3 phase branck circuits must have seperate neutrals??

[LarryFine]

I'm working with a gentleman that's been an electrician much longer than I have, and he said today that it's no longer allowed to share a neutral for a 3 phase branch circuit.

Ask him whether the same thing applies to an entire service, and why not.

MWBC's have their place, but for those two reasons and others that I have had lengthy debates here about, I do not allow MWBC's to be used when supplying my audio and video equipment racks.

No basis for this, just a personal fear.

And the little ball of white light at the CB when you reset it will tell you too....


No kids - do not try that.... Meter first - not reset untill clear.

Er, Bob, I think you might want to look into getting a new meter, you got a phantom voltage of 212 VAC in free air. Not good.:grin:

I don't have that model and can't quite make it out - but it might say "HOLD" under that... That button can be tricky....

That is exactly what it says.

Twas, an attempt at humor.

You in S.F proper, I grew up in the Sunset.

It doesn't have to be in the center position to tell if it's off.
