No, when the electric oven you bought is in use, the power consumption is relatively large, and your household appliances can't be installed, which leads to wire burning. If the power is too high to burn out the line, you must bear the responsibility yourself. Another situation is the quality problem of the product itself, that is, product liability. The principle of imputation of product liability varies from person to person, with the producer assuming strict liability and the seller assuming presumed fault liability (a kind of fault liability).
