Three Phase Generator.

Zoomup

A local man is disconnecting from the grid due to rising costs. He has bought an AG-50 50kVA three phase diesel generator. The maker is Fuj[an Yihua Electrical Machinery Co. Ltd. The generator will be used for electric showers and a washing machine on a camping site. What advice can you provide for me so that all goes well with the installation. The certificate of conformity states 380 Volt, p.f. 0.8, 76 Amp. 50Hz.

Is foundation earthing a good idea whilst the concrete slab is being made?

Thanks,

Z.

    big fuel tank with isolator and drain arrangements, but the valves need to be lockable against theft.  Earth as TN-S and yes if there are steels in the foundation below damp course,  connect to them  but also decide where a rod could go if you need one .

    Make it very clear that a genset cannot take load step up of more than 30-50% of full load without stalling - quite what will depend on fly wheel mass, but even on a heavy model, no  sudden 20kVA loads please. Frequency and voltage regulation will be much worse than mains also PSC will not be very high Consider an earth fault relay or a 300mA  slow RCD at the origin.
