Electrical Power tools

WHAT IS MAINS POWER/TOOLS.

Mains electricity is the general-purpose alternating-current electric power supply. In New Zealand, the Mains voltage is 230V. Which is an a.c. (Alternate Current) This means that the current is constantly changing direction. Mains powered tools are the tools that can only be used Mains power

THREE MAINS POWER TOOLS I HAVE USED.

Welder

Drill

Grinder

TASKS I HAVE USED THESE TOOLS FOR.

Welder- Connecting two different pieces of metal material together for various projects (eg toolmakers clamp)

Drill- Making a various range of holes in different diameters (measured in mm). (eg weather vane drilling holes for the rivets to go into)

Grinder- I have used this tool when manufacturing my toolmakers clamp to grind down my weld to look clean and sit flush with the rest of the surfaces .

WHAT IS “RCD”

Why is it important?

RCD stands for Residual Current Device. It is a device that is designed to prevent any fatal electric shocks if you touch anything that might be live. An RCD will most likely be used in the workplace, or at home. RCD eclectic cables have a switch in them that help minimise the risk of getting any harm from electrical hazards.

WHAT IS DOUBLE INSULATION?

Appliances and tools of this type are called "double insulated". They have two levels of insulating materials between the electrical parts of the appliance and any parts on the outside that you touch. ... Double insulation construction of appliances and tools allows the manufacturer to produce a lower-cost product. Double insulating also helps make a heavier duty cord so they cannot be damaged as easily as other cables.

EXTENSION CORDS.

Why are extension cords a safety hazard? 

If the extension cord is covered, heat is unable to be realised and could combust resulting in a fire. You should always make sure extension cords are visible and if at all possible, not running across highly trafficked areas. They can be a potenetial trip hazard for people walking through the area.

PPE.

No matter what you're doing you should always wear appropriate PPE to protect you from any hazards presented by power tools, such as Dust and Debris. PPE such as goggles, dust masks, gloves, hard hats, and safety boots should be worn where appropriate.
