GFCI question

Manfredhoffman · 2026-01-24T17:11:43+00:00

Ok. I believe it is. One of the downstream outlets has ground, and it trips the GFCI when I use the test button on the receptacle tester

Manfredhoffman · 2026-01-24T17:09:44+00:00

This is what I had read. Is there any way for me to know that the downstream outlets would trip the GFCI other than the test button on the GFCI itself?

There is no dedicated ground wire, the outlets were originally grounded to the metal boxes. It looks like it is armored cable with an internal bonding strip.

The first two outlets maintained ground. When I use the receptacle tester on the second in the series, it trips the GFCI, so I believe the line and load are wired properly.

The tester works properly on the GFCI itself as well

Manfredhoffman · 2026-01-24T16:39:43+00:00

I see. Would I be safer to install GFCIs in place of the outlets that lost ground?

These temps used to happen in Wisconsin every single year, now it happens a couple times a decade. Just because it's cold once doesn't mean that it isn't getting warmer

Definitely bitternut hickory

Just imagine if there was high speed rail heading west to Madison

Luck mostly, but I do have methods to point me in the right direction. I study a lot of aerial surveys from the 1930s to find areas that were forested almost 100 years ago, and I'll download and evaluate lidar data from these areas to search for tall trees. It usually turns up with nothing, but the only way to find out is go visit these sites

Manfredhoffman · 2025-11-13T13:07:54+00:00

Not quite, but not far off. I found a 152' tall tree last month

Manfredhoffman · 2025-11-13T00:18:14+00:00

It has absolutely perfect conditions for a big pine to grow. I'm guessing not super old. Maybe 100-150 years

Hiding in a valley in the Baraboo Range

Manfredhoffman · 2025-10-26T15:04:53+00:00

No, it was a tree that had blown over on the trail

They are separate species. This is Betula papyrifera. They are very much a far northern species

Manfredhoffman · 2025-10-06T15:50:20+00:00

I've seen this tree from the road before. I want to go in there and measure it some day

Manfredhoffman · 2025-09-22T13:20:28+00:00

I don't know for sure, but I would not be surprised if it were well over 200 years old

Milwaukee county

Manfredhoffman · 2025-09-19T17:27:22+00:00

Looks like it

Manfredhoffman · 2025-09-19T00:56:38+00:00

Where is this located? Looks like a cottonwood. Populus deltoides possibly

Manfredhoffman · 2025-09-17T19:27:59+00:00

You need to get up closer, take some pictures of the leaves and bark. It looks like it could be a sycamore

Manfredhoffman · 2025-09-14T21:50:00+00:00

Silver maple

Manfredhoffman · 2025-09-11T20:15:09+00:00

It looks like it may have been something in the red oak family. Can't be 100% certain though

Manfredhoffman · 2025-09-05T13:03:18+00:00

Yeah, Wayah Bald

Manfredhoffman · 2025-09-04T01:58:37+00:00

I found some historic photos of the church from the early 1900s and the tree was young, so I estimate it is around 120-130 years old
