Hello All
Electrical regulations vary between countries so there is not a global answer.
In the UK, all Public places that have live entertainment should have there electrical systems checked to comply with all regulations; and all the sockets should also be protected by an RCD. In addition to this all performers must have the equipment checked yearly (PAT Test) and be able to provide the required paperwork.
In Private clubs it is the responsibility of the owner to make sure everything is as it should be. (Heavy fines can be incurred if an accident occurs and health and safety measures have not been taken)
When purchasing a surge protector look for one that has a warrantee that covers the cost of replacement or repair of damaged equipment. (I know of one big manufacture that advertises this and has very good customer support, and the cover also includes a lightning strike on the electrical system)
Finally, if you have more then one piece of equipment do not be tempted to use an ordinary power strip connected into a single surge protection unit, as due to the way portable surge protectors work, full cover will not be provided. (There are plenty of surge protection power strips available)
Hope this helps
Bill
