C1 - There is a danger present, risk of injury and immediate remedial action required; C2 - There is a potential danger present and urgent remedial work is required; C3 - Improvement is recommended; Issuing codes. It is not hard to find discussions between electricians on line who are reluctant to issue a C2 code. From Wikipedia, the free encyclopedia [1] : 620 Hydrocarbons are examples of group 14 hydrides. Hydrocarbons are generally colourless and ; their odor is usually faint, and may be similar to that of . They occur in a diverse range of molecular structures and phases: they can be ), low melting There are six levels of language proficiency (A1, A2, B1, B2, C1, C2) according to the CEFR scale. They are grouped into three broader levels: A1-A2 (Basic User), B1-B2 (Independent User), and C1-C2 (Proficient User). This basically states that, in general, sockets without RCD protection would be considered a C3 - Improvement Recommended. This is more serious and would be coded a C2 -Potentially Dangerous in instances where portable outdoor equipment could be used from that circuit. For example: If I have 3 capacitors connected in parallel, C1 = 470uF, C2 = 1000uF and C3 = 100uF. What is the capacitance of the equivalent capacitor? Using the formula: Ceq = C1 + C2 + C3. Ceq = 470uF + 1000uF + 100uF = 1570uF. A Code 1 (C1) observation means ' Danger present. Risk of injury. Immediate remedial action required.' A C1 represents an immediate threat to the safety of your employees, customers or guests and should be rectified or made safe as soon as possible. etjqC.
