Final answer:
False. The 'Rim notch' mark is not the first mark on the front end of the bender head.
Step-by-step explanation:
The statement that 'The 'Rim notch' mark is the first mark on the front end of the bender head' is False.
In electrical engineering, a 'bender head' refers to a tool used for bending electrical conduit pipes. The 'Rim notch' mark is not the first mark on the front end of the bender head, but rather, it is a mark used to align the pipe within the tool.
On the front end of the bender head, there are typically several marks or measurements that indicate the desired angle or position for bending the conduit.
