These are the incidents resulting  from a disruption in the "transport" of electricity in electrical machines, transformers, electrical or electronic devices and electrical conduits If these are damaged by fire, these damages are covered by the fire warranty. But if these devices are damaged following a surge without fire, such as appliances burned by the effects of current disturbance, These damage is covered by the warranty called "Damage to Electrical Appliances".

Notice on the difference between Machine Breakage Damage and Electrical Damage in Electrical Equipment
In several commercialized contracts, the exclusions from the electrical damage Warranty stipulates that the electronic components when the damage remains limited to a single interchangeable assembly are formally excluded from the guarantee.
This exclusion is introduced to decide on a case of strong nuance which is the case of the internal or external origin of the damage to the electronic modules. Intra-original claims of internal causes are covered by the Electronic Damage Warranty (or Machine Breakage), while the original claims of external causes related with the conditions of electric power  supply are covered by the Electrical Damage Warranty.
