I just recently installed a whole house suppressor at my distribution panel.
I noticed that the original electrician bonded the ground to the neutral in the
distribution panel so all neutrals and grounds are on the same bars.
When I used to do this type of work a long time ago we used separate ground kits
in the distribution panel and bonded in the meter can; so ground rod-meter can-distribution.
Realistically it is the same thing just not as clean having both together in the panel.
If I remember correctly bonding the ground to the neutral is an NEC requirement to facilitate
ground faults and trip breakers faster, but not sure.
On the suppressor I had A and B lines, Neutral and ground. I can't help but think something is not right
about this terminating both the neutral and ground to the same bar.
If there was no distinction from the vendor point of view why have two separate conductors?
Is it that the suppressor is assuming a non bonded ground?
How could that be the case assuming NEC requirements?
Is there a risk here terminating the neutral and ground at the same point? (which is basically following the tenet of the existing bonding)
Thanks!
@WinnR,
Winn in spite of a lifetime in the electronics field I judge you're probably 'way ahead of me in house wiring. But am I right in interpreting your q as asking whether some installers don't distinguish between earth gnd and pwr neut ?
If so I'm apalled. Eng, Man, Fil, help ! ?
@dalehileman,
Thanks, I went back and read up on bonding fundamentals and it looks like my wiring is correct because my service disconnect resides in my distribution panel, not an outside main. So really the suppressor separate ground and neutral conductor is no different than any other device that has both. The bonding makes this a bit illogical though at first glance.
Stumble It!
