Wires and cables (conductors) are insulated and protected by a variety of materials (insulators) each one having its own particular properties. The type of material used will be determined by the designer who will take into account the environment in which a control panel or installation is expected to operate as well as the application of individual wires within the panel.

When the current is switched on or off, the electro-magnetic field increases and decreases, rapidly causing, in effect, a radio signal. The effect is similar to the crackle that can sometimes be heard on the radio or television when something like a fridge switches on and off. This radiated signal can be picked up by the other wires in the system and cause interference to the normal working voltages in the system

A highly disturbing device (variable speed drive, frequency converter, etc.) will have less radiation in the panel if it is “encapsulated” in a small, electromagnetically sealed, unpainted metal enclosure.

Ensure that identification tags and cable markers are legible, marked with a permanent ink and suitable for the environment where the panel is to be used. They should also correspond with those shown in the machine drawings and instruction or service documentation.
By Blandine Honorine. Electrical Wiring. Published at Saturday, January 20th 2018, 01:41:31 AM. Conductors and cables should run from terminal to terminal without any intervening joins. This refers to making a joint in the middle of a wire or cable. If it is necessary for any reason then use a suitable connector or terminal block. Don’t use a twisted and soldered joint.

You're permitted to use wiring channels if they're made of a flame-retardant insulating material. If you're working with back-connected control panels, you must provide access doors or swing out panels that swing about a vertical axis. Multiple-device control panels must have terminal blocks or attachment plugs and receptacles to terminate and connect all outgoing control conductors.
By Claudie Ulysse. Electrical Wiring. Published at Friday, January 19th 2018, 20:08:48 PM. Electrical equipment uses a wide variety of wire and cable types and it is up to us to be able to correctly identify and use the wires which have been specified. The wrong wire types will cause operational problems and could render the unit unsafe.
By Blandine Honorine. Electrical Wiring. Published at Friday, January 19th 2018, 17:49:47 PM. Connections should be secured against accidental loosening. Correctly tighten terminal screws and where a connecting plug is fitted, use the clamps or screws provided to secure it to its mating socket.

Measure your valve guides and compare them to your engine’s specifications to make sure they are centered and not overly worn. If they are worn, you can either replace them or use a special cutter pilot before continuing.
