My house has a 220v transfer box on my main breaker panel.

My house has a 220v transfer box on my main breaker panel. It was installed in 1999 and has a 3 wire Nema 6-20 plug. The original generator had a compatible female receptacle. That generator got stolen and I got a replacement: a generac gp5500. It has a Nema L14-30p plug. I am trying to connect things to make it work, as we have an ice storm bearing down on us. I have a male Nema L14-30p and a male Nema 6-20p, but my knowledge is tapped. What now?JA: What's the make and model? And can you guesstimate how old it is?Customer: Generate go 5500. Two years old. Tops.JA: Do you plan on doing the work yourself?Customer: Looks that way. Yes.JA: Anything else we should know to help you best?Customer: Different question, there.

I have some WeMo Insight outlets, that I hooked washing

I have some WeMo Insight outlets, that I hooked washing machine to. But I was thinking it would be great to hook my drying machine and dishwasher machine through them too. But drying machine uses large outlets - will some adapters work here? How about water heaters can I run them through or that of the dishwasher or they are impossible to hook to?

After running shower/water heater for 15-20 minutes it shuts

After running shower/water heater for 15-20 minutes it shuts off and flips the Range/Oven breaker. The water heater breaker does not flip to the center, but does not work. Flipping it off and back on makes it work again. The Range breaker does flip to the center and shuts off. When I go to inspect the panel the Range breaker feels warm, not scolding hot, but warm. The water heater breaker does not feel warm. Which is strange because the range has not been run for many hours at this point, but the water heater has. The water heater manual calls for 6 AWG and poled 60 amp breaker, "for maximum safety", it says. Previous owner installed 8 AWG and 50 amp breaker. But I don't see why this would also trip the Range? This seems to have started after I opened the panel recently. I popped in a poled 40 amp breaker, while the panel was live, to see if the breaker I purchased would fit. Could that have caused a problem? I also notice that when the water heater is running there is a slight inconsistent buzz, or crackling sort of noise, coming from the main panel.. only when the water heater is running. Having a hell of a time figuring out what is going on here. ThanksJA: What's the make and model of your oven? And can you guesstimate how old it is?Customer: GE, 2 yrs oldJA: Do you plan on doing the work yourself?Customer: yesJA: Anything else we should know to help you best?Customer: Think my lengthy first question about covers it

Need more help with my water heater tripping breaker. Ok,

Need more help with my water heater tripping breaker. Ok, replaced 3800w with 3000w elements. Still trips breaker. I checked all wire connections with a meter. All have continuity with each other. From thermostat to element and from top wires to the bottom wires. Are both elements trying to come on at the same time? Both temps are set at 120*. I've probably reset breaker at least 6-8 times. Can the breaker be faulty now?

I have a 50 gallon 4500 watts water heater right now and

I have a 50 gallon 4500 watts water heater right now and it's not sufficient for my house. I wanted to switch to a tankless unit but it looks like for a house my size (7bd, 4.5 ba), a 27Kw 150amp+ is needed. My house has two panels that I assume are 200 amp each. I can make room for the breakers, but since everything else in the house is electric and I have 2 sub panels for the pool and kitchen and RV, I'm concerned about overloading the panel. Am I able to put in a tankless unit for endless supply? Would I be able to put in a second tank instead?

Thank you for your past answers---as it is a big help for

Thank you for your past answers---as it is a big help for the homeowner to understand the electricians calculations. If you answer soon I might not get back to you for several hours, since I am going to our state capitol for something todayNow I've got questions on the service cable size. I see that typically for 200 amp residential services it's either 4/0 Aluminum or 2/0 copper.From the meter to the lower apt. circuit breaker panel I am looking at 45 ft.--and this would have to go through 3 90 degree bends. It looks like the 4/0 aluminum SER is really big, and that would be a real chore to pull that far. So the 2/0 copper cable is smaller (and a lot more expensive at $16/ft) but I guess I could afford it. To get to the upper apt. breaker panel is about 27 feet. (with about 22 feet on the exterior of the house).Questions:1. If the service cable has to go 45 feet from the meter to the breaker panel is it losing it's capacity to carry 200 amps? I have looked for a table to tell me how far this size can carry the 200 amps.. Would I end up having to pay for even bigger SER cable because of the distance.? I have also seen that Home Depot can get from Southwire 3/0 copper cable and it is not that high---$3 per foot. And it is supposed to be good for 225 amps. However, the Siemens Unipak meter bases have a 400 amp bus.2.Does the 2/0 copper service cable also just come in a bundle--- or come in separate strands, too? The Home Depot listing shows it in a bundle of 3 2/0 conductors and one #1. I saw that the aluminum has 3 4/0 conductors plus 1 2/0, but I was unable to see any 2/0 copper service cable in the store. The reason I am asking is I am under the impression that conductors lose some ampacity when they are in an insulation jacket, (i.e. you can't have romex in a conduit.) Between my meters and my breaker panels I think it can be run in 2 inch conduit----I hope they don't have to use 2 1/2---but I believe it would require a conduit body where it enters the house and the 2 1/2 inch ones are really big.3. After I come under the floor I only have 2x6 joist to run between. I am wondering if this cable can be run in that size of joist space exposed or if it has to be in a conduit? I have had different views on that. Then it has to go up into the wall cavity about four feet. So I guess this would be in flexible metal conduit? I've looked at the 2 inch and 2 1/2 inch 90 elbows and don't see how their big radiuses would work at this spot, although they would be used on the outside of the house.4. Regarding the Siemens meter bases, again it is a little confusing to me. They can have 225 amp tenant mainbreakers, but the bus is only 400 amps and the meter bases are 200 amps. Would I not be able to put in 225 amp circuit breaker panels---which it could take because I would have electric heat and perhaps an ondemand electric water heater in each unit. Plus for the lower apartment an electric dryer and a laundry circuit have to be added. So the amps demand is up pretty high. The other option I could consider is having the dryer on the lower apt. circuit, and having a stnandard or hybridwater heater serving both units but powered from the upper apartments panel. That splits up these two heavy loads. Up until now the water heater was on the lower unit panel, with a dryer and range and electric heat, going through the old service! I'm glad nothing burned up! I guess they rewired this in 1950, and by then it had been remodeled into two large apartments, but they just used 100 amp Federal Pacific panels! (They did have some additional fuse boxes for the range and water heater). Thankfully I switched some of the major stuff over to gas in 1992, and took a lot of the electrical load out.You can see what the Siemens UniPak metter base looks like on the Home Depot site. It looks like it should work----but why do they say it can have 225 amp tenant breakers and only 200 amp meter bases?http://www.homedepot.com/p/Siemens-Uni-PAK-2-Gang-225-Amp-Tenant-Main-Breaker-Meter-Socket-WP4212RJ/206109568?cm_mmc=Shopping%7cTHD%7cG%7c0%7cG-BASE-PLA-D27E-Electrical%7c&gclid=CKv_geeL79ACFYhgfgodQekIvw&gclsrc=aw.ds
