From a code perspective it's not allowable to have the neutral and ground connected in more than one location (temporary or not). From a practical standpoint it's a very low probility it would ever be the source of a problem.

Absolutely. The power from a MEP is high quality. If you see it on a scope you will see it is VERY clean. My UPS may click online for a second when the heatpump kicks on but that is from a short dip in voltage from the high current surge of the compressor.

The MEP-804 is 3 phase only. It can't be converted to single phase.

Not overloading a generator with an ATS is not a guideline. If you use an ATS you MUST have AUTOMATIC load shedding as to not create an overload on the generator. If you do and its a permitted job its a guaranteed fail from the inspector. If you have a MTS then it is assumed that the load...

Be sure to read up on the code for generators in your area. If you are using an ATS the rules are different concerning connected load. You aren't allowed to automatically attach more connected load than your generator can handle. If you have a 5kw genset then you can't put more than 5kw of...

Its common to install a defrost/emergency heat bypass relay for when you are on generator power. That relay will block the signal to the contactor coil that energizes the heat strips. My HP has 2 sets of heat strips. One set is used for emergency heat and one set is used for defrost. They are...

That's a really good question. When you are looking at a surge rating there are a couple of numbers to consider together. One is the Surge Current Per Phase. On that one the Square-D looks good at 80kA where the Eaton is a little lower at 50kA (the Ultra is rated at 50kA where the MAX is 45kA)...

I do most things to industrial standards. I don't apologize for it as much as I used to.

Well, Classic Medico Overkill being what it is I doubt you want to follow me down that rabbit hole! ;) Something like this is a decent practical unit: http://www.amazon.com/Square-Schneider-Electric-HEPD80-Electronics/dp/B00CONA1OQ/ref=pd_cp_23_2?ie=UTF8&refRID=0R6B4JXFBDRMWP0KTH7R BUT - If...

Thats the trick with lightning protection.. If you are directly stuck you are uh.. What rhymes with struck? Oh yea, Screwed.. The best you can do is to make it harder for it to get inside if you take a strike nearby. I have an arrester on my panel outside and I know it has saved my bacon more...

Since you already have a ground/neutral bonding point in your home system you would remove the bonding bus bar in the generator. You are now required to do a 4 wire hookup from the generator connecting both hots, the neutral, and the ground to the corresponding conductors on the house. Its OK...

The cord is 100'. That lets me keep the generator out of the yard and on the driveway. It also allows for more sound isolation from distance when we are using it in the field to power lights for small film productions. 100' is about the limit I would go on 6ga and still expect full power. If I...

Its about a 5" cube. Not that big. Here is a photo of it mounted on the house with the 50a plug/6ga cord connected.

I hear ya. That inlet box doesn't show the bottom but it does include the 50a receptacle. It is a complete assembly. On the Amazon page it comes across as just a very expensive plastic box but I assure you there is more in there. :)

Voltage drop is absolutely a killer to motor driven appliances. In general a 100' 20a RATED drop cord should be treated as a 15 amp cord for voltage drop. When I'm using my generator in the field for power I use a power distribution box like this one -...

In case you are interested this is the inlet that I used. It uses the "California" style twist-locks with the extra center pin. I like how these fit together better. http://www.amazon.com/gp/product/B009TNTZ8M?psc=1&redirect=true&ref_=oh_aui_search_detailpage This would be its matching...

My MEP003 is trailer mounted and serves double duty for field power and home backup power. I have a 50a outlet mounted on the generator frame. When I'm using it in the field I have a cord that plugs into a breakoutbox. When I'm using it for home backup the same cord connects it to the generator...

The reason why you go with a single point ground is to make sure that the ground conductors carry only fault current. If you bond the neutral and ground in multiple places you are creating parallel conductors that can carry neutral current and fault current. Current will follow all paths which...

I had a friend find out the hard way that his propane generator while convenient was costly to run. His 17kw unit sucked a 500gal dry in a week. The tank wasn't totally full at the beginning of the ice storm but wow. My little Honda EU1000 burns about 2 gal of gas a DAY running the fridge, a few...

You may want to check the NEC on grounding of generators. Your transfer switch doesn't switch the neutral and with that you don't bond the equipment ground at the generator end with the system ground. You should remove the ground rod wire at the generator end from the GND terminal and connect it...
