Automated Heavy Duty Load Transfer Assembly 120-277 Volt, 40 Amp 1475

$ 179.99

<<NEW>>Transfer heavy electrical loads using virtually any home automation technology.  

Want to add a 240 volt electric-car home charging station, but don't have the capacity to add another circuit to your circuit breaker panel?  This device can save you thousands by allowing you to share an existing circuit with another appliance like an existing electric oven or range.   Home automation technology allows remote transfer during charging periods using your cell phone or set up predetermined schedules for automated transfer.   Allows you to add intermittently used, heavy electrical load like electric vehicle charging stations, heaters, spas, shop equipment like welders, compressors, and much, much more without extensive and costly rewiring.

Can be used to transfer between two heavy loads using a single electrical circuit source (up to 40 Amps), or transfer one heavy electrical load between two electrical sources (e.g. commercial power grid and solar). No need to change your existing automation system or use multiple technologies.  We can custom assemble the correct unit to meet your exact needs.  Contact us with any questions, special needs or 277 volt models.

Heavy duty load transfer switches are simply not available for most automation technologies.  Our Model 1475 Automated Load Transfer Switches allow A/B switching between two heavy loads using virtually any other home automation technology you choose.

Our custom assemblies adapt a standard automated wall switch of your choice (included) into a super A/B switch capable of transferring almost any residential and most commercial loads.  This design also allows tremendous flexibility for modifications.  Models available for use with popular voice control systems like Amazon Alexa, Google Assistant and Siri.

All models come standard with two 3/4" PVC conduit adapters.  Contact us if you would like a different size, location, or quantity of adapters.  The adapters can also be deleted in favor of a rear opening for installation over a recessed wall outlet box.  A weather resistant switch cover can be added for outdoor installations.

Note:  All ampere ratings are for inductive loads.  Pure resistive load ratings are 10 amps higher (i.e. 40 amp rating = 50 amp resistive load).  Contact us if you have questions.
