Electrical boxes house devices, splices and fixture connections. This range covers Arlington's box lineup: concrete floor box cans, recessed TVBU television boxes, fan and fixture boxes for flat and sloped ceilings, non-metallic screw-mount device boxes and the recessed In-Box family. Size by cubic-inch volume first, because box fill limits how many conductors you can land: a shallow sconce box holds about 5 cu. in. against 22.5 cu. in. for a single-gang screw-mount box. Then match the mounting. Flanged boxes suit stucco and siding, steel pan and I-joist brackets carry fan weight, and exterior boxes need a weatherproof cover. Maple Electric Supply is an authorized Arlington dealer.
**How do I know if a box has enough volume for my conductors?**
Add up the box fill. Each conductor, device yoke and set of clamps takes a share of the cubic-inch capacity. Arlington marks volume on the box, so a 22.5 cu. in. single-gang screw-mount box gives more room than the 5 cu. in. shallow sconce box. Calculate to the Canadian Electrical Code before you pick a size.
**What is the difference between a non-metallic and a steel Arlington box?**
Non-metallic boxes do not need bonding to the box itself and resist corrosion, which suits exterior walls, stucco and damp areas. Steel boxes such as the pan fan boxes and the I-joist brackets carry mechanical load, so they are the choice where a fan or a heavy fixture hangs off the box.
**Can I mount a ceiling fan on any box in this category?**
No. Only boxes built and marked for fan support should carry a fan. In this range the steel ceiling fan boxes, the cathedral boxes for slopes up to 45 degrees and the adjustable I-joist brackets are the fan-rated options. A standard device or sconce box is for devices and light fixtures only.
**Do the recessed In-Box units work outdoors?**
The weatherproof In-Box models with extra duty covers, including the stucco and siding versions such as DBVM1CGC, are built for exterior walls and keep a plug protected while in use. The Indoor In-Box and its combo covers are interior products. Read the model description before ordering for an outside wall.
