Either of these should work for your association table:

create table house_items (
    house_id integer not null,
    item_id  integer not null,
    foreign key (house_id) references houses(id),
    foreign key (item_id) references electrical_items(id),
    primary key (house_id, item_id)
)

create table house_items (
    house_id integer not null references houses(id),
    item_id  integer not null references electrical_items(id),
    primary key (house_id, item_id)
)

You'll probably want separate (single column) indexes on house_items.house_id and house_items.item_id as well.
