What is 40va?

What is the max secondary amperage for a 40VA 240x24 volt control transformer?

1.6

Can you substitute 12V. AC 40va Transformer for 12V. AC 1000ma. Home service-out door fountain?

Yes, the output current of a 40va transformer at 12 volts is 3.33 amps. The replaced unit had an output of 1 amp making it a 12va transformer. By doing this exchange there will be three times the capacity of the new transformer over the old transformer.

What IS power factor on 40VA 24VAC?

There is insufficient information in the question to answer it. You need some other information, such as voltage to current phase angle, inductance, capacitance, or watts. Please restate the question.

How many watts is 40va?

40 VA is the apparent power of the load. It is simply the applied voltage multiplied by the resulting current in amperes. Given the VA and the Volts merely divide the VA by the volts to get I=VA/A = 40VA/24V= 1.667 Amperes rms. Andy B

What could cause a 24 volt transformer on a house heater to burn up?

On the 24vac side, this would include any load attached or powered by the transformer. A wire than has gone to ground (shorted), or rubbed into the ductwork (stat wire). The transformer will be rated at xxva, meaning volts X amps aka(watts). Most residential equip. will have a 40va fitted. 40 / 24= 1.66 amps. Any load in excess of this should cause a failure. If you are trying to fix this yourself, put a 2amp automotive fuse in series with one of the 24vac "out" leads and go one by one, isolating the gas valve, wiring to the thermostat, etc, till the fuse quits blowing. Otherwise, call a tech. lc

What is the amp rating for a 208 Volt 100 VA transformer?

Is 120 V the primary or secondary voltage? If the primary (input) voltage is 120, then at full load the transformer will draw about 0.42 A from the line, and the current delivered to the load depends on the secondary (output) voltage. If the secondary (output) voltage is 120, then at full load the transformer will deliver about 0.42 A to the load, and the current drawn fom the line depends on the primary (input) voltage. amps = watts / volts So, for instance, if your transformer has a 120 V primary, and a 24 V secondary, as you might find in your AC unit or furnace: Primary current (at full load) - A = W / V A = 50 / 120 A = 0.4166 Secondary current - A = 50 / 24 A = 2.08

Is justanswers.com a scam?

Yes, I think so. I have had to hire a number of attorneys for various legal problems...divorce, military pension, family trust, high exposure trucking accident, custordy, and only one charged for an initial consultation and he was completely unhelpful!!! Essentially you are interviewing them for a job and an applicant doesn't charge for that! If the free answer was to try to pull clients in...that is an interesting idea and might and might not work. Who knows. But the low credit card fees tells me they are doing something else. Not sure what...but something else. Sometimes these scams just want your info to sell to marketers. Not illegal, but icky! I'm sorry to disagree but its not a scam. I started as a customer and ended up working on the site as an expert. I posted many questions and if it didn't get answered, I just emailed them and they refunded my deposit with no questions asked. I was shocked myself but seriously, no questions asked. They just refunded. I finally decided to become part of the expert community. Customers are not required to accept an unhelpful answer and that is the scam part. The expert spends time answering and the customer reads it and never accepts leaving the expert without payment. But its worth it in the end. IT IS ABSOLUTELY A SCAM and I'm not even sure of whether or not it is legal. There are numerous ethical violations on the surface and I assume even more if you drill down into case study. First off, there is a serious "attorney/client privilege" issue considering all questions are posted for public consumption. Any attorney worth the paper their degree is printed on knows better than to engage in the disclosing of their legal opinion in a public forum. I have found numerous erroneous statements about particular companies which, if those companies ever get wind of this website, will cause the site owners as well as the attorney themselves serious legal issues which include being disbarred. After reviewing some of the attorney info and doing additional research, I have found at least 7 of the approximately 10 that I researched have significant malpractice lawsuits against them. It is clearly obvious that the site creator Andy Kurtzig thinks he found a loophole and has carte blanche to openly provide legal advice which is likely going to land him and anyone affiliated in legal hot water once the courts get their heads around the legalities. If this were a site where you asked a question and an attorney responded in private, then I'd say they are actually trying to provide a legitimate service. However, due to the fact that these are "opinions" by some of these less than ethical attorneys, I would tread lightly when considering any information from them as many of the "answers" I read are slanderous and inflammatory and if they anger the wrong company, they are going to be hit with defamation lawsuits which will involve the unsuspecting consumer who asked the "question" and both will be considered liable for damages. http://tinypic.com/r/344bf2r/6 phil <a href="http://tinypic.com?ref=33fg6lk" target="_blank"><img src="http://i48.tinypic.com/33fg6lk.jpg" border="0" alt="Image and video hosting by TinyPic"></a> I am leaning towards the new EIM you got was faulty if you have everything wired as instructions show,that buzz just should not be there.The VA is volt amps that a transformer is rated at you could actually install a 75 va transformer inside the furnace where the 40 va is now.but it seems unlikely that the EIM is causing the need for a larger capacity transformer. I do believe you need a new EIM but it is possible the old transformer is weak. if you have an amprobe you can twist your w wire going to furnace around a screw driver ten loops pull the screw driver out and hang the amprobe around the wire turn the unit on when the call for heat begins read the amps it draws if anything close to .40 replace the transformer.Its the unit of electrical load being used you know if the full load was being used that the transformer produces,it would blow the fuse in the furnace control board or overheat the transformer. rpen7111 THE 24V GROUND IS THE 24V COMMON!!

What was your model number Customer replied 120 days and 6 hours ago. Billy, I just returned from an out-of-town trip to find the house stifiling hot. Apparently, the furnace finally decided to respond to the 75 degree setting I had left it on during testing. This situation is so baffling. When I rhen reset the thermostat to a reasonable setting, it was back in it's old routine of cycling on for a few seconds only. Apparently it is capable of working properly sometimes, without any apparent change of conditions. Having replace the board, flame sensor, and gas valve, and grounded the hell out of everything, we're no further along with this. Did you ever get a chance to forward my problem to other more experienced experts? Tim Hello, I'm a moderator for this topic. It seems the Professional has left this conversation. This happens occasionally, and it's usually because the Professional thinks that someone else might be a better match for your question. I've been working hard to find a new Professional to assist you with your question, but sometimes finding the right Professional can take a little longer than expected. I wonder whether you're ok with continuing to wait for an answer. If you are, please let me know and I will continue my search. If not, feel free to let me know and I will cancel this question for you. Thank you! Rachel Customer I would like an answer to my question, but I must insist that whoever takes over familiarize themselves with my previous communications on this problem as I've been struggling with this same question for SEVERAL months and do not want to cover ground I've already covered. If we can't get an answer sometime soon, I'm going to have to break down and bring in someone locally, and I don't want to have to do that. V12TECH This unit uses flame rectification, this is a DC signal of micro amps that returns to the ignition module via the modules sense/ burner grnd terminal . It transmits the weak DC signal to the module to prove a flame exists and is safe to continue operating . I did not see if the port on the induced draft assembly, where the induced draft proving switch's tubing connects was reamed out good? It will obstruct and cause a wavering pressure thus pop open intermittently which is difficult to spot, I don't trust the flash codes myself, as there are only several possibilities to rectify this situation . I have a routine I use for these , I clean the pilot assembly's mounting brackets surface areas and the burners surface areas touching the pilot assembly mounts, basically we are making a nice conductive path to home, being the burner grnd/sense terminal. In addition I use 105C degree rated wire and connectors and run a ground wire in addition to the units grounding back to the terminal that is used for sense or burner grnd, usually they are common in the circuit board. Remember it is only transmitting the faint DC signal that passes through the flame, a flame is a poor conductor and only transmits micro amps DC and that is easily stopped by a patina or moisture or corrosion etc, it does not take much and it is easily disrupted and restored. In fact many times new components seemingly rectify an issue, often the restoration of a ground path for the flame signal is really what fixed everything and if you try the old equipment, it is operative about 40% of the time according to manufacturers. Johnson controls makes a nifty flame simulator ($24)that simulates a nice DC signal that will work on any flame rectification system! it plugs in with the existing flame proving circuit and clamps to ground with a clip, If it wont run with this, no question the boards/module is defective, assuming all limits and safeties are closed, I often bypass them to test with them jumped to see what is going on..jumper clip the pressure switch once it has closed. For the pressure switches I use tattle tales to tell me if any control opens,even if a brief second, that is hard to spot unless gazing at it while it pops opens for 1 second , pressure switches on the threshold will waver and not be evident by watching , tattle tales have a flag that pops up if what it monitors trips or opens. You can by the and pressure switch for what a service call will be alone online and its very easy.Its not worth spending time troubleshooting parts that cost 10 minutes labor as in sensor and pressure switch and any auto reset limits. 1 yr of this is not worth this trouble, unlesss you had a $400 board i would sawp out the pressure switch, sensor limit and module, it wont be much online and if the pressure orifice is not clogged it will run no doubt with the system refurbished. I dont just replace a board and leave old cheap components there to fail next 6 months being a free call back and cutting my profits in 1/2. If a service tech is doing sub $300 service calls much he will be fired, go broke,etc. I had bosses tell me this in the early 90's.

Category: HVAC Value: $30 Status: CLOSED Billy, we've resolved the grounding issue that caused the furnace not to light, and I think I remember that everything was working OK at the end of last heating season. Now however, it behaves thusly: upon setting thermostat to heat and lowering the temperature setting below ambient, the ignighter succeeds in lighting the main burner, which runs for about three seconds and then cuts out. The blower comes on and runs for a couple of minutes until it realizes the burner is not longer running and then shuts off. This whole cycle repeats periodically until I shut system off at thermostat. Any ideas?
