But maybe the primary *is* broken on your dead end street. Or there are
several breaks in the line and the only thing still connected to your
house is the transformer. You don't know what the state of the
distribution lines are, so you can't rely on them to stall the generator
if you forget to open the mains. So you need another failsafe.
You are also failing to follow the long standard engineering practice
of having a system setup such that it requires a minimum of two failures
for a life threatening fault. You are advocating that homeowners with
generators intentionally provide the first failure. So now that lineman
is only one ripped glove away from being electrocuted. You may be
book smart, but you sure are stupid.
The second failsafe procedure is the utility workers training which
tells them to treat everything as live, always use their protective
gear, ground lines they are working on as applicable, etc.
If you want "two failures for a life threatening fault", then redesign
the entire electrical distribution infrastructure so that every
transformer is isolating and every line segment is floating, no grounds
anywhere. That way any single fault will not in itself cause a life
threatening fault. One fault would only reference the voltage on that
segment to ground or whatever and not cause a dangerous situation
without a second fault to provide another contact point at a different
I'm sure that a linesman whose been putting in 16 hour days for a week
reconnecting lines after a hurricane will appreciate the attitude about
Secondly, who said it's only linesmen? Last I heard, homeowners don't
have such training, and a 4KV+ line lying in the ground isn't biased
as to who it bites. Including unwary homeowners.

It\'s not just anyone who gets a Starship Cruiser class named after them.
Regardless. If my installation allowed my wife/adult-son to energize a line
from the home generator because I didn't bother installing a positive
disconnect, and it killed an over-worked, tired lineman who missed one step
in his safety procedures, the guy is still dead. Or some stranger touched a
down line at an accident scene, that was supposedly switched off by the
utility but wasn't actually de-energized yet because of my generator, they
are still dead.
And regardless of lawyers, wrongful death suits, contributing factors, or
any other 'paper excuse', someone ending up dead because I skimped on a
safety feature, isn't going to help me sleep at night.
Some of us care more for our fellow man than to just say, "Well, they
obviously didn't follow procedures", or "Another candidate for a Darwin
award." Maybe you should go tell the widow of a dead lineman who was
working for 20 hours trying to get people their power back, how it's
obviously her spouse's fault that he's dead. Or the widow of the rescue
squad guy that touched a live wire after the utility folks pulled all the
fuses, trying to save someone else's life that they deserve the "Darwin
Award" for the year.
I'm single, the switch gear is under control of a single competent
The main breaker *is* a positive disconnect. It is not mechanically or
electrically interlocked with the other breaker however.
Well, I'm not as concerned with avoiding enabling other people to injure
themselves. Every time you drive your car you are also enabling other
people to injure themselves and are relying on them to follow procedures
such as crosswalks and traffic lights to prevent them from being injured
by your car.
If you have sleep issues they have medication for that.
Life is full of risks and as they say "They knew the job was dangerous
when they took it". While I'd not be quite so blunt with that widow(er),
the bottom line is that the person in question knew they were taking a
risk by working excessive hours or short cutting procedures and the
ultimate responsibility for the results of that risk land on their
shoulders. I enable them to kill themselves every day by simply funding
the power utility.
According to the OSHA rules of Ontario. Massive mistakes were made and
management would be held responsible and probably jailed for lying about the
state of the lines in each case.
The generator hookup people would have their pee-pees slapped but no where near
the foreman and the upper people for the deaths.
Now one was in Peurto Rico and there are so many more waiting for jobs that one
isn't gonna' be noticed.
Wire a tranfer switch box in with 4 or 6 circuits you want to be backed up and a
proper plug on the damn thing.
Don't play with people's safety or your own. Your unit coming becoming energized
may not be fun either unless you have money to burn.
The meter base does not isolate the neutral. Unless you have a fault in your
home it won't be a problem.
I backfeed my paned through a breaker. The backfeed breaker is adjacent to
the main breaker. I created a sliding mechanism that makes it impossible
to turn on both breakers at the same time. Works, prevents accidental
feedback. No messing around with feedback cable. Easy as 1-2-3:
1. Switch main breaker off
2. Mechanism drops out of the way of backfeed breaker
3. Turn on backfeed breaker.
1. Turn off backfeed breaker
2. Lift and hold mechanism while
3. Turning on main breaker.
It all depends on the inspector. If it is effective why would they
care. There is a lot of lesser junk out there with a NRTL sticker.
Bear in mind U/L listed the old style aluminum wire, FP breakers, SqD
AFCIs. and virtually every recalled appliance that bursts into flames
or electrocutes the user.
