|Intellitec Automatic Energy Select Switch (AESS)|
Cat. No. MT-00-00714-000
Intellitec's Automatic Energy Select Switch (AESS) is designed to
be used in RVs to share the power available from a single circuit
breaker between two large loads. The AESS applies power to both
appliances until the primary load is turned on. It then removes power
from the secondary load to prevent the circuit breaker from being
overloaded. This function is particularly useful for sharing power
between the microwave oven and another "sheddable" or postpone-able
appliance, such as the washer/dryer, or water heater. Typically, this
function has performed with selector switches, forcing the owner to
manually switch between the two appliances.
The selecting function is particularly useful when the microwave oven
is the principal load. Power is always available to it, assuring that
the customer can use the microwave whenever required and it's internal
clock remains operating. While the microwave is in use, the function of
the secondary load is postponed until the microwave is finished.
• Allows two 20 Amp loads to operate from a single 20Ampbreaker
• Automatically switches between the two loads as the demand requires
• MeetsNECsection 551-42(c) for adding breakers over the maximum limit
of five and allowing for more than two, thermostatically controlled
• Minimizes circuit breaker tripping.
• Eliminates manual appliance select switches.
The underlying principle of the AESS is that certain appliances used in
an RV, such as the microwave oven, hair dryer, or toaster need to
always be available, when the owner wants to use them. These are "on
demand" appliances. The use of others, such as the washer/dryer, water
heater, or air conditioner can be delayed to a slightly later time with
little inconvenience to the owner. These are postpone-able loads.
Postponing the use of these appliances leaves enough power to operate
the "on demand" appliances.
Power is supplied to the AESS from a single circuit breaker. An "on
demand" load is connected as the primary load and a "shed-able" load is
connected as the secondary load. When power is applied to the RV, it is
supplied to both loads. When the primary load is turned off and at
least 30 seconds has passed, power to the secondary load will be
