Telephone signal is more prone to EMI (Electro Magnetic Interference) effects of Electrical energy flowing through the power cable. To avoid such EMI effects, telephone cable is laid little bit away (300 mm at least) from the power cable.
Your question should read, 'How much clearance is needed between LINES.... (not 'phases')?' The answer will depend on local authority regulations. The clearances in air tolerated by REC companies in the UK is 90 mm line to line and 127mm phase to earth. Even though there is a greater potential difference between line to line, the gap is less. I think it's to do with public safety if it flashes to earth.
No. It needs room to move. At least a two inch clearance is preferable.
Make sure they are locked to up prevent theft.
The clearance for a 440-volt line to earth at a road crossing typically depends on local regulations and safety standards. Generally, overhead power lines should maintain a minimum clearance of about 5.2 meters (17 feet) above roadways to ensure safety for vehicles and pedestrians. It's essential to consult local electrical codes and utility company guidelines for specific requirements in your area. Proper signage and warning systems should also be in place to alert motorists of the power lines.
YesYou should be careful with power cables nearby and make sure they are shieldedwww.peaksensors.co.uk
.002
I believe the clearance should be within .002 and .007 thousands of an inch. and also the end play clearance, should be between .002 and .007. you should check the bearing caps with plastic gauge, and the end play wiyh a feeler gauge.
clearance between door and floor with forced air system
300mm
The exhaust valves should have .005 inches of clearance, and the intake valves should have .004 inches of clearance.
The minimum clearance between a crane superstructure and a fixed object should typically be at least 3 feet to allow for safe operation and prevent any collisions. However, this clearance distance can vary based on the specific crane model and manufacturer guidelines. It is essential to consult the crane's operation manual and follow regulatory requirements when determining the minimum clearance needed.

The loud hum that you hear is probably a 60 Hz. hum. It is caused by induction from an adjacent power feeder. When electrical feeders lay parallel to each other, the electrical magnetic field caused by the current flowing in the power conductor induces a field in the other parallel telephone cable set. These types of cables should not be run together but run with separation of at least 50 mm between them. The proper installation when distance separation of the cables from one another can not be physically obtained is to cross the power cable and the telephone cable at a 90 degree angle until the separation can be obtained.
No, it is not safe to plug both a telephone and an electricity cable into the same socket. Mixing different types of cables can lead to electrical hazards, short circuits, or damage to the devices connected. It is important to use sockets for their intended purposes to prevent any accidents or damage.
On a Yamaha 1980 XS400 the valve clearance for the inlet valve should be 0.0003 inches. The valve clearance for the exhaust should be 0.006 inches.
