I meant to follow up last week’s beginner’s guides to industrial machines (pt.1 and pt.2) with a mention of getting electrical service to the machines. If you just have a machine or two, the space is relatively small in that you can locate machines close to outlets, this isn’t much of a problem. However, if you have a larger open room, electrical service delivery becomes a bit trickier. For this example I’ll use my shop.
Even though my space is small as these things go (less than 3,000 sq ft.), I don’t have the option of locating machines next to outlets. In the short term one can use extension cords but that can get you into trouble with the authorities if yours is a commercial venture. Even if it’s just you, electrical cords are unsightly and unsafe.
You have two basic options; both involve drop down electrical service from overhead. You may not have known that but most of the electrical service in a sewing facility comes from overhead. It makes things much neater and safer. Mr. Fashion-Incubator installed pedestals. From the circuit overhead, he installed junction boxes and then electrical outlets closer to the point of delivery (larger image). We also used the outlets to wire in the overhead lighting for those machines. This type of service is good if you are settled and won’t need to shift machines around. Oh and if you’re wondering, the brown fabric are covers for the machines and thread stands (again thanks to Stu who sent me the fabric!). It is so dusty in the southwest, I need to do that. You should probably do it too.
If you need more flexibility, the better option is to install what I would loosely describe as overhead power strips. This product goes by a variety of names: feeder rail, Feedrail®, raceway, bus rail, busway, overhead trolley, trolley rail, trolley feed rail, trolley busway etc. At right is a photo I took of feedrail at Patternworks in LA.
Feedrail® (a registered trademark owned by Universal Sewing) is pretty neat; it’s sort of like railroad tracks but inverted and suspended. You need a special jack or plug that rides on the rail so it can travel freely up and down the track with just a slight tug. The photo of the rail at Patternworks shows a box at the bottom which is what a machine plugs into. This kind of power set up is mandatory for cutting tables, you really don’t have any other options. The power supplied to a knife can travel up and down the table.
Feedrail track comes in 10 foot lengths and are easily joined together. You can buy it used fairly easily with those synonyms above. The best option if you have it, is to lease space that already has feedrail installed. It is usually listed as an amenity, particularly for spaces that had been set up as light industrial commercial sewing. I’ve left links below to the previous entries on commercial space in the event you need information like that.
