many expensive household appliances do come equipped with surge protection and line conditioners, especially those that are more sensitive to voltage fluctuations or power surges. However, not all appliances include these features for several reasons:
Cost considerations: Adding surge protection and line conditioners to appliances can increase their production costs. Manufacturers might choose to omit these features to keep the price of their appliances more competitive and appealing to a broader range of consumers.
Appliance type: Some appliances, like basic kitchen appliances (e.g., toasters, blenders, coffee makers), may not require surge protection or line conditioners as they are relatively less sensitive to voltage fluctuations. For these types of appliances, manufacturers may prioritize cost savings over including additional features that are not essential.
Independent surge protection: In some cases, consumers might already have surge protectors installed in their homes. Therefore, manufacturers might assume that users will take care of surge protection at the outlet level rather than incorporating it into individual appliances.
Design and engineering constraints: Inclusion of surge protection and line conditioners can add complexity to the internal circuitry and design of appliances. Some appliances may not have enough space or appropriate components to accommodate these features.
Local regulations and standards: In certain regions or countries, there might be specific safety standards or regulations that govern surge protection for household appliances. Manufacturers might follow the guidelines accordingly, which can vary from one region to another.
It's worth noting that while some expensive household appliances may not come with built-in surge protection or line conditioners, consumers can still purchase external surge protectors to safeguard their devices from power surges and voltage fluctuations. These surge protectors can be plugged into the wall outlets and used to connect multiple appliances simultaneously. This way, users can add an additional layer of protection for their valuable electronic devices.
