Anyone familiar with converting 3 phase to single phase? (regarding a Blodgett commercial convection oven).?

i have only seen 120v motors in these ovens to be sure look @ the motor id plate. if this oven uses electric heat instead of gas the elements will be wired for 3 phase power and could possibly be converted check the wiring digram or intsallation guide

Check with several home heating specialists.  Recently talked to someone who just had NA furnace installed.  Requires no electricity.

That depends on the specific heat capacity of the oil and the amount of oil in the drum. A rough calculation could solve this assuming the drum is insulated and the amount of water is small. \nEnergy required=mass of oil (kgs)*specific heat capacity of oil (J/kg/degrees)*70 (degrees celcius)\n\nI have used 70 here assuming 20 degrees celcius room temp and assuming you are talking in celcius also. If not, you must convert 90 fahrenheit to celcius and take away room temp.\n\nNow convert 30 minutes to seconds; 30*60 = 900 seconds\nSo you want the energy required to be delivered within 900 seconds, therefore the power you need in watts is the energy required divided by 900.\n\nThis heater power will work in ideal conditions but should be increased (maybe by a factor of 2) to account for assumptions.\n\nI don't know how oil heating works (Don't blame me if you explode!!!) or what "heater capacity" means but I hope the answer in watts will help you.

first...identify the power source (AC or DC)\nthen...isolate the power source (lockout)\nnext...verify the circuit is not live (test)\n\nfinally...if it is AC three phase reverse any two of the three motor leads, if it is DC just reverse the two leads (if shouldn't be DC)\n\nif it is a european piece of equipment the wires should be black-black-brown, swap the blacks\n\notherwise, it should be brown-orange-yellow or black-red-white\n\nDO NOT ATTEMPT IF YOU ARE NOT QUALIFIED\n\ngood luck

You must understand power in = power out.\nSo the P(in) = 200A * 240V = 48000Watts \nTherefore, to obtain 400A out put you will sacrifice the voltage which will = 48000/400 = 120V\nYou need a heavy duty Transformer which will handle the 400A. The wiring size is 500MCM wire. Which is usually bus bar in a cabinet.\n\nTypically 240V 3phase line to line on a delta-wye Xfmr can provide 208V line-line provides 120V line-neutral. (208/sqrt3)\n \nUnless you have a Xfmr to convert, another way would be to use an active inverter, IGBT controlled.

At my job, I maintain lager equipment and small equipment for Land O’ Frost. We have motor that we use variable frequency drives on. The VFD’s range from 480VAC 3 phases to 24VAC single phase on the input side to 1000VDC, 480 single phases, 120VAC on the output side. But when installing a VFD the thing that are considered before installing one are the size of the motor 5hp, 35hp, .25hp, how many amps are needed to run the motor and peak amps so the parts are not over current. The voltage is another thing, the amount of programming that you can do so you can set limits for everything. It can take a long time to find what you need. Have fun shopping

How about this one?\n\n"This calculation module allows you to quickly calculate fault currents for a complete radial system. It can simultaneously handle a main distribution transformer, service lateral, second transformer, up to 40 main-feeders, with 8 main-feeders having 40 sub-feeders for a total of 360 nodal points. \n\nAccommodating both single-phase and three-phase circuits, the module will calculate from either infinite or known fault current values at either the transformer or the main-bus. \n\nThe module accommodates multiple conduit types, bus types, multiple conductors and motor contribution. The program is based on the popular LICE (point-to-point) calculation method. \n\nOur unique Help file (of which we are quite proud) includes complete practical guidance on Fault Calculations, and even includes a theoretical derivation of the LICE method.

Not sure I understand your question, but I think you could just parrelel it with your existing fan, instead of taking it off of the circuit board.  That is what I did when I added a duct booster fan to a long heat run in my house.  Those just have a fractional horsepower induction motor on them, so they dont take much electricity.

The addition of a neutral wire with a three phase electrical supply allows a lower voltage, single phase sub-assembly or appliance to be powered by the same line in (one phase to neutral).\nThree phase alone merely conducts between phases.

There are four examples of this wiring can be solo.  One is\n  from an existing source in points, a service truck.  So the server\n  may be set to use various voltages.  Second in this venue\n   for various temporary plugs of high services, i.e. refridgeration,\n   cold air conditioning, this may be a coaxial issued job.  The\n   next two are more likely an audio system with replacement\n   voltage, or an audio and television system with conduit fully\n   arced.  IF you have these last two jobs yes individual coduits\n   though every piece must be labeled and presorte so the link\n   in unavailable to the public, or the service worker, these are\n   usually fuse boxed and main fractioned.

changed all my light bulbs to low wattage, never turn lights on til absolutely necessary, never leave mobile phone cgarger plugged in (costs approx £10 a year if you do), I don't have a shower so bath/stripwash alternate days, have a hippo bag in the toilet cystern which saves approx 2 litres of water every flush, when running off water from cold tap keep a jug handy for 'waste' water, any spare boiled water gets saved in a flask for coffee, washing up etc (saves running the hot tap off til it's hot), never use the washing machine unless I have a full load, use half the recommended quantity of washing powder or tablets, never run machine above 50c, always do washing overnight on economy meter,  turned down the immersion heater, use the microwave/steamer daily, only use the oven when it's full,  batch bake and freeze (remember to take food out of the freezer to defrost naturally, not in the microwave), always buy meat, fruit and veg  from the market (it's fresher, cheaper and saves on packaging, therefore a drop of oil on plastic) plan car trips so that I do everything at once, ie visit the post office, do shopping, go to recycling centre etc, try to stick to 55mph for best fuel consumption, buy most of my clothes and small gifts from charity shops (but don't tell my family <blush>) recycle envelopes by sticking home made labels over the old address, recycle gift wrap, make my own gift tags from old cards with pinking shears, a hole punch and some thread from my needlework box, have stopped junk mail even if it only saves a twig a year, don't buy the latest cleaning products with this and that extra additive, my house shines on vinegar, salt, beeswax and recyled cotton clothes for dusters, etc etc etc....I guess you could  say I've made a few changes to my lifestyle!

In order to use the generator more effectively a phase is spli into three namely R,Y,B. each 120 phase shift from other.\nThe power generated is transmitted by 3phase-3 wire system considering economy.\nIn distribution side there are low consumers for whom Single phase power feeding is inhalf. For them a seperate cnductor called neutral is provided ad a return path.\nNeutral also helps to balance the load during unbalaced loading/fault.\nNeutral is a point that is taken from the meeting point of three phases and is usually grounded to ensure balanced loading.\n\nIn dc +ve side is something where excess protonsr present and flow towards otherside and -ve side contains full of electrons which flow towards +ve side.\n\nu can visit www.play-hookey.com

Yes check out this page http://sadoun.com/Sat/Products/Invacom/Invacom-QPH-031-Quad-lnbf.htm\n\nThe lnb has 4 outputs. 2 linear and 2 Circular. Not sure of the size of dish that you will need though.

Very simple....buy the same size and model as the old one, turn off the power/gas to the old one. Disconnect the old one from water/electric lines, and take it out. re connect the new one exactly as the old one was. Turn on power/gas.....if it is gas, light the pilot. Voila! you are now a master plumber and saved yourself a bundle. You will be surprised at how easy it is.

Using 3 phase current, it is possible to get 3 times the energy down the same wire - so it is much more efficient.  Each phase is 120 degrees out from the others, so the signal looks kind of like braided hair, when one phase is at the peak, the other two are crossing at 70%, one going up the other going down.  Once we get the energy to where we want to use it, then we can tap off the different phases for single phase use. \n\nI forget about the delta and wye stuff, it's been a while. \n\nCheers!

230v is measured between phase and neutral therefore L1 (R) N, L2 (Y) N and L3 (B) N.\n\nNote a star connection is Y. In your house you use 230v-240v single phase, i.e phase and neutral. Phase to phase 240√3 = 415v.
