TED highly recommends that a licensed electrician or installer do the installation of the MTU
and CT’s. Many jurisdictions require that a licensed electrician and/or contractor perform
the work. However most jurisdictions allow a homeowner to do electrical installations in
his/her own home. If allowed, and If you prefer to do the installation yourself, then you must
read and understand the entire procedure prior to starting.
1) Learn about Electrical wiring and installations:
a) Obtain and read a suitable guide to electric wiring, such as “Beginners Guide to
Electric Wiring” by F. Guillou & C. Grey, “The Complete Guide to Home Wiring” by
Black & Decker or any of the many other books on the subject. These are usually
available at your local library or through booksellers or online at Amazon, Barnes &
Noble, Books-a-Million, etc.
b) Obtain information from your local utility or government agency on safe procedures
and permitting requirements.
c) Obtain a copy of the latest adopted edition of the National Electrical Code or Cana-
dian Electrical Code for reference. These are usually available at your local library,
booksellers or online.
d) Seek help from a friend or neighbor who has successfully installed electric wiring
before.
2) Understand Electrical Services
a) Typical System Voltage for residential electrical services in North America is 120/240V
Single Phase 3 Wire 60 Hz. Some small businesses will use this voltage as well.
This is nominal voltage and will uctuate ± 10%. TED is designed to work on volt-
ages from 100/200V to 130/260V.
b) TED Model 1001 will not work on 120/208V Three Phase 4Wire or 120/240V Three
Phase 4 Wire services. TED Model 1001 will not work on any Three Phase Service
nor will it work on services where the nominal voltage is over 120/240V. TED will
work on 120/208V Single Phase services derived from 3-Phase systems. Other TED
Models may be available for this. Please refer to our website.
c) Typical service sizes are 60A (Amps), 100A, 150A, 200A, 300A & 400A The size
you have will depend on the size of the residence and large electrical loads such as
electric heat, air conditioning, water heaters, etc. TED Model 1001 is designed to
work on services up to 200A. Other TED models are available for larger services.
Please refer to our web site.
d) Fig A-1 (Page 28) shows a typical service arrangement.
3) Understand your Particular Installation Situation. There are numerous types of electrical
service installations. Determine the specics of your installation, before you start.
a) The service can be overhead or underground.
b) The main device can be a circuit breaker or a fused switch.
c) The panel can be circuit breaker type or fuses (though typically you will only nd
fuses in older installations.)
