Five new ‘advice’ checks concerning a.c. electrical systems have been introduced; 3.8.1 This check is a new ‘advice’ check concerning the type, location and condition of a.c. inlet connections (replacing deleted check 3.4.3). 3.8.2 This check is a new ‘advice’ check for the type of a.c. power source lead connections. 3.8.3 This check is a new ‘advice’ check of the condition of a.c. power source leads and connectors.


These three checks reduce the risks of people aboard the boat being electrocuted because of inlet connections, power source leads/connections of an inappropriate type, or in poor condition. 3.9.1 This check is a new ‘advice’ check addressing the fire/electrocution risk associated with using un-synchronised a.c. supplies simultaneously, and that male pins on shore-power inlet connections are not ‘live’ when an alternative power source is connected to the a.c. system. In addition to reducing the risks of electrocution, this measure will also reduce the risk of overheating and fire caused by using un-synchronised a.c. supplies simultaneously. 3.9.2 This check is a new ‘advice’ check introducing a check for the presence of a consumer unit on a.c. systems. The presumption is that that a consumer unit will include fuse and RCD protection. Unprotected a.c. circuits present a risk of fire and electrocution to persons on or around the boat.


Please note this further advice concerning examination preparation


which the BSS is emphasising. Boaters are asked to help themselves (and their examiner) stay safe by: q making available for examination the shore-power, battery charging or other power source leads for examination of type and condition; q providing information about the location of the a.c. consumer unit to the examiner in advance of the BSS examination; q where practicable and safe to do so, boat owners should disconnect shore-power, battery charging, and other power sources in readiness for the BSS examination.
