I have a reliance 6 circuit transfer switch that was

I have a reliance 6 circuit transfer switch that was installed by a prof. electrician many years ago. I had a Coleman 4000 w generator with the 3 prong female output only. The electrician adapted a 3 prong male for generator/4 prong female to the feed to the transfer. I bought a new generator PowerMax 10,000 w that has a 4 prong female source. I hooked up the 4 prong to the reliance 4 prong. All plugs now match. I now only get power to circuits 1,2,3. Nothing to 4,5,6. My Prof. Electrician has been ill and could not check it out for the past 3 weeks. We have a blizzard on Cape Cod, MA right now. The furnace is one of the dead circuits. I have a suicide cord to backfeed that once circuit for furnace for an emergency (I want to live long and prosper so I do not want to use this work-around). Suggestions??? Thanx in advance.

I have a portable generator that connects to a transfer

Hello, I have a portable generator that connects to a transfer switch plug. The generators breaker trips when plugged into the transfer switch plug. Is this because the generator needs to be grounded to the exterior grounding rod?JA: I'll do all I can to help. How long have you been dealing with this?Customer: Since it was installed about a month ago. All the wiring from the transfer switch to the main panel is correct.JA: How old is the system in question? And have you consulted an electrician yet?Customer: The house is only 10 years old. I installed the transfer switch about a month ago.JA: Do you plan on doing the work yourself?Customer: Yes unless it requires serious work in the main service panel that is beyond my scope of ability. I am a General Contractor but not an electricianJA: Anything else we should know to help you best?Customer: I don't believe so

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 a Generac whole house natural gas back-up generator

I have a Generac whole house natural gas back-up generator installed at my house. When the power company's service is interrupted due to a storm, etc the generator kicks on automatically and takes over until power is restored. My question is as follows: Is the electrical power that my generator creates (and for which I am paying the gas company for the gas consumption it uses) also being run through my home's electric meter and billed to me on my next monthly electric bill? In other words , do I have to pay the electric utility for power to my home that they did not supply? If that is the case, is there a legal means to have my generator's power output bypass the home's electric meter? It doesn't seem fair that I should be double billed.

I have 11.5Kw PV panels connected to 10.22Kw of

I have 11.5Kw PV panels connected to 10.22Kw of micro-inverters feeding a 60A breaker in my 100A subpanel in my garage (grid tied). The subpanel is connected to a 100A breaker in my 200A main service panel in my house. The micro-inverters disconnect the PV panels when there is a power failure to avoid back-feeding the grid. Of course, since my solar array is connected to a subpanel, the micro-inverters are not looking at grid power directly but to my home's electrical system. I want to add a standby generator; for multiple reasons preferably located behind my garage. To avoid the micro-inverters from re-connecting the PV array when the generator re-energizes my home electrical system, the PV array must be isolated when on generator power.My first idea was that I need two Automatic Transfer Switches with one some 150 feet of wire away. Can I do this? Can one be the master ATS, the other the slave?My second idea - Generac has a 50A Smart Management Module (SMM) with a lockout switch that isolates the circuit to which it is wired. I still have the ATS some 150 feet away. Is there any reason I can't have the ATS so remote from the Genset? Alternatively; if I put the generator at the house; is there any reason the SMM cannot be so remote from the ATS?
