Word play, I still don't agree, bad word play at that, IMO.
It doesn't say Measure the Voltage and granted it doesn't say Add them either, is my point. Well Between the two, what is that...
You won't give me the fact that the Code does not say to measure the voltage. A two Point operation on Three points of power, do they make that meter?
Or neither will you give me, to Add the voltage between the two devices, well between the two there isn't 300 bolts, if that's the case... back to #4 post
There's two devices and the code says "between", well 1 Device (insert some math sign((except infinity-THE math symbol)) and another 1 Device.
Whats' the between math symbol? Another later thread sure assume ADD, no I'm not assuming anything.
The the highest voltage between the devices in the OP would be 208.
I'll assume that's a two point measure with a meter, to stay with your train of thought.
404.8(B)
...so that the voltage between adjacent devices does not exceed 300 volts.
there is 208 in one Receptacle
and 110 in the other.
If you don't agree then why does MH show 308 volts Between ? He gets to measure the voltage to a summary?
Whoops it is an ADD function ~ But You won't give me that in my explanation, it doesn't say add, nor measure it says between.
One pole isn't getting metered in the 208 receptacle (staying with MH illustration against my rational) and is just dropped because not it's between, well we can't go there cause the MH-I the metered pin is on the far side, not between.
I'm not going to get into the 3 phase verses a single phase "adding" the sum for a sum number(MH Illustration), nor proof those numbers for it, here.
