Most of elect guys can help.. no need for 3 phase.. my thinking is don’t install anything that you can’t get at a campground. To make it simple the 240 will have basically two hot legs (120 Volt ea) going to your power pannel and a common. (often refered to as a ground) Common wire color is normal White—A safety earth ground is seperate from gen set and box =Green.Not really complicated but maybe something better explained one on one. I will see if I can find a referance diagram to explain.. Does your gen set have built in circuit breakers? if so how are they marked? Make of gen set would help also. Bob

Yep, I will not need the 3 phase at all. Should not affect connecting at a campground. Will check on the breaker! Its a Sullair 15 kw with an air cooled diesel engine. I’m thinking the generator its self will regulate the voltage at the 240 volt outlet. Will get back with you on the breaker size. I’m using a 200 amp main panel (which is changeable to 100 amps if needed) to wire to because it’s free, new and has breakers for my house electrical.

You will want 120/240 split phase, if that’s an option. This is what you get at a campground. This has 240V between two hot leads (L1, Red wire and L2, Black wire). Measuring voltage between either hot lead (L1 or L2) and neutral, white wire, you will read 120V.

The regulator should be integral to the generator.

I assume you will be using a transfer switch. If not, I suggest you reconsider as it transfers voltage and neutral between commercial and generator power.

I’m guessing you need to do a really good shop building the sound enclosure. An air cooled engine should be a lot louder than a water cooled engine.

Mikie T,

Is this a new store bought generator? If not, you might go online to the manufacturer’s site for information. Wife won’t let me near electrical projects anymore. Something about relocating a wall light switch hot, when the hot hit the BX flexible metal sheath, sparks flew. Oh yeah, I was holding the hot cable between my knees – not too good!

Generators
normally have a voltage regulator; therefore, no regulator is required is
require between the generator output circuit breaker and the main AC
panel.

There
should be four main wires between the generator and the main AC panel. These wires are:

• Two phase wires, (also called
  ‘Hot” wires, 240VAC between them, 120VAC to Neutral).
• One Neutral wire, (should be at
  least the same size wire as the two phase or “Hot” wires).
• One Ground wire, (runs from the
  frame ground terminal on the generator to the ground bus inside the main
  AC panel).

There
should also be ground wire from the bus frame to the ground bus in the main AC
panel. Many people confuse ground and
neutral wires. The purpose of the
neutral wire, (usually white in color), is to provide a return path for 120VAC
current to the generator. The purpose
of the ground wire is to ensure that an electrically conductive surface, like
the frame or aluminum skin of the bus, does not become a current carrying
conductor when the insulation of a wire fails.

In the AC
world inside a bus or RV, ground wires only conduct when an energized
conductor/wire shorts to conductive metal.
When properly wired, this fault, (short circuit/ground fault), will
cause the appropriate circuit breaker to trip.

Improper grounding and/or mixing Neutral wires and ground wires can
cause an electrocution hazard.

To keep it simple for first time. Wire your gen set to a outlet just like the 50 amp at a camp ground. Available almost any where. Wire your camp ground cord to your electrical box.. when your in a camp ground/home=plug into their power..unplug and plug into box attached to gen set(with breakers on gen set off) start gen set. turn breakers on= power to coach via gen set. extra work but simple!!!! no transferr switch involved or worry about neutral ground bonding etc… If you want more complicated–we can do it! or you can ad those features later. Remember here most of these guys start out with transferr switches and inverters etc.. Basic they are doing the same thing but much more complicated.. remember to shut breakers off before transferring any plug ins then turn back on. Bob

Keep it simple stupid. is what that stands for… that is what I was trying to explain. If you do it the more complicated way there is more to go wrong if you don’t understand it.. I tend to lean heavy on KISS..Have you already bought Gen set?? That’s pretty big; even though I seem to remember you saying something about some big HVAC units? 15,000watts divided by 120 volts = well over 100amp service.. your going to find some campgrounds with as little as 30amp 120volt only. The high end conversions are running big gen sets ; I really don’t know why?? Ck and see how big of wire it takes to handle 50 amps at 120 volts per leg..Just food for planning… Then check the wire size of a 50 amp rv cord . All kind of choices of lifestyles and where one wants to spend their bucks.. Bob

Air Cooled??? I assume you have made provisions for both intake and cooling air? Might have to have some pretty big holes in the bays for that…..
