Welcome to the website where you can pass online the CES CBT CD-8535 test on the subject «Cables, Cable Entry and IP-degree in Ex-area». Practice like this will help you as a marine specialist improve your knowledge with the help of online studying and appraisal practice. CES based on practical information and marine specialists experience.
CES tests developed for evaluating seaman basic knowledge by Seagull Company (rebranded as «OTG»), is an evaluating online-tool, used for revealing any professional preparation needed in specific fields of knowledge, defined by STCW.
CES tests have proven themselves as good tools for the selection and recruitment process, as well as advancing the level of knowledge of the current officers and crew. Ocean Technologies Group use various subjects for question creation, which includes:
Crowd and Crisis Management;
Integrated Navigation System (INS);
Ballast water management;
Handling and Stowage;
Vessel operation management and safety;
Marine engineering;
Maintenance and repair, etc.
Current test contains Seagull CES questions on the subject «Cables, Cable Entry and IP-degree in Ex-area». Those questions can be used for competence verification specialist capable of preventing accidental situations related with transporting safety, or also for self-examination.
«Cables, Cable Entry and IP-degree in Ex-area» subject includes theoretical and practical information about advanced training for work on any type of vessel. The test is designed to provide training for personnel working on ships of various types. The course offers the training that combines understanding and skills for working with electrical cables and equipment in hazardous areas on ships. This specialized test is designed to educate maritime personnel on the safe and effective handling of cables and cable entries in potentially explosive atmospheres on various types of vessels. Participants will gain in-depth knowledge of different cable types, their specifications and appropriate selection criteria for use in marine environments and hazardous areas. The course covers the critical aspects of cable entry methods, including the installation and maintenance of cable glands, seals and terminations to ensure the integrity of electrical systems. Trainees will learn about Ingress Protection (IP) ratings and their significance in determining the level of protection required for electrical equipment in different shipboard locations. Practical exercises focus on the proper installation and inspection of cables and cable entries, with an emphasis on preventing the ingress of water, dust and other contaminants. The curriculum also addresses the specific challenges and safety measures related to working with electrical equipment in explosive areas, adhering to international standards and regulations. Upon completion, sailors will be equipped with the advanced skills and knowledge necessary to ensure the safe and reliable installation and maintenance of cables and electrical equipment in hazardous areas on ships.
On this site Crew Evaluation System Test on the subject «Cables, Cable Entry and IP-degree in Ex-area» contains 17 questions you need to answer with no possibility to go back to previous question. Therefore, we recommend carefully reading each question and making decision with no hurry. In case you have some difficulty answering, you have also possibility to request a hint.

By the use of a blanking plug, where we seal of the existing hole and drill and tap a new one.
By the use of a reducer.
By the use of an adapter.
We are not allowed to modify certified equipment, we have to order a new one.
Ex certified cable gland has to be according to IEC 60079-0. With the regards to Ex d, which additional standard is applicable?
IEC 60079-1.

44.
45.
54.
56.
What is the minimum required IP rating for Ex certified cable glands?
IP 54.
IP 56.
IP 66.
IP 66/67.
What kind of gland shall we use when connecting an Ex i circuit in an Ex d[ic] IIB T6 Gb enclosure?
Ex di gland.
Ex d gland.
Ex e gland.
We don’t have to use a Ex certified gland since it’s a Ex i circuit.
What kind of threads is allowed to use in Zone 1 area?
BSP.
Metric.
NPT, but only for IIB and IIA gases.
All.
What type of gland has compression on the inner sheath of cable?
Compression gland.
Barrier gland.
MCT.
Thru gland.
When installing an Ex e motor located in Zone 1, the cable comes directly from the MCC (Motor Control Centre) and is not substantial compact and has hygroscopic fillers. Which of the following glands would you choose?
Ex e certified compression gland.
Ex e certified thru gland.
Multi certified (Ex d, Ex e, Ex nR) barrier gland.
Multi certified (Ex d, Ex e, Ex nR) thru gland.
When selecting a thru gland for a Ex e enclosure, which of the following do have to consider?
Thread size and the braids diameter.
Thread size and the outer diameter of the cable.
Thread size and the diameter of the inner bedding of the cable.
Thread size and the number of allowed cores through the gland.
Where would you find data regarding dimensions for cables?
Installation standard IEC 60079-14.
Since the IEC 60079-14 standard is additional to the low voltage installation standard these values would be given here.
