Mep016d voltage. Please help

[dstang97]

On 120v only I'm getting 60v each on L1+L2. This is putting a meter on the ground stud and terminals. I'm not great with electrical but I'm thinking this is wrong.

Was it raining or just finish raining when you started it? The voltage regulators are real sensitive in my experiences and after they dry, voltage returns to normal.

 

[dstang97]

No all the time it's 60vs L1+2

Measure from Neutral to L-1.

Measure from Neutral to L-1.

I'm guessing L2 is the neutral. L1+L2=120v

That is odd. I run mine in the 240 single phase mode to give me 2 120 volt legs just like my house.
120v 1ph L1=60v L2=60v (L1 to N, L2 to N)
240v 1ph L1=120v L2=120v (L1 to N, L2 to N)
What is your power volt readings at the courtesy outlets?

Where is the neutral on these generators? 120v only

 

[jamawieb]

LO is neutral. You should get 120 from L0 to L1. If the reconnection switch is positioned correctly.

 

[dstang97]

I will make a diagram with all my voltages later on today.

 

[Gunzy]

L0 is neutral. When in 120v 1ph you will get;
L1-L0=60v
L2-L0=60v
L3-L0=0v

In 240v 1ph you will get:
L1-L0=120v
L2-L0=120v
L3-L0=0v

At least that is what I get from mine.

 

[dstang97]

I only want to talk about 120v configuration
Is the neutral and ground tied together? If so I'm getting correct voltage.

 

[Guyfang]

Have you ever seen this set run correctly? Or have you just acquired it, and can not get it to run properly?

 

[Gunzy]

Neutral and ground are not "Tied." What are your voltages at the courtesy outlets?
Again, in 120V 1ph:
L1-L0=60v
L2-L0=60v
L3-L0=0v
L1-L2=120V

If you plan on connecting this to your house when your power is out it will need to be set to 240V 1Ph to power your house.

L1-L2=120V

This is exactly what I came up with today. Does my wiring look right?

Here is a drawing. Generator is not tapped to a neutral in 120v mode which I find as odd but it's the way I understand it. It's for 16b

I would have never guessed you would get 60vac from each leg to get 120vac. Learn something new everyday

That's why I thought something was wrong because you don't get 60v in commercial power.

It caused me to go do some digging. Had never seen this delta configuration before. Still researching. I am no expert by any stretch of the imagination. Just now got in to these gen sets and trying to absorb as much information as possible. This site IS the place to do it.

 

[dstang97]

I absolutly hate these gensets. Mep-016x's

 

[Dwnorton1]

See that's exactly why I love this site. Now I am going to be leary of those units without having to live the pain myself.
