We are putting a fridge into an alcove that only had shelves

We are putting a fridge into an alcove that only had shelves in it. One side of the alcove is a wall which separates it from the rest of the kitchen (the stove is closest to that wall). The contractor wants to just put a hole through that wall to run the fridge power cord thru so that it'll plug into the same outlet that's behind the stove. Even if he puts fancy access covers on either side of the hole, this doesn't sound like it's up to code. I think he needs to have a real electrician put a new outlet in the alcove. Correct or not? Is there any other solution that would hide the cord and wouldn't require installing an outlet?

There is a 3 way exchange that you will need to read

There is a 3 way exchange that you will need to read for the context. What I need to know is: Will a transformer step up my voltage from 208v adequately enough for me to run my 220v espresso machine at, or very close to, 220v without making the espresso machine "work hard" to draw the power as Tim says? If so, which transformer would you recommend? Who is wrong and right, Tommy or Tim?MEI have a cafe space that has 200 amp 120/208v 3 phase 4 wire electricity. My espresso machine is rated to run on 220v single phase, 50/60 hz, 40 amp max draw, with a 50 amp cord plug rating. I will be hiring an electrician for this, but what will need to be done to get the correct electricityto the espresso machine and how much of my 200 amps will be taken by the machine after the conversion?TOMMYThe machine is rated at 40 amps, so he will be using a 40 amp double pole breaker to connect to a transformer which will increase the voltage from 208 single phase to 220 volts single phase. You might verify the machines nameplate, as some are dual rated for 208/230 volts. If so, it will be stamped on the metal nameplate. Since it is rated for 50/60hz, I would think it has a good chance of dual voltage rating, but not guaranteed. Check the nameplate to confirm. Increasing the voltage with a transformer to run the machine, uses no more electricity than wiring it direct if it was 208 volts, it uses the exact same power.METhank you Tommy. Can you give me a link to an example of a transformer that I will need? Will I also be able to run appliances rated for 110/120v directly from the panel, or will they also need a transformer?TOMMYYour appliances will have the 120 volts available, that is why you have the 120/208. The 120 portion is convenience receptacles and lighting. The 208 is for large equipment. I do have to make a small correction. The machine uses 40 amp breaker on 220 volts, so the 208 side will be a little higher to power the transformer with the lower voltage, but only at 48 amps, so they will have to put a 50 amp breaker in the panel and it will serve the transformer to supply the higher voltage at 40 amp.You will need a 1 KVA Buck Boost transformerSaves money over using a standard isolation transformer, since you only need to Boost the voltage a small amount(Interjection from ME in the present: I took this all to mean that yes, I could step up the voltage from 208 to 220 using a transformer. However when I got a bid from an electrician recently, he tells me a different story)ME (speaking to TIM this time)My understanding (which could be wrong) is that the transformer will allow us to run 220v and/or 240v appliances. I put this issue to an electrician on a service called JustAnswer.com and he gave me this answer (I show him the exchange I had with TOMMY from above, then ask) The espresso machine, for example, wants 220v. It is not designed to run on 208v. The transformer will allow you to step up the voltage to 220v for that specific circuit to run at 220v. Is that correct? If my understanding is correct, and the transformer will step up the voltage to 220v, why would we need to be concerned with equipment running at 208v? Can we use the transformer to step up all circuits that we need to run at 220v?TIMNo the transformer will deliver from the main service, which is 277-480 to 120/208. So if your espresso is rated 240, it's going to work harder to operate efficiently as designed at 240 volt , therefore it's better to have one designed to operate efficiently at 208 voltageMEThat makes sense when I take that information by itself. But in Tommy's answer to my question he either contradicts that or I just don't understand it correctly. When he says "The machine uses 40 amp breaker on 220 volts, so the 208 side will be a little higher to power the transformer with the lower voltage, but only at 48 amps, so they will have to put a 50 amp breaker in the panel and it will serve the transformer to supply the higher voltage at 40 amp." Doesn't that mean that the transformer is doing the hard work so that the espresso machine doesn't need to?TIMI think it means that the machine is trying harder but the voltage just isn't there. I do see what he means but slightly disagree. The voltage is the voltage that does not change, but I think what he's trying to say is that the machine will overcompensate the voltage by drawing more amperage, so instead of using 30 amps at 240 volts, you've made the machine stop at 208 volts, so to make up it uses more amperage or power, say 40 amps. Ultimately, get equipment that runs on 208. Most of them run on a range of voltage, which makes this conversation a moot point. Just check with the MFG. that's all. It's not this big deal, trust me.Back to ME from the present: The espresso machine is not designed to run on 208.

This is a commercial electrical question.I have a

Hello, this is a commercial electrical question.I have a medical equipment that's hooked up to a 4 pronged 240v outlet. The equipment has a label by the power cord stating that it requires 240V, 60hz, 30 amps.Long story short, we called the service guy for the equipment and he said that the outlet is faulty and that we need to call an electrician. He didn't state exactly what the problem is.I'd like to say that I'm very handy. I've rewired, installed new fixtures, and found open/shorts to circuits to friends, and neighbor's house in the past.I measured the voltages against the 4 prongs (all possible combinations) and in summary, depending on which two prongs you touch, I am getting 120V and I'm getting 212V (or 0v). However, when I measure the frequency/hertz, one of the hot wires was not reading 60hz (it was fluctuating between 200-300 hz).I have a 200 amp electrical panel that has 3 power lines coming into it. I took a frequency reading from each of the 3 power lines to ground and one of the three power line fluctuates between 200-300 hertzs, the other two reads 60 hz. I then measured the next two slots below when the existing breaker for the equipment sits and they both read 60 hz (I'm guessing it's because they go to the two power lines that reads 60hz). Btw, the frequency reading for two slots where the breaker for the equip currently sits reads - 60hz, the other fluctuates between 200-300 hz.So.... Naturally, to solve the problem I moved the 50 amp breaker down a slot and now it's reading 60 hz at the outlet (for all hot wires) and 120v or 212V (depending on which wires you measure against).My question is:- Is it normal to be getting a reading of 212V instead of 240V at a 240V outlet? (btw, I took measurements numerous times and never get a reading of 240V plus/minus 10V (i.e. 230v or 250v or even 230v)- What is typically wrong when one of the three power lines is producing an abnormal frequency (other than 60hz)?- Shouldn't all AC outlets be reading 60hz no matter what voltage it is?- The fluctuating frequency at one of the 3 power lines feeding the panel, could it be because the panel is bad? Or the fault is one the power company side and I should reach out to them to fix it?

I want to replace a kitchen trash compactor, but when I pulled

I want to replace a kitchen trash compactor, but when I pulled it out from under the cabinet I noticed the power cord disappears down into the floor through a hole sealed with spray foam. The previous owner must have remodeled and ran the cord down to link up with an electrical box or line somewhere else, obviously not thinking about how he might replace the appliance one day. Option one is to cut open the floor and trace all the connections and maybe install an actual outlet under the counter for this appliance. Option 2 is to simply cut the existing cord and splice it with the power cord of the replacement compactor and leave whatever is unseen untouched. This compactor has worked fine for the 4 years I've lived in the house and I'm buying a used replacement off Craigslist, so I'm not concerned about cutting the cord on the new one and any kind of warranty etc.

Installing a new Jacuzzi whirlpool tub with the optional heater.

Installing a new Jacuzzi whirlpool tub with the optional heater. Both the pump motor and the heater have there own 15A GFCI as called for in the install instructions. A 8AWG bonding wire lug is on the pump and heater. Do I bond just the pump and heater together? Or do i have to bond that to the house plumbing which is copper? Or is it needed at all?

I'm trying to replace our Maytag Neptune's power cord plug

I'm trying to replace our Maytag Neptune's power cord plug from a three-prong to a four-prong, so I'm reading through the previous post on the topic before asking questionsJA: Sometimes electrical issues that that you think will be really complicated end up being easy to fix. The Electrician I'm going to connect you with knows all the tricks and shortcuts. Tell me a bit more about what's going on so we can help you best.Customer: I figured out where the black and red wires go (either side of the top three connectors), and that the green goes to the ground (directly below) so the white wire goes to the center connector; I am just trying to identify where the bonding jumper is, because my understanding is that I must remove itJA: Is there anything else the Electrician should be aware of?Customer: the instructions I read previously also mentioned that I should shut off the breaker for the outlet before plugging the unit back in, then I should turn on the machine, then switche the breaker back on.JA: I'm sending you to a secure page on JustAnswer so you can place the $5 fully refundable deposit now. While you're filling out that form, I'll tell the Electrician about your situation and connect you two.

Kevin,This is Alnair again, if you remember me. I asked

Hi Kevin,This is Alnair again, if you remember me. I asked previously about my wall oven and cooktop electrical connection.I have another question. I bought a built in microwave oven and range hood. I have a dedicated circuit for microwave/range hood (where the old over the range hood was connected). The circuit was 20Amp, 3 wires-black,white,copper. The new built in microwave and range hood both have plugs, but one of the 3 prongs of the plug of the microwave is not straight but rather going to the side. I attached the picture. The plug of the range hood is a normal 3 prong plug. I attached the requirements for microwave and range hood. Let me know if I can still use this circuit for both appliance.Attachments:1. Requirements for microwave2. Range hood reqs3. Plug of microwave4. Wire of microwaveThank you so much!

I own LG Oven Range LRE3023 and we have problem connecting

I own LG Oven Range LRE3023 and we have problem connecting and using it in Bulgaria Europe. Can you advise how it need to be connected. The owner manual does not help ..its only a basic information how to hook the 3 wire power cord. We bought this with the only reason to use it there, but if we plug that in a 220 volt el swich will most likely burn the controler. What should we do to get it going. Thank you
