Clumping bamboo in MA will not be the same as clumping bamboo in FL :-) Even in my pretty mild climate, clumping bamboo is an extremely manageable plant and I see no reason not assume a similar well-behaved habit in colder zones. From a regional bamboo specialty nursery: Overview of Clumping Bamboo Clumping bamboo are defined as having a non-invasive rhizome structure (known as pachymorph rhizome) which differs from the better known �and sometimes feared�running bamboo (leptomorph rhizome). Clumpers form a tight cluster of gently arching culms extending from a relatively small root mass. Each underground bud pushes upward forming culms, and do not become long running rhizomes. Instead, clumping bamboos grow outward in a circular formation at a modest pace of 2 to 12 inches per year. Canopy growth is also relatively slow, usually gaining a couple feet of height and width annually. Height range at maturity is between 10 and 20 feet for most species. There are some exceptions; tropical and subtropical species can reach 50 feet or more in the US, given hot, southern climates. We have a special affection for hardy clumping bamboos. We believe these plants will help overcome popular fears about bamboo, and pave the way to its acceptance as a significant addition to the landscape as well as its incorporation into our culture. Bamboo Garden is on the forefront of introducing new and exciting species of clumping bamboo into the United States and promoting their multitude of uses. Though many are new to cultivation, clumping bamboo are gaining recognition for their landscape value as low maintenance alternatives to the larger, more vigorous, running bamboos. Fargesia sp. �Rufa�, with plumes of feather-like foliage, provide a wonderful accent to the small urban garden. Larger species, such as F. robusta, create dense evergreen privacy screens to over 15 feet. The gracefully weeping culms of Borinda angustissima and F. sp. �Jiuzhaigou� support masses of tiny leaves with a delicate, airy texture. Outer culms can be topped to make the plant more compact and upright. New introduction, F. sp. �Scabrida�, has outstanding colors: purple culms outlined by rusty-red culm sheaths contrasting with dark green leaves. Some species, such as F. nitida, are among the most cold hardy bamboo, surviving temperatures as low as negative 20� Fahrenheit. Most thrive in a partial shade environment, but there is enough variety to find a suitable clumping bamboo for just about any need. Our selection have special significance and unique qualities for the home garden or commercial landscape. We hope the pages of our website offer a new perspective of the possibilities and wonderful variety among clumping bamboo. Here is a link that might be useful: Bamboo Gardens

I don't know if it's permissible (and I don't think it looks as nice) but when wiring lv alarm wiring, we often cut off unused wires flush with the outer insulation. You will also see alarm, telephone and other lv wires with spares wrapped back around up the outer insulation. In 120/240 land, I'm sure capping is preferred. If one of the other conductors fails in the future, the 'spare' wire can be brought into service provided it's re-coloured at the ends to depict what it's doing, ie, red or black.

Shouldn't someone installing a 4500 watt coffee machine, in what is obviously not a residential setting, already know this?? Anyone qualified to do this would would not have to come to a homeowner DIY message board to find out how to do their job.

A wire runs directly through a CONDUIT that is sized for whatever wires run through it. A SLEEVE is an open-ended, much larger pipe installed under a "structure" so that later a new conduit or wire can be installed below the "structure," without cutting or tearing it up and having to repair it. Sleeves are most typically installed under walks so that later an irrigation pipe or lighting wire can be run through it ... without disturbing the walk. Lots of times walks or drives are installed before irrigation contractors begin their work. Usually, sleeves and conduits now days are plastic. But they can be whatever the work calls for. Sleeves only need to keep a cave-in from happening, so they could be made of something "laying around" as long as it is large enough diameter and strong enough to do the job.
