Re: Al Hildenbrand - Minneapolis - obituary Bill Addiss 15 hours ago

Thanks for the info. Sorry for your loss (and ours).

ElectricAL was one of our 'Old Timers', a Member since 2001. He helped make things interesting and informative around here.

To Al, cheers

You’re right, HotLine. I got sloppy and di- dn’t look closer at the pic. (I get any more senile I’ll have to try politics!)

Re: Estimating available capacity based on peak demand bigpapa 01/27/23 07:19 AM
The code now allows this. You have to provide at least 12 months of peak demand data from the utility bills.

Thanks Greg, I found more discussion on it here although from 2018: in which Don contributed, hopefully he will stop by with his thoughts on the 2020 and future code wording.

" These have the inline fuses which have special fuse blocks that limit exposure to the live parts. The fuse pops out when you access the fuse through a door in the fuse block. "

Sounds like what I referred to as "finger safe", a term I got from a friend that worked for Bussmann back then.

Re: AFDD's coming to the UK Texas_Ranger 01/18/23 12:22 AM
I've read rather convincing arguments that blanket 30 mA RCD protection in domestic installations would catch most arc faults because even inline arcs and L-N faults quickly lead to insulation breakdown.

Re: Circuit Breaker Lube renosteinke 01/14/23 11:40 PM
Reminds me of the “light bulb grease” sold at auto part stores. Or, even, the “ dielectric grease” sold there.

It’s been my experience that dielectric grease, despite the name, does nothing to prevent conduction by direct contact. It will bliss corrosion and prevent arcing through gaps (such as between a coil wire boot and a distributor hub).

Re: GFCI Failures HotLine1 01/11/23 08:51 PM
Doing inspections, I've had GFI devices that were 'faulty'. A few that would not reset, a few that would not trip on test, one or two that 'smoked' when tripped.

We won't mention the mis-wired ones, or the AFCI devices installed instead of GFI devices (OOOPS)

Re: More than one wire per lug? HotLine1 01/11/23 06:04 PM
It may be a 'hold your nose' thing, but when I had tools, I would not do it. (Period)

I have not seen anyone do this.

As an inspector, based on what the label stated, I have to take it. However, I would call Siemens and question that label.

Re: Seal offs with pvc conduit renosteinke 01/05/23 10:41 PM
For sealing against bugs, condensation, and the like duct seal putty or expanding foam are fine.

For explosion proof wiring you’re limited to listed materials — and that rules out PVC.
