To confirm that you have 90-degreerated supply wire, look at the cable television jacket or wire insulation. If you have plastic sheathed cable (typically referred to as Romex), search for the letters NM-B or UF-B printed on the plastic sheath.
If you're still unsure, either call an electrician or select a component that isn't identified with a supply wire temperature level requirement. Inspect the Electrical Box for Capability and Strength, Heavy Fixtures Need Strong Boxes, If you choose a heavy light component (the one we purchased weighed in at a significant 25 pounds.), examine your electrical box to ensure it will support the weight.
from any electrical box that is threaded to accept No. 8-32 machine screws for attaching the crossbar (see "Mounting with Screws and Cap Nuts" and "Mounting with a Threaded Pipeline" in Additional Info below).

Multiply this figure by 2 for 14-gauge wire and 2. 25 for 12-gauge wire to get the minimum box volume in cubic inches. Plastic boxes have the volume stamped within.
All ceiling-mounted components, from pendant lights to chandeliers, are set up similarly.

Strip about a half-inch off of the component wires and about a half-inch off of the supply wires. Some tasks are much better delegated the pros, Secure free, no-commitment quotes from licensed electricians near you.
