Use Main Breaker or Backfeed on Subpanel?

Re: Use Main Breaker or Backfeed on Subpanel?

For me, the problem is that in order for the customer to "like me" I communicate a concept: It's as easy to get what they want the first time, as it is for me to fudge in what I expect to install.

When I hear "Can you wire these lights to operate this particular way..." or something along those lines, I say, "Anything is possible, within the confines of the code."

"We can do anything you'd like."
"Can do."
"No problem."
"Of course."
"Would you prefer this, or that?"

This attitude changes when it comes to the trim, and they ask, "Can these lights be made to come on with these others" or something like that, when it's too late. They asked for a configuration at the rough, and are changing their mind. When we jump backflips at the rough "for free or close to it", then we walk away from the rough feeling as though it's perfect.

At the rough, my flexibility based on their whimsy was essentially free, as long as the wire hadn't actually been pulled yet. Now, there is no going back without a serious charge, and that catches some off-guard. And what was perfect is now flawed. It's easy for us to believe that the customer feels that we screwed up: now you can't bend to whimsy. You can't work the miracles you subliminally engrained in them you could work at rough time.

When the job is small, the events are large in scale; an extra stands out like a sore thumb and is easily explained.

When the job is a large home with countless details and decisions and many of them verbal, many of them undocumented, it becomes exponentially difficult to track and charge them, much less explain them all away.

On a home I am currently working on, I'm probably a couple days overdue. My boss will expect a list of changes to justify it. When it comes down to lack of scheduling, schedule compressing to get inspections before the house is complete, lighting issues (with the customer's lighting company - whom we also deal with, so their mistakes look like we're both at fault for their mistakes)....

...breath...

...appliances the customer might have known about the entire time, but never informed us about, cabinets where no normal human would have cabinets...

...the list becomes so oppressive and so intermixed as to liability and time involved and whatnot, how do we proceed?

Do you say, "I blew it," or "It was just a bad house," to the boss and forget the paperwork?

Do you say "Stick it to them," and bill for every conversation, every little item that sucked an hour from the house you'll never retrieve? How do you bill for the added time in tripping over materials all over the place while you were trying to work?

As it is, I'll be writing and pondering a remembering every little detail, trying to attach a time to it, and find that when I present the customer with the list I need to present to my boss, I will get shot, cursed, and hated.

That's my rant.

Respect your electrician, he's probably got an ulcer on your account. :)

I agree about the cheese factor, only because it would be misleading to future buyers of the house. If they toured the garage and opened the panel cover, I expect most would come to the conclusion that the breaker in the garage was the size of the feeder. In this case, not much difference, but if were a 20 amp feeder and a 100 amp CB, it would be a rude awakening for the buyer.

That said, I would still do the "cheesy" if the HO wanted it and it met code (as it does in this case).

For Bob, I cannot recall seeing a breaker that was not 60/75.

BINGO! it is what the customer wants.

IMO It would only be cheesy if this was not the customers request.

That said we each have to do what we are comfortable with. :)

Re: Use Main Breaker or Backfeed on Subpanel?

Thanks for the replies! Interesting discussion that I'm learning from here.

In this particular customer/electrician situation, I am paying T&M, except for certain things my electrician has established a fixed cost for, which are few. The detached garage project is all T&M.

As far as schedule goes, he can come over and work whenever he can or wants to. There's been several weeks worth of work to do. When I had to get power to the new furnace (and the nights were getting cold), I did ask that he come over as scheduled. Generally speaking, I just try to keep things moving along, but if he can't make it over or I'm not ready for wiring, it's no big deal. I'm paying his standard hourly rate plus material costs, and he is an independent electrician (not contractor), with no employees.

For this subpanel breaker issue, I'm more concerned about the hardware store's retired electrician giving me bum advice. When shopping for the new, larger subpanel, I had picked out a Siemens convertible box, the kind without the main breaker.

After I explained the situation with the protected feed from the main panel, trying to be helpful, he said, "Why Mickey Mouse around with a backfeed breaker, just get this other model with the 100A main already installed for $10 more?"

As far as someone assuming that a 100A main breaker on the subpanel means the detached garage has 100A available, I would put a label next to it that says "Caution: This subpanel is serviced by 80A feed from main panel located in residence garage. Maximum load 80A only!" or something to that effect.

But at the end of the day, I could see where two 80A breakers are at least redundant in protecting the feeder wires more so than one 80A followed by the 100A "disconnect" in the sub.

I'll place a call to the inspector, and see what his preference is, if any.

The detached shop/garage is kind of a pet project to me. I'm using all commercial or industrial grade receptacles, switches, lighting, etc, as I cannot stand the crap that is typically used (and I've replaced) in my former (tract) homes. The GFCI's are all hospital grade, as I wanted the LED indicating outlet power, and did not want nuisance trips, for example. Detail oriented, yes, anal, whatever, I've heard it already. But I do take pride in my home and always notice and compliment "a job well done" by many (definitely not all) of the tradespeople I've employed.

Is the inspector footing the bill? :p you are paying for it, that's how it should be done.
End of story. :cool:
