Electricians read drawings and work orders, plan how circuits and equipment will be installed, and run wiring through walls, ceilings, and other spaces. They install switches, outlets, lighting, panels, and other electrical components, then test systems to check that they work properly and safely. They also inspect, maintain, and repair electrical systems in homes, commercial buildings, and some industrial settings. In many jobs, they troubleshoot problems, replace worn parts, and help upgrade older systems. Depending on the workplace, they may work on new construction, renovations, maintenance calls, or specialized systems such as alarms, controls, heating, ventilation, and energy-efficient equipment. They may also need to travel between job sites and work with other trades.

Carpenter
Carpenters read plans and measurements, then cut, shape, and assemble wood and other building materials. They build and install foundations, frames, floors, walls, roofs, doors, windows, stairs, cabinets, and trim. They also repair damaged structures, do renovation work, and finish surfaces so the final result is strong and safe. On some jobs, carpenters set up scaffolding, use power tools, and work with hand tools, levels, and measuring equipment. They may work on residential, commercial, institutional, or industrial projects, depending on the employer. Good carpentry also means checking accuracy, following building codes and safety rules, and adjusting work when plans change on site.

Aircraft Mechanic and Inspector
Aircraft mechanics and inspectors inspect aircraft parts and systems, diagnose problems, and repair or replace damaged components. They work on engines, landing gear, flight controls, hydraulics, and other systems needed for safe operation. They may read maintenance manuals, follow technical procedures, test completed work, and record repairs and inspections. Some tasks involve checking aircraft before and after flights, finding defects, and confirming that work meets safety rules. In some settings, they also help certify that an aircraft is airworthy when allowed by their role and employer requirements. The work can include both regular maintenance and urgent repairs to keep aircraft available and safe.
