When calculating the electrical load draw on a panel there are 2 methods of calculation depending on the model of simpleSwitch.
For the model 240, the higher of the two electrical loads is to be used for the load calculation.
For model 240CT, the device is typically not required to be counted towards the load calculation.
Check with local electrical authorities prior to purchasing product on jurisdictional code for calculating loads.

• It is very important that installer sets the car charger device PRIOR to plugging charger into the car (as damage to simpleSwitch^TM may result if car charger device is not properly set).
• Electric Vehicle Supply Equipment (EVSE) (or home chargers) have settings that must be configured on the EVSE (not the car) prior to charging with simpleSwitch.
• The reason is that some vehicles remember the last charge and will try to draw the maximum charge possible. We want to limit the current running through the simpleSwitch to under 50 Amps. This is achieved by setting the charge rate on the EVSE.
• Simply stated, EV chargers must be set to a maximum of 48 Amps charging.

When using the simpleSwitch 240 model, there may be a need to set a delay to match the power surge current duration.

Electrical device with a surge current (e.g. Air Conditioner, other electrical devices with a surge current, typically containing a motor).

• If the simpleSwitch 240 Secondary (does not apply to the Priority) is connected to a device with a motor that will have a surge current,

set the time delay according to the duration of the surge current (typically several seconds).

• The suggestion is to start at a 4-second delay (position 2). In the event that the simpleSwitch 240^TM switches off the Secondary during the start of the AC motor (Power Surge) then set the delay to 8-seconds (position 3). In the event that simpleSwitch 240^TM still switches off the Secondary device during the start of the AC motor (Power Surge) then the device being connected to the simpleSwitch 240^TM may not be suitable for the simpleSwitch 240^TM.  Please contact technical support at (206) 494-3260 Ex 701.
• Set the dip switches according to the table below to set the time delay:
