Final answer:
The claim that a stub or 90° bend is made using the Star mark on a bender head is False. The Star mark is often used for back-to-back bends or offsets, while an arrow or 'hook' mark typically indicates the start of a 90° stub bend.
Step-by-step explanation:
The statement suggesting that the stub or 90˚ bend is made using the Star mark on the bender head is False. When making a 90˚ bend, or stub, in conduit bending, a different mark on the bender head is typically used to align where the bend will start. For example, on a hand bender, an arrow or a 'hook' mark may indicate where the stub will start for a 90˚ bend, rather than a star mark. The star mark on many bender heads is often used for back-to-back bends or offset bends, not for the stub bend. It is important for anyone working in electrical installations to follow the correct procedural steps and utilise the appropriate marks on a conduit bender to ensure accurate and safe bends.
