'Boosting a' 110 V Electric grill - idea?
My Sunbeam 110 V electric grill works OK but it glows only faintly red
and it takes a while to grill a steak. My clamp-on meter shows 12.2 Amps. I imagine this mod: Connect a 220 V infinite range element controller (15 Amp at 220 V capacity) and output it to the 110V element. Adjust to a mild red color. Grill . What say you? BoyntonStu |

BoyntonStu great heat till the element burns out you might check about adding a second element somehow, providing 240 volts, providing 120 to each element. wouldnt t be easier to buy a cheap propane grill? |

If you are using an extension cord: I suggest measuring voltage across the line at the grill's plug and at the outlet that your extension cord is plugged into. If you lose more than just a few volts, get a new extension cord. Get one with as heavy a gauge of wire as you can find (preferably AWG 12, rated for 20 amps), and in the shortest length that you can find that will work. Volts dropped with 12.5 amps at wire temperature 30 C: (Note - remedying a voltage drop will increase your current slightly! This is why I am using 12.5 amps rather than 12.2 amps.) Feet is length of cord, and volts dropped is "round trip drop", considering copper wire length of twice the length of the cord. AWG 25 ft 50 ft 100 ft 16 2.6 5.2 10.4 14 1.64 3.28 6.56 12 1.03 2.06 4.12 These figures are only approximate, since wire has a tolerance in cross section area, and stranded wire usually does not exactly match an AWG number. I would change the extension cord if this will reduce voltage drop by more than 3-4 volts or so. Also, if you are using 16 AWG extension cord, I consider its typical 13 amp rating not as conservative as the 15 amp rating typical of 14 AWG extension cord. For "equal conservativeness", I would use a 16 AWG extension cord with no more than 11 amps. I also doubt any decent 100 foot extension cord comes in a gauge thinner than AWG 14. - Don Klipstein ) |

Bare nichrome wire can glow orange, but a heating element other than bare nichrome wire should generally not get past "dim side orangish red" that an electric stove "burner" does, and some may be limited to lower surface temperatures still! If you want to check the effective voltage across the heating element while it has current or effective voltage adjusted by anything other than a "variac"-like device or a true rheostat (extremely unlikely, also would make close to enough heat to cook with), your RMS voltage reading will read erroneously low unless you use a "true RMS" voltmeter. And if the voltage across the plug of your grill according to a true RMS voltmeter is above 125-126 volts or something close to that, I suspect 132 possibly but tops, then the UL listing of your grill does not apply, and your fire insurance company can give you grief if they have to get involved with anything related to this. For that matter, your booster may turn your grill setup into an "experimental apparatus" lacking benefit of UL listing from the get-go! You have to turn off the lights to see it.

Logic follows that it should also glow the same color as the oven element without premature failure. BoyntonStu |

'Boosting a' 110 V Electric grill - idea?
I have an electric turkey fryer and it
has similar problems, though the elements can't glow red because they are submerged in oil. The problem is that when you dump a room temperature 16 pound bird in the 400 degree oil, it immediately drops to something like 260 degrees or so. With the electric fryer, it never really recovers as it does in a mega-btu propane fryer .... but the electric isn't as dangerous. It is much better to fry the bird at somewhere over 300 degrees for best results. Anyway, what I would do is try in your case is a 220 volt Variac and adjust the voltage as needed. There are electronic ways to controlling the element, however, you might be able to borrow a Variac to try it as an experiment. In my case this would be a problem as the control is electronic. I wouldn't try a higher voltage unless the control could be isolated on a separate 110 volt connection. I do, however, have 2 elements units and I will try to put both in the fryer together, powering them from 2 separate circuits.

Also, the idea of a 15A 115V Variac going to 140V is another good idea. |

Small fixed adjustments can be made using a standard step down transformer. Wire the secondary in series with the primary and the load. If you get it backwards, it'll subtract instead of add. a 12V transformer will give you 132V out from 120V in. -----120V in------- | | +-----primary------+ | | | |--------- | | | -secondary-- | | -- load ------------- But remember, the secondary of the transformer must be capable of the load current. A 12 volt transformer capable of 15 amps will get pretty large. ****. I wasn't thinking of a 1500-2000W application. There's no way an inexpensive stepdown transformer will work. That's very different. never mind. /emily latella SUCCESS!! Here's what I did. I bought a 240 VAC Jenn-Air infinite controller for a range top burner (eBay $5.00) There are 4 contacts: 2-Line in and 2-heater out. I installed the controller and a pair of 115 VAC socket connectors pulled from old PC's onto a panel. The HOT (black) from each connector goes to a LINE connector. Plugged in a pair of extension cords from the opposite side of the panel (measured 240 VAC black to black) and used the PC power cords to connect. It works just like a dimmer. At 50% she glows red hot and it control cycles on/off to maintain the temp. Cheap, easy way to control a 110 VAC heater element with 220 VAC. It works better than expected! |

The element is running at about 140 VAC equivalent. AFAIK Europe uses 220 VAC. Your mileage may vary. |
