We are upgrading a 200 single service to a 600 amp main into

We are upgrading a 200 single service to a 600 amp main into 4 200 amp services (none of the services will actually draw more than 150 amps and three of them will draw less than 125 amps we may tie two of the services together?). We are not in a position at this time to invest in any generation equipment at this time as the upgrade is running 20K. All of these services will be in a newly built building, what can we do to make the installation of a generator into each of these 4 services? We are thinking that we'd be best off to have a different generator for each service as they will at time not have any need for back up power, what do you think? I see on line that a transfer switch for each one of the services (220 volt 200 amp.) would be close to $500.00, just don't have the $2k extra right now, can we put in a junction box that could be tied into, and would that make it easier?Thinking of running four generators at one time, how much propane volume and pressure would we need to be supplied to this building?

I have just purchased a back up Briggs and Stratton petrol

HiI have just purchased a back up Briggs and Stratton petrol generator.The generator has 2x 240 volt/15 amp AC plug outlets (single phase I understand) and one 12volt DC plug.The maximum power is 3600 watts and continuous power is 3000 watts.The generator is earthed to the built in frame. It is pushed around like a wheelbarrow on 2 back wheels.I plan to use the generator to power my Grundfos waterpump and medium size domestic refrigerator when the mains power is down.The water pump runs on 240volts and 800watts (surge 1500 watts)I am not sure about the fridge but it is a newish power saving model.Questions:1.Do I need 2 powercords: one for each device?2. What thickness(mm2) and amp rated powercord do I need?3.What is the maximum safe length of the above powercord that I can use?4.Can a back up generator be used in rain under a gazebo with open sides to ensure ventilation?How risky is it to use a portable generator in the rain.

I have a food trailer. It is wired 120v. I have a 33amp Onan

I have a food trailer. It is wired 120v. I have a 33amp Onan 4Kw generator to run it. I have a 12v 450cca battery to run the generator, and water pump. The generator powers lights 3 48 inch fluorescent fixtures, small ref/freezer (1 amp), steam table (10 amps) and the AC unit (15 amp). I have it connected to a 20watt 3amp Solar panel to charge. I am having a problem with the battery charge lasting long enough for our hours of operation. We run it approximately 11 hours per day, Thursday, Friday and Saturday. The voltage starts to drop on Saturday afternoon and then the the generator shuts down. I am reviewing options to keep the battery charged. What are some good options.

I purchased a second hand dryer off of Craigslist and it had

I purchased a second hand dryer off of Craigslist and it had the 3 prong plug. When I go home my dryer outlet is the 4 prong outlet. So I removed the 3 prong plug (which had 3 screws for 3 leads for attaching) and am preparing to buy the 4 prong plug to replace and I see that there are 4 lines. I thought they were interchangeable but now I am confused. Can I put a 4 prong plug on a dryer where I just see three screws for attaching? Thanks, Andy
