them. ![]() OP, given you are getting conflicting advice here. Not a standard 3 prong plug running 110v. You may find appliances may also support dual voltage.īut the OP is asking about plugging into a 3 prong dryer outlet. They work but dont heat as much or turn as much. I've also plugged a 220v hair dryer, drill and kettle into a 110v standard plug socket. Sure plugging a 220v appliance in a 110v standard usa socket may work. Unlike the UK which has 1 (one) 220v positive, 1 (one) neutral and 1 (one) ground.Įxplain to me and the OP how you can wire up the 110v lines to make 220v? Twisting them together willnot work. VOD-1000(2-Way) Step Up Down 110220 Voltage Converter Transformer,1000 WattĪ 3 prong usa dryer outlet has 2 (two) 110v hot (positive) wires and 1 (one neutral). For those, I used a transformer as you suggested. Anything with an electric motor may have problems due to the frequency difference but I've not had that happen.ĮTA: I also brought a laser printer, CD player and amplifier over. I have run a power drill, kettle, fan heater, a switched-mode power supply and a Dyson vacuum cleaner using my method. The only thing that would cause a problem is if the neutral is internally tied to ground (which it absolutely should not). All the appliance cares about is that there is 220V between live and neutral. You WILL blow up your coffee machine if you do that.Ī 3k or 2.5k stepup/down transformer will run you about $150. Here in the usa they run two 110v lines to make 220v. The transformer plugs into a 110v plugs socket and will up the voltage. I have a 220v Rancillio espresso machine and seperate grinder. In a coffee maker, probably not important but if it contains as clock which references this, the clock will run fast. It should be noted that this is not (in US terms) 'to code' and if it does cause a fire, your insurance will probably deny any claim.Īnother point to note is US power is 60Hz where UK is 50Hz. That way, my appliances were properly protected. I used a UK fused extension lead similar to and replaced the plug with a drier plug. If a fault occurs in the coffee maker, it will probably burst into flames before tripping the 50A breaker. Without that fuse, it will be protected by the 50A breaker. The UK plug contains a fuse (probably 13A) designed to blow if something goes wrong. ![]() However, just putting a drier plug on your coffee machine will be dangerous. If an electrician is recommended that’s fine - I have no intention of doing something way out of my depth! But a simple rewiring of a plug is within my capabilities!ĭepends on the appliance but it will, most likely, work. The coffee machine manual says it MUST be grounded (running at 1250W I guess this makes sense).Īny help/advice much appreciated. My question is, is it possible to change the plug on the coffee machine to work with the 3 prong dryer outlet? It would be great if so! Being from the UK I have no prior knowledge of dryer outlets, but having done some reading I understand they have two hot and one neutral(also ground) wires. Whilst we still haven’t moved into our own house (staying in her mums house), we discovered a 3 prong 250V 50A dryer outlet in the kitchen. Given the prices of many many electrical appliances here, my wife and I brought over our coffee machine from the UK. I am actually living In Ecuador, but as my question is electrically-related, and Ecuador has the same power specs as USA, I thought I may get more responses posting in the USA forum. First post - limited electrical knowledge so excuse me for any ignorance.
