motors. To force these inadequate services to deliver power that is greater than their designed 15-ampere
capability leads to early equipment failure and potential fire danger. This must always be considered when
choosing the electrical supply.
• Burr King provides 1-½ horsepower, 120-volt machines with a 20-ampere power cables and
connectors. This is necessary to assure that the power cord does not dissipate excess energy (delivers all
available current to the motor), and to assure that the user plugs into a supply capable of delivering the
required 20 amperes of current. You can identify the 20-ampere cable by its 20-ampere plug that has a
90-degree orientation of the two flat blades. If a user defeats this performance and safety feature he
does so at his own hazard.
• At the application site you and our customer must assure 20-ampere service is used. Should the user
defeat the 20 ampere polarized plug provided by Burr King in favor of a 15-ampere service he may
experience nuisance circuit breaker trips.
• A 120 -volt, single phase 1-½ horsepower machine must always be connected to at least a 20-
ampere 120-volt source that incorporates 12-gauge wire at minimum. 20-ampere circuit breakers
must never be used with smaller than 12-gauge wire. Failure to observe this warning may create a
fire hazard and result in the loss of life and or property.
• It is common (by code and fact) to have five or more AC outlets wired to a single 20-ampere circuit box
breaker. This means that when a 20-ampere demanding device (1-½ horsepower motor) is connected to
one of the outlets no other device should be connected to the other shared outlets, in other words all of
the available current must be reserved for the 1-½ horsepower motor.
• 220-volt, single-phase 1-½ horsepower configurations should be connected to 15-ampere service.
Burr King machines are provided with appropriate power cables and connectors for this service
arrangement. Similar concerns exist for 220-volt, single-phase systems; however, 120-volt systems
are far and away of more concern and therefore require greater awareness and pro action.
• For 1-½ horsepower, 120-volt, single phase motor applications the use of extension cords should be
avoided. If it is necessary for an extension cord to be used assure that the cord does not exceed twenty
feet in length and is constructed with 12-gauge or larger wire. Failure to observe this will lead to
reduced performance, premature failure, and a potential fire hazard.
Remember that this is an important issue that effects product performance, reliability, and physical
safety. If you have doubts or need assistance call the factory. The new configuration machines will safely
deliver solid performance for many years provided they are supplied with and adequate AC power.
Finally, we think that you will agree the new configuration variable speed machines are a superior value
because of their improved reliability, improved tolerance to overloads, and extended capability!
