can you run 208v on 240v

If heaters (Warren) are rated for 208V, why would a 240V system not work? Discuss please. A 230 volt motor running on 208 volts will run a slightly higher amp draw. The IEC receptacles will usually be IEC C13, which is also what is used on most servers (in the matching C14 plug). The output of the UPS is unbalanced, meaning that from hot to hot you will see 208 volts (or 240v if so configured), however it is not two balanced 120 volt legs as you would traditionally see from 208v/240v utility power. Even if it's not, any 240V-rated heater can be run on 208 at reduced power. The motor insulation is good for at least 600V, probably more. Reactions: Chipper5783. Most of my machines are single phase machines. Can you use a 208V 3ph rated commercial dryer on a 240v 3ph line? As stated earlier, the power that goes in must match that power that comes out without creating anything new. Therefore, the 208V elements will likely fail on 240V and that failure may be spectacular (very dangerous). Give the motor a full 240V before it starts. As you mentioned there are no cheap controllers for 240V. If it says 208-240V you could have it wired to the service panel if the panel rating is big enough to handle it. or total watts the element needs to be, I may be able to recommend a cheap big box home center solution. I just googled and some parts of China have 220VAC @ 50hz. I actually have Many manufacturers sell both options. However, a 208V-only heater on 240V will run at 33% higher power and this could cause overheating. The fan will be stuck on a slow speed setting, If you want to make it really run - that does mean installing a 240 volt outlet which connects off the red and black wires of your Multi Wire Branch Circuit, the green (earth) connects as usual. In this case the motor is overvoltaged by ~ +4% and that's fine. Do not plug it into a standard 120V house circuit. As others have said, check the nameplate or call the manufacturer. Most modern devices can support this, but you must check the nameplate of each device to be powered. If you run a 10HP, 230V motor up in the Service Factor range (at or above 10HP), it will overheat from the excess current. 1) There is no such thing as 220/240. The problem with using the 208V oven on a 240V circuit is that the heating element can draw too much current and overheat. 208v is found in industrial settings as well as 277v and 480 volt taps. This doesn't mean the voltage at the receptacle is 250V though. Warren is proud of their duct heaters. I like the bicycle analogy. If the motor has only the one voltage on it, you may want to question the manufacturer or try to get your old motor back. It sticks around because it rolls off the tongue so well.

If you can't get a 208 rated motor (or one which has multiple voltage ratings like 208-230, which are made) -- then you're better off looking to insert transformation to get back up to 230 volts; this could be a 2-winding transformer of 208-230 volts or else you could get three (3) buck-boost transformers (2 winding units configured as auto-transformers) to get you there. This limits starting capability. Like; Save; bus_driver. 1 - 4 of 4 Posts. It will operate assuming you have a 120/208V 3 phase system, but it will not get as hot as it would on a 240V system. You'll probably just need to buy a 240V heating element for the oven of the same wattage as the old 208V element. For example, 120v-277v will operate on any voltage between 120v and 240v. To wire it just use 2 hots instead of 3 and connect the neutral. The variation of +10% -6% permitted on the actual voltage received at a property covers this variation anyway. Tester101. So, what does the rating plate on it say? 12,412 Posts #8 • Dec 15, 2014. power said: I have ran into the same issue with one of our welders.

This limits starting capability. Like; Save; bus_driver. 1 - 4 of 4 Posts. It will operate assuming you have a 120/208V 3 phase system, but it will not get as hot as it would on a 240V system. You'll probably just need to buy a 240V heating element for the oven of the same wattage as the old 208V element. For example, 120v-277v will operate on any voltage between 120v and 240v. To wire it just use 2 hots instead of 3 and connect the neutral. The variation of +10% -6% permitted on the actual voltage received at a property covers this variation anyway. Tester101. So, what does the rating plate on it say? 12,412 Posts #8 • Dec 15, 2014. power said: I have ran into the same issue with one of our welders. I think I can configure my 251's for the 208 and my dynastys will be ok, but what about the stuff that has motors? 213 1 1 gold badge 3 3 silver badges 6 6 bronze badges. As stated most panels are rated for 250V so 208 would be fine. share | improve this question | follow | edited Jun 5 '14 at 10:08. Keep the actual motor load down to 80% - 90% of rated output and you should be OK (I'm figuring 208V is about a 10% reduction from 230V). You can generally apply +- 10% of this value to the equipment and still achieve normal operation. asked Jun 22 '12 at 14:22. If the device’s nameplate states that it can run at 208v (in addition to say 220v or 240v), you are fine. If a panel is rated 208V-- which would be unusual then you cannot serve it with a 240V line. But devices will fry if you run them at the wrong frequency. The machines I am worried about are my iron worker, my roller and my mill. Would a shared neutral cause problems (ie, addition of outgoing current) in the neutral wire? Sometimes the nameplate will state 208-240v as acceptable voltage ranges. If your phase converter is actually putting out 220V you should be fine, but I suspect if your power is anything like mine, you will be closer to 240V. In a house, you have two 120V supply lines of the same phase. Continue with Google. Can you run a 240V clothes dryer on a 208V 3-phase connection? Second, stepping 208V up to 240V is not tidy. Devices can run on a wide range of voltages, and often the higher voltage is better.. as it lowers the ampacity. 2)There is no such thing as 3Ø 110/208 3) There is no 220 in the US. 2. An electrician can advise you on this . Are the 2 hot wires still out 180 degrees, or is it 120? I run into this way more than I'd care to. 208V is part (two hot wires) of a three phase grounded wye system. (208V). A quad tap ballast would be marked 120v, 208v, 240v, 277v and would have to be set up for the correct line voltage. I’d like to point out that you are asking 2 possible questions: Is the system you outlined, a) a 230V motor on a 240V supply? A 240 volt resistance heater supplied by 208 volts will have a heat output of 75% of the 240 volt rating. Now if you are talking about a motor control panel then we have a different issue. Most newer motors will run 208-240 just fine. Continue with Facebook. Re: 3 Phase Motor Voltages: 208 vs. 240 … Save Share. As UK used to be 240 but dropped to 230 to match with France, France and all EU moved from 220 to 230 for same reason. If you want a simple understanding but aren’t electrically minded, start with a simple analogy you can build on. Running a 208V motor on 230-244V … 120/208 or 120/240. I would wire it up and put an amp probe on it, if the current draw is within reason, you should be fine. 460 volt motors are designed to run … I will be moving my shop soon and the shop Im going to has three phase power and 208 single phase. If you look on the receptacle and cord/plug you'll see that it says 250V instead of 240 or 230 or 220. Industrial installations usually have a 480 volt feed from the power company and the facility then has a step down transformer that delivers 120 volts for offices etc and 2777 for lighting. Radar. You may have some grounding issues. Running machines on 208v? Hi Kammy, First, let's get a minor detail clarified. No, you cannot get 240V when the transformer nameplate says 208V. 13 years ago. I plan to eventually run a second 240 volt outlet when I have the time and consider this a temporary solution. or sign up with email About this Discussion. It will operate assuming you have a 120/208V 3 phase system, but it will not get as hot as it would on a 240V system. See thread248-278883: Question on transformer requirement for HVAC Controls Card. If it's just 208V that requires 3 phase service which would cost more to have put in your house than a new 120V centrifuge. Many manufacturers sell both options. The 240 did not fry your motor, something else is wrong / broken. Can you use 240v on 208v motor? If you can specify how many BTU/Hr. The two output legs are 180 degrees out of phase and from hot to hot they will measure 208v or 240v. 208V Single Phase and 208V 3 Phase power are easy to use, but hard to understand. These will normally have IEC connectors for the input and output instead of the US 5-15R straight blade receptacles. It introduces a high-impedance into the circuit for starting a small motor. This means that during the high inrush current of the motor, a high line impedance drops the voltage. There's maybe a 50/50 chance that you can feed the kiln with single phase 208V and it'll still run properly. There are 10 types of people. 208V equipment 240V power help! Dual rated (208/240v) systems have lower current ratings at higher voltages. A tandem bicycle has two people providing power with four legs (pedals). You can’t get it directly, though there’s a lot of equipment rated for 240V (usually specified at 230V) operation, that will still function at 208V, though it will produce 25% less power at that voltage. Those who know binary, and those who don't. LED drivers and fluorescent ballasts marked with a dash between the voltage will function in that range. Canada/USA run at 60hz frequency.. it's incompatible. It can be tempting to use a 208V/240V-only power distribution unit. Since most Motorola equipment requires 120V, we need to split the 208V back into two 120V conductors – but it can’t be done. Join the discussion. I HIGHLY doubt you should have a 208v service to a residence. running 1 208v or 240v circuit to your rack gives you 2 120v circuits. There is no distinction on those IEC connectors for 120V vs. 208V/240V. Rob . Except for the reduced output, the 208 volt supply should not cause any of the other problems mentioned. If so I would assume it is wrong and should be corrected. Helping a buddy try to avoid a $1000 mistake. 124k 67 67 gold badges 288 288 silver badges 561 561 bronze badges. When you run 120/208V single phase power into an isolation transformer, the two individual hot conductors of 120V are combined into one 208V waveform. You seem to have your voltages all confused. Reply. In your breaker panel, you can install a breaker which grabs voltage from each bus, and you wire a standard 240V device - like a dryer or AC unit, etc.,. 220 is an archaic term left over from way back in the day.
