Voltage Drop Calculator

Thin Pipe

• Calculator - [1]
• Wire Source: - https://www.radiofence.com/heavy-duty-pet-fence-boundary-wire-1-000-feet
• 4% loss at 240V, for 1000 feet, 14 ga
• Say 1000 feet of wire - 14 - $180 for 2 strands.
• 240v to 24v charger - $80 [2],
• 240VAC
• 2amp gets 480watts to the end point
• Use doggie wire -
• PV - 3000W array - say 2000W average over 6 hours. Or 24 hour average of 500W.
• Storage in 12 motorcycle batteries - is about 1200Whrs.
• About 400W from the charger assuming charging loss. For 18 hours (outside of day) - 7200 Watt hours. 6x more than the batteries store.
• 700 watts microwave - 3 minutes - 1.5 watts over the day
• circulator pump - 60W
• blower - only during day
• $40 smart charger - 5A - [3].

Fat Pipe

• 1/0 triple wire is $1.33/foot - [4]
• 4/0 triple - ? Platte-Clay Electric - [5] - $1.43/foot - 3% - 40A

• 2/0 triple -
• 1/0, 1/0, #2 triple - 86 cents - 20 A at 1000 feet rating by the book 3% drop. Available next week.

Examples

• 235 volts at the end of a 4/0 pipe on 50A.

• With another 1000 feet on a 1/0 pipe, voltage goes down to 225.
• With another 1000 feet on a 4/0 pipe, voltage goes down to 230.

• Typically, appliances are designed for 10% voltage tolerance. [6]

Transfer Switch

• 60A 240V transfer switch - [7]. 4x13.5x11.5 inch dimensions.
