The MAX 10 was proposed as a stretched MAX 9 in mid-2016, enabling seating for 230 in a single class or 189 in two-class layout, compared to 193 in two-class seating for the A321neo. The modest 66 in (1.7 m) stretch of fuselage enables the MAX 10 to retain the existing wing and CFM Leap 1B engine from the MAX 9 with a trailing-link main landing gear as the only major change.

Reduction in maximum values of earth fault loop impedance in BS 7671. One of the changes being introduced by BS 7671:2008+A3:2015 (IET Wiring Regulations Seventeenth Edition), which was published in January and comes into effect on 1 July, is a reduction of maximum values of earth fault loop impedance (Zs) in Tables 41.2, 41.3, 41.4 and 41.6.

In other words, select the appropriate value from the tables in BS 7671 and multiply it with 0.8. This number should be higher than the highest measured Zs value for the given circuit.

Their physical size or rejection features prevent replacing a fuse with one from another fuse class.

However, in practice, ensuring the earth fault loop impedance (Zs) of the 110V RLV circuit is within the maximum permitted level usually represents the greatest challenge to installation designers. As stated above, BS7671:2008 Jul 18, 2019 · NAPIT’s Don Holmes provides us with more essential technical information. The maximum earth fault loop impedance values (Z s) in BS 7671 – or the equivalent tables in the IET On-Site-Guide (OSG) and IET Guidance Note 3 Inspection and Testing (GN 3) – are essential references when carrying out Z s tests.

Divide this value by the expected power factor of the 110V system and there's your earth fault loop impedance value.

Select from the list of protective devices (fuse's, MCB's, RCBO's) and device ratings to calculate the maximum permitted Zs value for your selected protective device.
