Been on the Internet since before there was an Internet. Remember UUCP, news feeds, and Gopher?

You need to supprt at least the weight of that beam hanging off the underside of the rafters, it has considerable weight. the shims will do it.

comment Using a 30-amp tandem circuit breaker for a 120/240v circuit?
Neutral is neutral, even if the 240 legs are taken off alternate breakers. Wow, I see what you mean on that setup now, I couldn't see from the picture that the breaker pair is only fed by one leg. I didn't quite get the description and it sounded like adjacent breakers were being used to produce 240V. Using alternate breakers to produce 240V is damn dangerous if you need to be sure the power is cut and make the wrong assumption.

Do you live where it snows abundantly? Looks like auxiliary weight support for an extended roof overhang so the rafters don't take the brunt of the load. Tapered shim wedges can be used to take up the slack.

comment Why does my outdoor tap have a diameter of 1-1/4“ inches, not the standard 1”?
Remains of an ancient Vacuum Breaker? Threads are quite short and there appears to be a step or o-ring groove that a seal gasket would fit in. @Ecnerwal suggestion to cut just short of threads is a fairly standard removal method, a little heat with care to not damage internal seals will help.

comment Are “1/4 turn” water supply valves more reliable than “multi-turn” valves? Or vice-versa?
Plus you have problems with the stem packing leaking, another annoyance.

@Tester101 - Yep, I'm pretty sure it was a less than adequate ground pigtail coming off the fan. Small size, extra heat = burnt insulation.

On his particular breaker, it's a non-separatable tandem so this pin won't work. I've dealt with these for paired slim breakers on other brands, insert the barrel and install both breakers at once.

comment Using a 30-amp tandem circuit breaker for a 120/240v circuit?
You wouldn't be getting 240V if they were both on the same bus Leg, 240V is created by the additive combination of +120V from L1 and -120V from L2. If you were to pull the breakers out, you probably find this is one of those designs where the power bus tabs alternate so adjacent breakers are on separate legs. In a dryer, the motor and controls are run from one leg at 120V between the leg and Neutral and the heating element takes the full 240V between L1 and L2. And, yes, I've seen an appropriate sized nail run through the holes in the handle to pair the breakers for 240V use.

Umm... Don't like the sounds of that. Would help to post a picture so we know what exactly is burnt. NM/UF type cable typically has a bare copper ground wire, not a green insulated wire. This is US power, correct?

Pictures or it didn't happen (grin). Need to see what's being described.

comment Electrical wire a 240v sprinkler lake pump
I could say something witty about the obviousness of the use for something labelled Ground Screw, but yeah, make a hook on the end of the bare ground wire that should be in your cable and make sure the hook wraps in the direction the screw tightens. Playing with 240V with a profound lack of knowledge can be the last thing you do before entering the Pearly Gates...

comment Can I repair this crack in my sprinkler backflow preventer?
Glad to hear, often the permanent fix ends up being the least expensive in the long run. Now be sure to drain everything for winterization, the crack probably was from a winter freeze.
