Review on Intermatic IG2240 IMSK Intermatic Smart Guard IG2240 IMSK Whole Surge Protector by Bob Ramthun

Well made with one exception. The pigtail installed by the manufacturer was not connected according to the NEC code. It has been miswired by the manufacturer to supply power to the bottom of the switch used to disconnect (see attached drawing). The NEC specifies that vertically mounted circuit breakers should supply line voltage to the top lugs and load current to the bottom lugs. After fixing this, I installed it at my mom's house after losing 3 circuit boards in the dishwasher due to power surges. No boards have been lost since installation, but only time will tell how well it performs. By the way, I am a state-certified master electrician with over 25 years of experience. Please do not attempt to repair the wiring unless you are a qualified and preferably licensed electrician or electrical engineer. The manufacturer must repair the wiring on all future products.
