A customized table skirt and two carrying bags for the tables are included with this item. We'll contact you to determine your skirt preferences.

This high voltage demonstration model shows a variety of contact hazards with overhead and underground service. The model consists of one or two wooden tables with folding legs and various components which are placed on the table(s). All other components (building, transformers, vehicles, figures, power lines, etc.) are stored in plastic containers.

The Agricultural scene version contains the street scene table (4’ model) plus a second table with a substation and an agricultural field. The house contains the model's power supply. Lights mounted on the front and back indicate that the model is energized. A foot switch on the power cord controls power to the unit.

Models are easily transportable. Tables measure 2 x 4 feet. One or two plastic tubs hold all other components. Models can be set up in less than 10 minutes.

Models are powered by a transformer which produces a 10,000 volt, 28 miliamp current. The current is much lower outside the house at contact points. This produces dramatic arcs when contacts are made. Crimped connections on internal wiring insure good bonds. Wiring to the poles, padmount transformer and excavation site are easily connected by jacks.

The following electrical contact hazards can be demonstrated with the 4 foot model:

• Contacting overhead lines with an antenna,
• Contacting overhead lines with a kite,
• Contacting overhead lines with a metal pipe,
• Contacting buried lines,
• Contacting overhead lines with tree limbs,
• Contact with a padmount transformer,
• Energizing a vehicle with a fallen overhead line,
• Energizing a metal fence with a fallen overhead line, and
• Contacting a house service drop with a metal ladder (exploding pole transformer).

About the components:

Safety is important. Each model is wired with a foot switch so the demonstrator can control current to the model. A spring-loaded hot stick makes it easy to handle components from a safe distance. The circuit is protected by a 3 amp fuse. In addition, demonstrators should wear tested linesman’s gloves (not included.)

Each kit includes:
• Demonstration board(s),
• Hot stick,
• Three grounded human figures,
• Model house containing power supply,
• Tree with figures,
• Metal ladder with figure,
• Three strand transmission lines,
• Padmount transformer,
• Metal fence,
• Table skirt,
• Die cast metal SUV or school bus (whichever is available when your order is placed),
• Backhoe,
• Instruction manual.

Demonstration components which come with the Agricultural Option Table are:

• Substation with gravel base, transformer and metal fence,
• Grounded fire truck,
• Farm tractor and grain auger, and
• Double-pole, high-tension line.
• A pivot irrigation system can be ordered separately.

The instruction manual contains directions for setting up the model. In addition it contains helpful information on presentation skills and three separate scripts for demonstrating hazards to lower and upper elementary grades, first responders and construction workers.
