Heat Damage to High Power Appliances

WP_20140413_001

We’ve covered loose terminals in replacement electric shower isolators, but here is a loose link inside an electric hob. The installer has tightened the live terminal correctly upon installation but the metal links between the second and third terminal are loose which can just be made out below the red terminal blocks in the picture. This has caused arcing and heat to damage the third terminal eventually resulting in it’s demise. Remember, if you are planning on installing high power appliances yourself, please make sure all of the terminals are tight – if in doubt, consult an electrician.
