Distinciones Clave

Penetrating floor finishvsSurface-coating floor finish

A penetrating finish absorbs into wood fibers and wears only as the wood wears without chipping, while a surface coating sits on top of the wood and can chip or scratch.

Standard chop sawvsBlade-sliding compound miter saw

The standard chop saw has a faster cutting action suited to quick, repetitive cuts on small molding stock, while the blade-sliding compound miter saw is slower but more versatile.

Overhead costsvsDirect costs

Overhead costs (e.g., bookkeeping and legal expenses) are not tied to a specific job, while direct costs (e.g., rental equipment, labor, fasteners, glue, sandpaper) are charged directly to a particular job.

Assembling picture-frame casing on a flat work surfacevsAssembling picture-frame casing directly around the window

The correct method is to assemble the mitered frame with spline biscuits and glue on a flat work surface, then lift the completed frame to the window; assembling around the window is incorrect.

Handsaw with shopmade jig (delicate moldings)vsPower miter saw (general molding cuts)

Delicate molding profiles prone to splintering should be cut with a handsaw guided by a shopmade jig with pre-cut miter slots, whereas a power miter saw is used for standard milling cuts.

Shielded or lead-covered conductor bending radiusvsNonshielded conductor bending radius

Shielded or lead-covered conductors rated over 1000 V must have a minimum bending radius of 12 times the overall diameter, while nonshielded conductors require only 8 times the overall diameter.

NEC 305.5
Load-bearing steel wall rough openingvsNonload-bearing steel wall rough opening

In a nonload-bearing steel partition, the rough opening for a door allows 1½ inches extra on each side for wood studs at hinges and strike plates; panelized (load-bearing) openings add 12 inches of width to accommodate two trimmer jack studs and a wood stud on each side.

Carpentry and Building Construction, Section 29.3, Rough Openings (Nonload-Bearing Walls)
Differential levelingvsSingle-setup leveling

MV-90 cablevsMV-105 cable

Type MV-90 medium voltage cable has a maximum operating temperature of 90°C, while Type MV-105 has a maximum operating temperature of 105°C; both are suitable for dry or wet locations.

NEC Table 315.10(A)
Window/door schedulevsRoom-finish schedule

A window/door schedule is a chart providing rough-opening sizes for windows and doors, while a room-finish schedule identifies the materials and finishes for floors, walls, and ceilings in each room.
