    Dear Sir,
    Your programs are useful unless we can fully understand the actual derivations i.e the formulae in the respective cells. However, most of your formulae in the respective cells are locked with password. Thus, rendered your program ineffective. This is the main reason
    for the many complaints from your readers.

    1. Could you let me know how do I unlock your passwords
    2. If there is any cost involved, please let me know:
    a) The process
    b) The cost
    c) What are my other benefits
    d) What are the eligible duration

    Looking forward to receive your quick response.

    Regards,
    (Mr. Gan Saik Ngai)

    1. You should not include FUR (Future) load when sizing Over Current Protection Device (OCPD) for a specific load. The size of the OCPD should Be to protect the current load, otherwise the OCPD is NOT protected.

    2. the NEC FLA of motor loads are HP driven and not KVA driven. Also the circuit trip amps can be up to 250% of the FLA. see NEC Table 430-250

    Hi Jignesh,
    I am working in a project where there are 12 nos. LV (415V) motors fed from MCC located about 1.1kM away from the motors. There are LCS located near the motors.understand from another project that in such long distance cases, when a stop signal is given from LCS, the contactor remains picked up due to the stored energy due to cable capacitance. Kindly advise some mitigation measures in this kind of situation to avoid mal-operation.
    Regards
    Debmalya

    Sir,

    The Selection of MCCB spreadsheet I can not select more than 120 sq mm cable size , so please update this sheet for other size of cable
