Thank you for choosing the Splitvolt™ Splitter Switch™! Charging your electric
vehicle (EV) just got easier!
The Splitter Switch allows you to share your existing 240V dryer circuit

home charging, but avoiding the high cost and complexity of having an
electrician install a new, dedicated 240V charging circuit.
The Splitter Switch switches full power between your EV charger and clothes
dryer—automatically provides power for EV charging any time the dryer is not
running.
This new category of product can save you thousands of dollars and weeks of
time. Just plug it in, and Splitvolt monitors, displays, and switches full
24-amp power on-demand between

providing the fastest possible safe charging on a standard 30-amp circuit, at
a fraction of the cost of installing a new, dedicated circuit in your home.
Please read this manual before use.

Disclaimers
This product is intended for indoor use and must be protected from moisture
and the elements to maintain safety, durability, and preserve warranty
coverage.
This model is not safety certified. If safety certification is important to
you, please visit our store and select one of our safety certified Splitter

Note that power is prioritized to your dryer, so some special low-power dryer
features (such as wrinkle guard) may interfere with the operation of either
your Tesla EV charger or your SPS unit, and therefore is not supported or
recommended. Contact www.splitvolt.com/help
with any questions or for more information.
This product is designed to operate at a maximum continuous electric vehicle
charging rate of 24 amps on a standard household 30-amp circuit. According to
the National Electrical Code (NEC), exceeding this rate is unsafe. It can trip
the Splitter Switch internal safety circuit breaker, cutting off power, in
order to reduce risk of damage or risk of fire. Contact an electrician if you
ever have questions about local safety codes, or if you are unsure of the
condition of your wiring.
DO NOT DISASSEMBLE. OBSERVE ALL WARNING LABELS. Do not remove warning labels.
Connect to a properly rated, protected, correctly sized power circuit which
has been installed to local safety code standards.
If an electrical supply line, connectors, or other circuit elements are worn
or damaged, do not use and consult a qualified electrician. The Splitvolt
Splitter Switch is intended only for use with electrical circuits and wiring
that is in good condition and meets local building safety codes.
Set your EV charger or EV to a maximum charge rate of 24 amps for EV chargers
using NEMA 14-50 connectors.
This product is not intended for use with NEMA or other plug adapters.

Troubleshooting
The following table identifies steps for troubleshooting the operation of the
device. If you
are experiencing difficulty, please review the table below, check our website
(www.splitvolt.com), and then contact us at
www.splitvolt.com/help if you are still
unable to
resolve or have additional questions.
| Issue | Resolution |
|---|---|
| Splitter Switch’s LED and LCD are not turning on | Is power available? |
1. Check that the wall socket has power
2. Check that the wall plug is plugged in fully
3. Check that the built-in breaker is in ON position
The wall socket seems to be upside down| There is no universal orientation for
NEMA plugs, so yours could be upside down. Just plug it in anyway.
The pins on the cable do not match my wall socket| It is possible that the
wrong model was ordered. Please contact
www.splitvolt.com/help for assistance.
Not getting power from either
one of the sockets
| Double-check all plugs are pushed in completely. Note that the “EV”
socket will not have power when the “Dryer” socket is active.
Splitter switch is not turning off the EV Socket when dryer is running| 1. Turn Off/On the internal circuit breaker switch and verify whether this corrected the issue.
2. Check your house power panel for a partially tripped circuit breaker by turning On/Off the appropriate breaker, verify.
3. Confirm what type of dryer you have. If you have a gas line running into the dryer, you have a gas dryer (even if it is plugged into a NEMA 10-30 or NEMA 14-30 plug).
4. Turn off energy saver mode on your dryer. Does the splitter switch turn off the EV socket? If so, you have a rare
high-efficiency dryer that downshifts to 120V during part of the cycle.
Please contact www.splitvolt.com/help immediately for assistance.

Hear a buzzing sound coming from splitter switch| Turn off the breaker and
turn it back on. The contacts may have become misaligned. Powering on/off will
help it self-realign.
My Tesla has an alert saying “Unable to AC charge – Unplug and retry”| Simply
unplug/replug-in the charger handle to the vehicle to continue charging. NOTE:
Some special high-efficiency sensor dryer settings may cause multiple
switching, triggering the Tesla charger power protection fault to pause
charging. It is recommended that Tesla users do not use special low-power
dryer settings when charging.
My internal safety breaker keeps tripping off| Verify that your EV or EV
charger is only charging at 24 amps. If it is not, set it to charge at only 24
amps or less. If you are unable to change this setting, or/and the internal
breaker keeps tripping, please contact us at
www.splitvolt.com/help.
