## What are the minimum clearance?

The minimum clearance meanwhile is the difference between the lower bound of the orifice diameter and the upper bound of the shaft diameter. The maximum clearance in a loose or sliding fit is always greater than zero; on the other hand, in a tight fit both the maximum and minimum clearance are negative.

## What is electric clearance?

The electrical clearance is the electrical isolation between two conductive components, whereas the creepage indicates the conduction of electricity across the surface of a nonconductive component. The clearance and creepage distance are two important parameters while designing an electrical assembly.

## What is the desired minimum clearance for power cable to communication cable?

Clearance above ground of the lowest conductor As per IE Rule 77

Low and Medium Voltage 5.8 Meter
Low/Medium /HT line up to 11KV If Insulated Conductor 4.0 Meter
Above 11 KV Line 5.2 Meter
Above 33KV Line 5.8 Meter + Add 0.3 meter for every additional 33KV

## Can you install an electrical panel in a closet?

The short, safest and most efficient answer to this question is yes. According to the national code, with relation to electrical panels in closets: NEC 240.24D Overcurrent devices shall not be located in the vicinity of easily ignitable materials, such as a clothes closet.

## Do electrical panels need covers?

Panels on the exterior of a home needs to have a cover. Damaged covers or panels without a cover may allow rain and snow to enter the panel and this could become dangerous, as well as a loss of power may occur.

## How close to power lines can you build a house?

When measuring the clearance distance it is important that you only measure it at ground level. If you are planning to build or renovate any structure located closer than 15 feet horizontally from an overhead power line. If any portion of your structure or building will be located underneath a power line.

## What is the safe distance from 11kV power lines?

As per the Indian Electricity Act, buildings should maintain a horizontal distance of 1.2 metres from 11kV lines and 4 metres from 66kV lines.

## What does negative clearance mean?
